Vehicle owners told to stay on top of Servicing and Maintenance during lockdown.

More than half of drivers do not know when next service is due

Vehicle owners told to stay on top of maintenance during lockdown

Highways England and Aarons Autos are this week encouraging road users to carry out regular vehicle maintenance and checks during the current national lockdown after a new survey revealed that more than half (54 per cent) did not know when their next service is due.

Nearly a third (32 per cent) of road users admit they only carry out basic vehicle maintenance, such as checking their tyre pressure or oil levels, at best every few months or never.

This is in spite of advice to perform regular vehicle maintenance – even when a vehicle is not in regular use during lockdown – on top of the recommended annual service and mandatory MOT.

In response to the survey, Highways England and partners – breakdown provider, Green Flag, and Aarons Autos – are now highlighting the importance of basic maintenance and checks in helping road users to avoid breakdowns or endangering themselves and other drivers.

Without proper care and attention during lockdown, owners risk tyre problems, flat batteries, weather damage and issues due to fluid levels running low when they begin using their vehicle again.

Jeremy Phillips, head of road user safety, said: “While the country is in still in lockdown, we want to remind drivers to act now and carry out those important basic checks. 

“Doing regular maintenance, rather than waiting until the end of lockdown is in sight, will ensure their vehicles still work and preventable breakdowns are avoided when restrictions are lifted and the nation gets back on the road.”

Every year Highways England’s traffic officers deal with more than 85,000 breakdowns – 40 per cent caused by vehicles running out of fuel, poor tyre maintenance, power loss and engine trouble. 

Basic checks and maintenance can prevent many breakdowns, says Highways England.

Mark Newberry, commercial director at Green Flag, said: “Cars are designed to be driven regularly and the components rely on regular use to stay in tip-top condition. 

“A period of lockdown means many vehicles that may have been running every day could now be used less, which can lead to a number of complications.

“Car batteries are often the hardest hit. During the first lockdown, over 60 per cent of our callouts were for battery-related issues and the colder weather will also have an impact by reducing the battery’s ability to hold charge.

“Carry out a few basic checks to make sure your car is ready for when you need it. 

“Don’t leave it until your next MOT or service if you know or feel there is something wrong with your car.”

BMW 1 Series ABS Fault.

We are seeing lots of BMW 1 Series and 3 Series with ABS faults caused by the same fault.

The codes for this particular BMW were –

  • 5DC1 – Wheel Speed Sensor Rear Right Extrapolation
  • 5DC2 – Wheel Speed Sensor Exciter Ring Rear Right Periodic Fault

After seeing these codes on the Diagnostic Scanner we needed to take a look at the rear right Wheel Speed Sensor and Reluctor Ring to see if there were any obvious faults.

We could see the problem straight away, what seems to happen with the BMW drive shafts is that rust starts to build up underneath the reluctor ring pushing it away from the the shaft causing it to catch the ABS Wheel Speed Sensor.

Reluctor ring pushed out by rust.

To repair this fault you can either try to remove the rust from the drive shaft and replace the reluctor ring and wheel speed sensor (if required), we have seen problems with this repair as once the rust is removed from the drive shaft the outer diameter is smaller and the reluctor rings can come loose and cause more issues.

Damaged ABS Wheel Speed Sensor.

We replace the complete drive shaft to ensure this cannot happen, in this case we replaced the ABS speed sensor too as it had been damaged due to its contact with the reluctor ring.

New Driveshaft Fitted.

Once replaced we cleared all the fault codes from the BMW and carried out a road test whilst checking Live Data on our Scanner to make sure the speed sensor was reading correctly.

Hyundai I20 Timing Chain Noise.

A customer brought their Hyundai I20 into us to check for an engine noise which they were concerned about.

As soon as the car drove into the workshop we had a good idea what the problem was, it sounded like the timing chain was trying to escape from the engine!

https://youtu.be/MO0AlPe_pco

After having a good listen to the engine the next step was to strip off the timing chain cover to allow us to visually check the chain for condition.

With the timing chain cover removed we checked the timing chain, guides, gears and tensioner for wear, the chain tensioner was at full extension and the chain was still loose!

