2016 Ford Transit DPF soot content to high.

This Ford Transit came into us with its Engine Management Light (EML) on and running in Limp Mode, after a quick diagnostic plug in we could see that the DPF soot content was well over 100% and it was unable to carry out a dynamic regeneration.

Vehicles with DPF’s require a long run at least once a fortnight to allow for a Dynamic Regeneration of the DPF.

We cleared the codes and attempted to carry out a static regeneration of the DPF which again was unsuccessful.

By monitoring the voltage of the exhaust temperature sensors we could see there was no change during the whole procedure and the exhaust temperature didn’t go above 170 degrees.

The first thing to check at this point is the Diesel Vaporizer which is located in the exhaust front pipe (normally seized).

Once we had removed the Vaporizer it was obviously blocked (see video).

We cleaned the Vaporizer and made sure the feed pipe wasn’t blocked and also checked the heater element was working by spraying WD40 into the Vaporizer and powering up the heater element with a 12v power probe, the WD40 should start to mist out of the little hole.

Next we refitted the Vaporizer and attempted the static regeneration again.

Success, the voltage of the temperature sensors dropped and the DPF temperature went up to over 600 degrees and you could smell the soot and carbon being burnt out of the DPF.

Lastly was a long road test to make sure it didn’t go back into Limp Mode and no codes returned.

Fiesta EcoBoost oil warning light on?

This Ford Fiesta 1.0 EcoBoost was brought into us with its oil pressure warning light on and its engine sounding a bit noisier than it should.

After stripping the engine our previous guesses turned out to be correct, the wetbelt had been degrading (as they do over time) leaving deposits of rubber in the oil which were being sucked into the oil pump pick up and causing it to block subsequently causing low oil pressure.

OIL PICK UP FULL OF RUBBER

If this problem is left to long it can cause serious engine damage as it is starving the engine of its lubrication.

On this EcoBoost engine we replaced its wetbelt kit and oil pump belt and also decided it would be a good idea to replace the oil pump itself rather than clean out the pick up (as it was so bad).

Once the job was completed it was time to see if the repair had worked and turn the engine over on the key!!

Success, the engine started, oil warning light went out and it purred like a kitten.

WETBELT DEGRADED AND SPLITTING

We think the biggest issue with this particular engine was caused by a lack of servicing, we know the wetbelts degrade over time leaving rubber deposits in the oil but with regular oil changes most of those deposits would be removed from the engine and not be allowed to block the oil pick up.
