mach schnell, the TSB# is ENU1726 for the following engines:

The TSB says the new control spring is "as of":
Engines manufactured since December 5, 2005 as of engine numbers:
M96.25 61 6 04763
M96.26 62 6 03668

The date is not that important (except that if your car was built before that date it couldn't have the new control spring). If your engine number is below the engine numbers above (depending on model) -- then you need the new control spring.

You can find your engine number in either your warrenty book or owners manual. I don't remember which. It is in the first few pages.

I hope this is helpful, but your vibration sounds like it is much worse than the issue covered by this TSB.

Good luck and let us know how it works out with the dealer.
