Hello everyone, I am new to this forum so hi to everybody. This is my first audi A4 which i have owned now for about 2 months, its a 2005 55 plate 2.0 tdi with 40,000 miles and i was very impressed so far until today. Driving home from work this evening up m1 and felt a sudden lack in power, thought it was just a bit of strong wind to start with at front of car so put foot to floor and absolutely no power there at all, being in outside lane aswell i got a bit concerned!,so managed to get of motorway at next junction. stop at lights, turned to green and put foot down,car accelerated to 2000 rpm and then nothing and it did this in every gear, so pulled over turned car off 4 a couple of minutes and tried it again, after that the car seems absolutely fine again! Has any one on here had a problem like this before? and does anyone know what the problem could be? Thanks in advance for any replies.