Whilst trying to turn the engine over manually to align the timing marks the chain actually started jumping teeth (it had only been the chain cover stopping this happening whilst driving).

Timing chain cover where the chain had been rubbing!

On inspection of the parts we could see everything was worn to excess and the customer had been very very lucky the chain didn’t slip whilst driving as that would have caused serious engine damage.

Once the timing chain kit had been replaced and the engine rebuilt the car purred as it should.

We later found out the Hyundai I20 had not been serviced for several years and thousands of miles leading to this problem.

Regular servicing using the correct lubricants will prevent premature wear on all engine parts especially chains, guides and gears.

EGR blocked on this Renault Traffic.

This Renault Traffic came into us with its EML (engine management light) on and had a lack of power.

The first job was to carry out a diagnostic code read which showed up several codes relating to EGR valve faults.

As it is quite a big job we needed to get authorisation from the customer to remove the front end off his van access the EGR valve.

Once we had removed the front end we could access the EGR valve and start to remove it, once removed we could see the problem.

Completely blocked EGR valve.

The EGR valve and pipes were completely full and blocked with carbon deposits which was stopping the valve from working properly.

Blocked EGR pipes.

We replaced the EGR valve and cleaned out all the pipes to and from the valve, this cleared the codes and allowed the vehicle to drive at full power.

New EGR fitted.

Unfortunately due to the amount of carbon build up in the pipes we determined that the rest of the intake system would have similar carbon deposits in them and may need cleaning in the future.

We advised the customer to take the van on several long journeys at an average RPM of 2500 this will allow the engine to carry out a regeneration of the DPF (diesel particulate filter) and help clean out carbon deposits from the intake system.

This will no doubt have to be carried out several times to get the engine into a good internal condition.

The biggest problem with modern diesels is that people drive them economically and on short journeys, this is what causes the carbon deposits to build up and cause issues, ideally they should be used for long journeys at least once a week to allow the engine to clean itself.

For more info on EGR or DPF faults don’t hesitate to contact us.

Golf / Jetta TDI with DPF and boost faults.

This Volkswagen Jetta came into us with its engine management light, DPF light and glow plug light illuminated. It had very little power and needed some attention.

Firstly we carried out a diagnostic code read to see what fault codes were causing the light to be on, several codes relating the Diesel Particulate Filter (DPF) being blocked or soot content to high and one relating to boost pressure lower than expected.

Next we tried to clear the codes and restart the car to find out which codes stayed live, in this case all the codes stayed.

We tried to carry out a Diesel Particulate Filter Regeneration which with this particular car has to be done whilst driving.

You have to drive the car in 4th or 5th gear at approximately 2000 rpm until the DPF light goes out, this can take up to 40 minutes depending on how blocked the DPF is.

The regeneration did not work, so back to the workshop for some more tests.

We tested the differential pressure before and after the DPF, this is done using a pressure gauge which is connected on to the pressure sensor pipes, if the pressure is to high the DPF wont allow you to carry out a regeneration and the DPF will need to be cleaned out using chemicals either on or off the car.

The DPF soot content on this Jetta was very high so we decided to remove the DPF and have it chemically cleaned.

DPF removed from car.

Whilst the DPF was off we decided to check in to why we were getting a code for low boost pressure, we checked the turbo actuator pipes for leaks which all seemed ok then we checked to see if the actuator was working using a vacuum tester, the actuator wouldn’t hold vacuum.

We removed the turbo actuator and tested it against a new one (see the video below)

Once the DPF had been cleaned out and we had replaced the faulty turbo actuator it was time to retest the the car.

We cleared the codes and took it for a road test, all the warning light extinguished and we had full power, brilliant.

After speaking to the customer we realised that the car had lost power several months ago and he didn’t have it looked at until now due to the fact of not just one warning light being on but three on the dash.

The car wouldn’t carry out a driven regeneration of the DPF (which they do regularly under normal circumstances) due to the faulty turbo actuator which then caused the DPF soot content to increase until it was full causing all the warning lights to come on.

