    I brought an A3 2010 2.0 sport back a week ago and was really happy with it until the DPF light came on yesterday. The car has done 41000 miles. I looked in the manual and did the 15 min at 2000 revs it advised and the light went off.


    I have been reading up on the problem since and feel a bit worried now that I'm going to be plagued by this problem.

    I was on a short trip yesterday but I had done a 100 run in it the day before so it seems strange it happened, although maybe at the garage I brought it from they had been taking it out for lots of short trips for test drives etc.

    My question is now I successfully regenerated it will that likely be the end of the problem or will it keep happening? To give you an idea of my driving i do a daily motorway journey of 12 miles x 2 to work with regular longer runs of 100 miles +.

    I phoned the dealer I brought it from and they were actually quite good and offered for me to bring it back for a look, however I recently sold my Porsche to change to this car because I was fed up of constant mechanical niggles and repairs and so I have bought the A3 with a view to hassle free driving!


    Its the first Audi I've owned, any help would be appreciated

    The answer to your question is Who Knows???? Its one of the problems that could come back or it might not. If it happens again in a shorter period of time it means the filter is beginning to block and the regen process is only partially rectifying the problem. I have just done 2 DPF deletes in the last week with the same fault but none of them could regenerate so out with the filter and ECU remapped to compensate for it. Both customers over-the-moon as no chance of DPF problems, failed regens or limp home ever again

    Get it looked at. The CR engines are much more reliable than the PD ones

    Doing what the manual prescribes IMO normally leads to more harm than good. You need to get temperature into the system. Generally the pre turbo temps need to be over 700 degrees to activate the regen (dependent upon conditions). There is hardly any chance of that happening when you are sat at 2000rpm and cruising.

    You ned to go up and down hills and leave it in 3rd gear up towards 3000rpm

    equally all over the above is useless if its a sensor which has failed because the car will neve know to activate a regen and therefore the owner ends up clogging it and killing the DPF!!

    If it was my car I would bite the bullet and get the DPF deleted so you have no more worries.

    Is the dpf covered by the warranty or is it wear or tear?

    It will be covered under warranty if filter blockage occurred as a result of a system fault.
