Dpf cleaning - Mansfield and Ashfield

20/07/2024

Intriguing dpf fault on this Mercedes E class.

The car was initially presented for a dpf assessment due to a warning message on the dash.

Unusually, other than the fact that the dpf was actually blocked, we couldn’t find any other faults.

We ask our dpf customers to fill in a questionnaire about their cars history and their driving habits , as part of our assessment. This revealed that the problems started after the car had received an “adblue solution” at another garage.

The cars software had been badly altered to remove an adblue fault, but had triggered issues with the dpf system.

Using our tuning tools, and with the help of Avon Tuning, we were able to reset the software back to original, and repair the faults.

The car was then returned to the customer for a few weeks, but returned today for a free follow up assessment to check no further issues are pending.

Another win for Yardleys, The DPF Doctor, and Avon Tuning.

We had this Nissan Juke in with a reported DPF fault.

The initial code read showed a fault with the dpf pressure sensor, however our in depth assessment showed that the sensor was working correctly, and the dpf was actually clear and didn’t need cleaning.

We fixed the underlying fault, then carried out an extended road-test to prove that there were no more issues with the vehicle.

Didn’t require a sensor, didn’t require a clean.

A very tidy Vauxhall Vivaro in for dpf assessment today.

When the customer answered our pre-assessment questions, we were almost sure this wasn’t going to be a dpf issue.

Carrying out our assessment confirmed our suspicions.

The key part of our job is not just reading the fault codes, but measuring and interpreting actual real life data.

Can you spot what the problem is just looking at the before and after boost pressure graphs?

This vehicle had been “diagnosed” at two other garages before coming to us.

There is a reason we insist on carrying out our own vehicle assessment, it’s much more than just plugging in a code reader.

Fixing the cause not the symptoms.

Another blocked dpf job completed.

• No clean needed.
• No forced regeneration.
• No fuel additive used.
• No illegal dpf removal.
• No unnecessary parts.

Volkswagen Caddy in for assessment due to dpf, engine management, and glow plug lights on.

The only fault code present was for regeneration duration.

During our initial assessment and roadtest we found a cooling system fault that was actually the cause of the dpf issues.

Fault fixed, and an extended roadtest, the dpf carried out its own regeneration, no clean necessary.
