Slight Vibration around 2250 RPM - what could it be?

I've had a weird vibration when the car is around 2250 RPM especially in 3rd or 4th gear, but it also does it in 2nd and 5th. Most prevalent when accelarting softly on my morning commute. It goes away after 2500 RPM. It's something new, never done it before. I feel it mostly on the steering wheel since that is my main connection to the car, but it's not exclusively on the steering wheel. Feels like I'm running over very little rumble strips on the road.

My first thought was motor mounts, but I really have no idea. Have any of you been through this?

I had the clutch and flywheel replaced 2000 miles ago.

I had a similar problem, and it turned out that the heat shield was rubbing against the exhaust.

Maybe one or more tire need to be rebalanced? Have you hit any potholes recently maybe your rim was bent VERY slightly.

The search of that perfect E39 M5 has ended...

No, I doubt it. I'm a tire pressure fanatic. I have a big, vertical Ingersol Rand compressor at home and I always have them perfectly inflated and inspect them for the smallest of nicks. Plus, I'm the only one that drives the car and haven't hit anything lately. Plus it's always at the same RPM, not the same speed, which tells me it's an engine or drivetrain issue.

I had this exact same problem about 1.5 years ago with a Audi A8L. Drove me crazy. Turned out to be a bent exhaust heat shield. Can you pin point the area roughly that its coming from?

Got ya, only reason I brought it up is that I have a very similar issue but only on the same speed, not rpm and I cannot visually tell my rim was bent until I went in for a balance and the tech there told me. Sorry couldn't be more helpful!

Dropped the car off at the dealer on Saturday. I went the extra step of writing the speed in each gear where it vibrates. Hopefully it eliminates the SA calling to tell me the couldn't duplicate the problem. Will post results of the issue.

Arrrgh! Got a call from the dealer. They cannot duplicate the problem. I'm going over there to take a spin with the tech and personally show him the problem. This sucks.

I'll ask them to lift the car and check the heat shields. I wasn't going to tell them to try that (let 'em figure it out on their own), but at this point I just want the car fixed. Updates coming later today.
