2000 SS A4

1. Vibration in Park and Neutral @ 1,450 RPM

2. Vibration when taking off slowly, at the top of 1st, 2nd, D and OD (Every time the car hits 1,450 RPM)

3. Vibration on deceleration around 45-50 mph (1,450 RPM)

4. It runs pretty smooth otherwise, the vibration will go away depending on speed / RPM.


- Engine doesn't flop around when brake torquing a little in Drive or Reverse.
- Trans mount seems fine, Trans not hitting tunnel when shifting in/out of gear
- Bangs thru all the gears fine, runs out good, no codes for misfire.
- Stock engine mounts, Stock Trans mount


Mechanic is trying to tell me I should try injectors and plugs
I'm thinking not because it vibrates on deceleration with foot off of gas pedal
Maybe the flywheel or converter?


I'm searching around but any help would be much appreciated

Would a bad harmonic balancer cause these types of vibrations?
Or would the stock engine mounts soak up the vibration and make it un-noticeable?

Anyone hear of the Flex plate or Torque Converter causing vibrations in A4 cars?
Is it a common problem?
