Hello friends,
I have recently purchased Audi A6 Avant 2.0 TDI Limited Edition 2008
the car is very nice and drives very nice until 3 weeks ago, when it started shacking and little bit knocking sound when start the car! it does it only when the car is warm. The first start in the morning when it's still cold it smooth and nice, but the second start after the car is warm it shakes and knock... I went to Audi they said is the Flywheel, but for some reason it doesn't sounds like being that. - ANY IDEA'S
Also just today in the morning when I went out, after I started the car and start driving in about 20 meters distance the spark light came ON, and the car lost power, it was raising the RPM up to maybe 3500 but didn't speed up... I believe it entered in some emergency mode. After I have turned off and start the car again it was back to normal, no lights on! in about an hour later, I was going back home, the same thing happened but this time the engine light came on.... after I turned off the car and started again, the spark light was off but the engine lamp is still on and the car is working normal. Any suggestions? I do have an appointment for a diagnosis with Halford's on Thursday because of my guarantee works with them, so I need to take it there...
Any idea or suggestions are welcome...
