Help

In the past 24hrs my car has suddenly decided to drop into limp mode. Car is a 2l tdi 140bhp version with 56k on the clock. The DPF light came on on Saturday but it cleared on Monday during a long motorway run. The car wasn't driven on Sunday.

I brought it to a local garage and after checking the engine diagnostics they performed a "re-gen" on the DPF and reset the faults. However when I picked it up again this evening after a few mins of driving it dropped back into limp mode.

The faults now point to a faulty sensor according to the diagnostics.

Is there anything that I can do/suggest tomorrow when I get it back to him?

DPF pressure sensor, very common fault. Easy to replace if you have access to VCDS, if you don't then its a dealer job. The replacement sensor requires adaption to learn how full the DPF is from scratch, hence the need for VCDS.

 

I replaced the sensor on my old PD140 MK2, there is a thread I started with the required VCDS coding to start the adaption.

Thanks Mannyo

Will let the garage know and report back on the repair.

Update

New pressure sensor fitted and coded with vcds. All looks to be nominal so fingers crossed all ok in future.

Old one was Made in USA - new one is Made in Malaysia.

£100 plus the part which I picked up from skoda in cardiff
