Hi! I just bought an vw Polo 1.6 tdi 2010 mod. I have been driving it for couple of weeks and i started to av problems
When starting the car, it goes normal. But after just starting to drive, the idle starts to "hunt". It goes from 1000rpm to 1200rpm and back to 1000rpm. If I stopped the car and turned it off and starts it again, then it goes normal until I start driving.
Then sudden the DPF warning light turned on. So i went for a drive about 1 hour with 3000rpm. Nothing happend.
And today the car went in to limp mode. The fault code was "P2458". The codes just says that the DPF couldnt regenerat it self.
The last owner says that the DPF was replaced and the EGR valve was also changed about one year ago.
Do you have some idea of what this could be?
With best regards
1.6 Polo DPF fault

Re: 1.6 Polo DPF fault
Do a DPF delete on the ecu and take out the DPF in the exhaust pipe. You will have no problem after that again.
