anoying vibration

[jody]

I have an s1 which has this vibration when you come off the throttle!. When stood still if you bang the passenger seat you can also hear what i think is the vibration but where the hell is it!!!!!!.
Does any one have a simular prob or any ideas?

Could be the rear undertray rattling -- that is commonly heard when the throttle is lifted. A loud buzzing booming noise.

But seeing as you also hear it when you bang the passenger seat I would start by looking under the seat for loose rubbish, and check that the seat is securely bolted to the chassis floor.

Yep check the seat first and every few months remove them to clear out all the rubbish that gets in there. You will be amazed what gets down there.

Last time I took my passenger seat out I found 2 asylum seekers
