    Hello All, so earlier this week my car threw the engine management light which did not go out. Car drove fine and has good MPG at around 780 miles to a tank of diesel. Way better than the last A6 I had with the older engine. I read the code and reset with VCDS and this morning the engine managment light came on again. I have not had the car long but from a private seller so no comeback . Car has been driven 3000 miles since purchase so perhaps I am unlucky.

    Any way VCDS log is below:

    I would fit and calibrate a new genuine pressure sensor and then carry out a forced regeneration.

    Cheers Crasher

    Would you happen to know the part number. I suspect it’s a Bosch sensor so can I purchase one from GSF if the manufacture part number is the same?

    Thanks

    No, a genuine sensor from TPS or Audi, from painful experience I will use nothing else. It is VIN specific.

    Hi Crasher, quick question. Is that both pressure sensors?