The Moral of this story is ‘Warning lights are important‘ if you have a warning light come on on your car get it checked out before it causes any more damage.

Is your vehicle ready for your holiday?

There are a number of car checks you can perform both around the car and under the bonnet to help keep it in good running order and prevent a breakdown.

Getting your hands dirty under the bonnet might sound like something you should leave to the professionals, but there’s no reason why you can’t maintain some things yourself. 

Spending five minutes carrying out these simple checks every few weeks – and certainly before a long journey or an MOT – can save you a lot of time and money in the long run, not to mention help keep you safe on the roads.

To keep things simple, here are 12 simple car checks you can carry out today to keep your car safely on the road and on the right side of the law. We also have a quick video from RAC patrol Matt Woodbridge demonstrating four simple under-the-bonnet checks:

When it comes to preventing a breakdown, remember the acronym FORCES, which stands for Fuel, Oil, Rubber, Coolant, Electrics, Screen wash.

1. Fuel

car-maintenance-checks-fuel-aarons-autos
Use the correct fuel.

Check you have plenty of fuel in your tank for your journey. It may sound obvious but you’d be surprised just how many people run out of fuel, particularly in harsh winter weather.

2. Oil

car-maintenance-checks-oil-aarons-autos
Use the correct Oil.

Check your oil level is between the minimum and maximum mark on your car’s dipstick and top up if necessary.

If you don’t know which type of oil you need to use, refer to your owner’s handbook or speak to your local dealer.

3. Rubber

car-maintenance-checks-rubber-wipers-aarons-autos
Use good quality wiper blades.

When it comes to rubber, check both your tyres and wiper blades on a regular basis.

Check your tyres for general wear and tear, splits or bulges, and crucially tread depths (remember to check the inner tread too). Minimum tread level is 1.6mm, although in winter it’s advisable to have 3mm of tyre tread to help with traction and grip.

Also ensure you’ve got the correct pressure in your tyres, checking your owner’s handbook if you don’t know the correct inflation.

Examine your wiper blades and make sure they clear your screen effectively as these won’t last forever and need replacing from time to time due to splits and cracks.

In winter, you can prevent your wiper blades freezing to the windscreen by placing a thin sheet of plastic or cloth, between the wiper blades and the windscreen. Or you can try using de-icer or warm water to free them up before starting your engine.

4. Coolant

car-maintenance-checks-coolant-antifreeze-aarons-autos
Use the correct coolant.

Check your car’s coolant level. The last thing you need is a frozen engine or for your car to overheat.

Although it’s a sealed system and shouldn’t need to be topped up, you should always double check, especially before a long journey.

Check your coolant levels when the engine is cold and look in your handbook for the location of the filler cap and for the correct coolant and mix to use should you need to top it up.

5. Electrics

car-maintenance-checks-lights-aarons-autos
Make sure bulbs are fitted correctly.

There are plenty of electrics in your car – from headlights and fog lights to your battery – and they all need to be checked regularly to keep you safe.

Walk around the car and make sure your lights are all working, even the number plate lights, as you can be fined for having a registration that can’t be seen.

You should also check your battery, making sure the terminals are clean and tight (cleaning off any corrosion with hot water and applying petroleum jelly) and that the engine starts correctly.

If your engine struggles to start when you turn the key, get the battery checked out at a garage. If your battery is over four years old it may be getting to the end of its life and could let you down.

When you’re having your battery tested, ask them to check the starting & charging system and whether anything is draining your battery – this will give a better picture of your car’s overall electrical health.

If you are having your battery test ask them to check the charging system and the drain on your battery – this will give a better picture of your car’s overall electrical health.

6. Screen wash

car-maintenance-checks-screen-wash-aarons-autos
Use proper screen wash.

Check your screen wash level in the tank under the bonnet (check your manual for its location), topping up if necessary with a quality screen wash additive or pre-mix, which you can pick up in most petrol stations.

Screen wash is important all year round. In winter snow and grit cause dirty windscreens, while in summer bugs and pollen can easily smear your view – so never put off checking your levels

Make sure you’re prepared for a breakdown and are kept safe at the roadside.

