Hello all, I was wondering if you could give me a tip or two on my situation. I've got the late 2006 Sportback A3, 1.9 TDi (105BHP). I bought the car when it was 2 years old and immediately I noticed that when on idle, the engine seems to be slightly vibrating. The rpm needle does not show anything. About two months ago, I decided to have its ECU remapped to get some extra power and better fuel consumption rates. Within three days after the remap, the car vibrated and made a loud noise when accelerating from low rpms. I took it to the dealer for a test drive and they told me it needed a new flywheel & clutch. They gave me an appointment further down the line, as it is a 2-day job. In the meantime, I had the original ECU files replaced, as there were more things going wrong with the vehicle (loads of exhaust fumes, high fuel consumption, etc). Now that I took it to the dealer with the ECU in its original state, they told me that I just needed an ECU upgrade (which they performed, allegedly to fix a slight judder issue) and let me go. Because the extra power/strain is gone, the flywheel cannot replicate the problem when test-driving on a level. However, the vibration when the engine is on idle is still there, although it still is relatively imperceptible, unless you drive the car on a daily basis. I know for a fact that my flywheel is going, but it has not reached that point yet that under the engine's current power it will display any significant symptoms for the dealer to take me seriously and perform the repair. Any suggestions as to what I could do during a test-drive that would demonstrate the flywheel to be definitely on its way out? Thanks!
