I feel and hear a wobbling sound when I let off the gas pedal below 1500rpm. It feels as if its running out of breath. I don't hear it after the turbo kicks in. Is it normal anyone else the same issue?

Not sure what a wobbling sound is but my guess is it could be the waste gate closing? Any mods? How many miles? Same when its cold and hot?

No mods and it has 13k miles and in operating temperature. I hear it when at low speeds or my foot off the gas and decelerating. It might be the grinding or a alignment but it went through its 12k service few weeks back with no comments from the rep.

how about checking the wheel bearings? seems common with BMWs starting with E90s.

I have heard this... wobble is a good description! Only in first and only when off the gas like you said... woo woo woo woo. My 135i did it too. It is the turbo. Nothing wrong.

I will pay attention to mine and see if I have the same noise/sensation.

I went to dealer to get it checked and the after a short test ride the tech came to a conclusion its due to the uneven tire wear on the outside. The car has nearly 15k miles. I decided to wait until next service to get them changed. It came with continentals and I will probably go with Michelins.