Aside from the vital FORCES checks and if you feel confident enough it’s also worth carrying out a few additional car maintenance checks on other parts of your vehicle to extend its life and avoid a breakdown.

7. Engine air filter

car-maintenance-checks-air-filter-aarons-autos
Use good quality air filters.

A faulty or clogged-up air filter could reduce your fuel efficiency and lead to reduced engine power, which is why mechanics recommend getting it replaced every 12 months or 12,000 miles, whichever comes first.

If you think your filter needs checking or replacing, simply locate the filter (usually in a black box under the bonnet) and remove it, making note of how it fits before you insert the replacement and fasten the box back shut.

Check your vehicle handbook for instructions.

8. Spark plug (petrol engines only)

car-maintenance-checks-spark-plug-aarons-autos
Use good quality spark pugs

More of a replacement than a check, but spark plugs are integral to the running of your engine – one or more faulty plugs will cause an engine misfire so it’s worth knowing how to replace them.

Generally, spark plugs need replacing every 30,000 miles or so and you’ll need the right tools if you want to replace them yourself. Also check your handbook or consult a dealer to check that a DIY replacement is possible.

9. Brakes

car-maintenance-checks-brakes-aarons-autos
Don’t fit cheap brakes.

It’s hard to underestimate the importance of properly-functioning brakes, so keeping them maintained is essential.

Start off by checking the brake fluid level and if low, top it up – check your vehicle handbook for the correct fluid specification Be careful as brake fluid is corrosive, and if you feel unsure then get a professional to take a look at it.

Brake fluid should be changed at certain mileage intervals – again, check your handbook for service details.

10. Air conditioning

car-maintenance-checks-air-conditioning-aarons-autos

Whether it’s 35 degrees outside or barely breaking freezing, it’s essential your aircon unit is fully functioning. However, apart from visual checks of the pipework, there is not a lot for you to check yourself.

Air conditioning system servicing should be carried out by a competent person with the correct equipment. A typical complaint is when the air conditioning does not feel cool enough on hot summer days, this may indicate that the system requires re-gassing – specialist equipment is required and so should be entrusted to an authorised service centre.

11. Interiors

car-maintenance-checks-interior-aarons-autos

No-one wants their car to be known as a “skip-on-wheels”, so keep things clean with a regular interior clean, clearing out your footwells, wiping down your dashboard and keeping only the essentials in your boot.

It’s not just about being a neat freak, a clean interior also keeps you safe on the roads – you don’t want any discarded bottles dangerously rolling underneath your pedals.

12. Exteriors

car-maintenance-checks-exterior-aarons-autos

Keep the outside of your car clean with a regular wash. If you’re doing it by hand, focus on the headlights, brake lights and number plates as these help you see and be seen on the roads.

Keep all windows clean and clear at all times. As well as being unsafe, an unclean windscreen that limits your view of the road could see you fined for driving a car in a “dangerous condition.”

Should I take my car to a garage?

If you carry out these simple car checks, your car should stay on the road without seeing a mechanic for longer, but if a more serious problem arises you should always seek professional help.

Power Flex Suspension Bushes For This BMW Z4.

Suspension bushes on all cars go through tremendous stress on a daily basis, some manufactures have got the design right and the bushes can last the life of the car whilst other manufactures just didn’t quite get there!

One of the problems with BMW’s in general is the front suspension bushes. Most of the BMW range suffer with the front suspension arm bushes either failing or being so worn that it causes the car to wander on the road whilst driving and can feel unstable when braking.

Replacing the bushes with either after market bushes or genuine bushes does sort out the problem, but with the condition of the UK roads and the fact that most BMW’s come with low profile run flat tyres the new bushes can be worn out within a couple of years.

The solution on this BMW Z4 was to fit some Power Flex nylon bushes, these bushes are mainly used in Motorsport but can be fitted to road cars.

Watch this video to see just how much movement was in the old worn bushes compared to the new Power Flex nylon bushes.

On the Z4 replacing just the lower suspension arm rear bushes was enough to transform the steering from a loose discouraging feel to a nice tight direct feel that a sports car should have.

