Hi I have a question for anyone who might know,
I'm running a 2000 S4, 140,000 KM.
My issue is sometimes when I accelerate I get a vibration or a shaking feeling, like the acceleration isn't smooth. I have replaced my tranny mounts which were somewhat shot, my motor mounts are still very strong and I have done all the usual maintenance for my cars mileage etc.. Does anyone have any ideas, I was thinking its possible it could be my flywheel?

Thanks in advance.

 

It's really hard to say, maybe a snub mount, suspension arms, or a the diff mount.

 

I did my snub mount,
I know my front right strut is leaking and i ordered coilovers to replace all my suspension, but i don't think its suspension related because it is only when i accelerate. Is the diff mount a typical suspect on that as well?

 

Could it be a boost leak? When you have one you can get jerkiness upon acceleration. I'm not sure if that's the type of shake you're talking about though.

 

A boost leak sounds like it could be possible, what is the best way to test it and see where the leak is coming from?

 

look on AWE site, they sell or provide instructions on how to make and test for leaks.
