Wondering if you can possible help. I notice that my car has a vibration right around 2000 rpm. If I'm sitting still and rev the engine, the revs will be smooth until it reaches 2000 rpm and then there is a
noticable vibration until around 2200 rpm and then smooth again. I've recently had a carbon clean done, new injectors and plugs. It almost feels as there is a miss at that rpm (no CEL).

Sorry for the weak explanation but I thought someone might have some insight!

If you have an S4 it may be better to post in that section since it's a difference motor from the RS4. But if u have a lw flywheel I'm not sure that noticing some vibration would be considered as odd.

Sorry, signature changed. I used to own the avant but now own an RS4.

I think the flaps open in the manifold at around that rpm. Could be getting stuck or a vacuum leak.