For more information on whether Power Flex bushes would suit your car or just for more information give us a call on 01332 205070

Citroen Berlingo with ABS Wiring Fault.

A 2014 Citroen Berlingo came in to us with an ABS fault to be looked at.

First thing to do was carry out a diagnostic code read to see why the ABS light was on, the particular code for this Citroen Berlingo van related to an open circuit on the rear left wheel speed sensor.

We checked the actual wheel speed sensor for a fault but it checked out ok, next job was to check the wiring from the sensor back to the ABS pump.

Most of the wiring for the rear ABS sensors is hard to access as it runs inside the van. once we had determined that there was in fact a break in the wiring from the left rear sensor and the ABS pump (by checking continuity of the wires) it was time to start stripping the interior and physically check the wiring for a break.

After removing the passenger seats and lifting the carpets to access the wiring we noticed part of the raised carpet flooring had been trapping the ABS wiring loom between a raiser and the body and over time had rubbed through the wiring and caused it to short out against the body.

ABS wiring trapped under the carpet.

We repaired the wiring and and rechecked for continuity through the loom which we now had. Time to clear the stored fault codes and check for a wheel speed signal using the live data on our diagnostic scanner, perfect, the signal was good and the same as the rear right wheel, time to rebuild and road test.

Land Rover Discovery 4 Front & Rear Wishbone Replacement.

The owner of this Land Rover Discovery 4 decided he wanted to replace all four of the lower suspension arms as they had excessive wear in most of the bushes (common problem).

After a bit of research he booked it in with us to carry out the work for him.

Anyone who has tackled this job before will know its not a five minute job, especially when the bolts seize inside the bushes!

First thing we always do on jobs like these is to wire brush all the bolts and spray them with freeing oil in the hope to make life easier for us.

This did work on 50% of the bolts but there were several that no matter what we tried they needed to be cut out.

After replacing all the arms it was time for a full geometry setup as the arms had adjustments for Camber, Castor and Toe.

I must admit once all the work had been carried out the Discovery 4 drove perfectly, there was no more wandering at speed the steering was precise and not loose, it felt like it should do.

We did advise the customer to bring the Discovery 4 back after a few hundred miles so we could re-check the geometry once all the suspension components had settled in.

Vauxhall Corsa D 1.2 (A12XER) Timing Chain Rattle.

We had this little Vauxhall Corsa 1.2 booked in with us for a ‘really bad engine noise’.

Once the car was in the workshop it became apparent very quickly what the noise was, the Timing Chain was rattling so bad we were surprised it hadn’t jumped a tooth and caused engine damage!

When we were stripping the engine down to put the Timing Tools in place we could see just how badly stretched the chain had become, the crank locking pin went straight in but both cam shafts were out by quite a lot.

There are several variants of the Vauxhall timing chain engines most of which requiring different timing tools which we have, 1.0 – A10XEP, 1.0 – A10XER, 1.2 – A12XER, 1.2 – A12XEL, 1.4 – A14XEL, 1.4 – A14XER, 1.4 – A14NET to name just a few.

Timing Tool A is for the Camshaft Position Rings, Tool F is for the Camshafts.

After removing the timing chain cover we could start to see what had caused the problem, the oil was very black and there was a lot of burnt carbon oil inside all the covers.

All engines require regular servicing to keep them in tip top condition but especially modern engines that run a timing chains rather than a timing belt, we are seeing more and more engines requiring timing chain kits prematurely due to a lack of servicing, poor quality oil or the wrong spec oil.

Once we had replaced the timing chain kit and re-aligned all timing marks it was time to clean all off the engine casings and refit, replace the oil and filter and refill the coolant.

When we removed the oil filter this gave us another indication of what had caused the problem, the middle of the oil filter had been sucked in, caused by the paper element of the filter being completely full of oil carbon and struggling to allow fresh oil through it, which in turn starves crucial parts of the engine of oil (timing chain) allowing them to wear, over heat and stretch.

On this particular car we advised the customer that over the next 20,000 miles they should have several oil and filter changes to help remove carbon deposits that we couldn’t see or get to whilst doing the job and this will help increase the life of their engine.
