Cuprabob Posted September 27, 2013 Report Share Posted September 27, 2013 (edited) It's either a faulty pressure sensor on the DPF or tje DPF is clogged. Have you tried to force a regen by driving at a constant speed for about 20mins with the revs around 2,800rpm? If that doesn't work you need to take it to a garage for them to do a forced regen or see if the pressure sensor on the DPF is faulty. I've heard of a few pressure sensors failing on newer VAG diesels. Edited September 27, 2013 by Cuprabob Link to comment Share on other sites More sharing options...

Any idea how much for a garage to sort if its the pressure sensors? I was thinking of getting a new car anyway this may just speed things up.

Cuprabob Posted September 27, 2013 Report Share Posted September 27, 2013 (edited) Sorry, I don't know the cost as all the ones I've heard about.were.done under.warranty. At that mileage it probably is the sensor unless you do a lot of short journeys or town driving to clog up the DPF.

At that mileage it probably is the sensor unless you do a lot of short journeys or town driving to clog up the DPF. I do about 19 miles to work a day so kinda middle of the road type journeys. The car is just out of warranty so maybe worth seeing if they will do it as a good will gesture. Link to comment Share on other sites More sharing options...
Cuprabob Posted September 27, 2013 Report Share Posted September 27, 2013 (edited) Certainly worth a try as it's a common fault, if it turns out to be that. Just had a quick search and you would be looking at around £50 for the sensor and probably 1hr labour to diagnose and replace, so looking at £150 to fix Edited September 27, 2013 by Cuprabob Link to comment Share on other sites More sharing options...

Will give them a phone and see what they come up with. Link to comment Share on other sites More sharing options...

kennymc Posted September 30, 2013 Author Report Share Posted September 30, 2013 I have called the stealers today to ask for a rough guesstimate on cost going by the fault codes. Waiting on them getting back to me. Link to comment Share on other sites More sharing options...
kennymc Posted October 1, 2013 Author Report Share Posted October 1, 2013 Well stealers never got back with info so spoke to an independent (A 4 audi) in glasgow. The guy said almost certainly the DPF differential pressure sensor. He said about £140 for the part and the regen to clear the DPF. Stealer wants nearer £200.

Cuprabob Posted October 1, 2013 Report Share Posted October 1, 2013 That's not too bad then. Although I've not used them personally, I've heard good things about VWAudi repair centre in Duntocher and Bothwell. A 4 Audi also have a great reputation.
