⚠️ DPF lights on and won’t go off? Get it diagnosed asap as the majority of the time there will be a failed supporting component required for regeneration.
🚗 Here we have a Vauxhall Insignia 2.0 CDTI (2010 – 145,219 miles) booked in for diagnostics consultation and Engine Carbon Clean.
The owner had called us up with DPF issues and managed to get a diagnostic code read performed which indicated an issue with the ‘DPF differential pressure sensor – implausible signal’.
We advised over the phone to get a new one fitted asap.
Once fitted the lights stayed on as with these sensors they often need to be recalibrated on the diagnostics (make and model dependent).
We arranged to come and perform the pressure sensor relearn and also an Engine Carbon Clean at the same time.
🔎📊 Initial diagnostics on arrival confirmed the pressure sensor codes were still present and active.
👨🔧 We then performed the pressure sensor relearn procedure and the codes switched to historic at this point.
📊 The codes then duly cleared and with all the other live data looking fine and DPF soot content not too high the vehicle would regenerate naturally when next required.
👨🔧 Now on with the clean and the engine note soon smoothed out and quietened down and by the end was quiet, smooth and responsive again.
