I was not aware they had a tune for the e70 diesel, but now that I think of it there may be a few posts on EU cars. Go to the 'diesel' subforum for more info.

I am not concerned about the motor, so much as all the other items that will cost you...

In terms of 'verifying', I think you need to hook it up to an autologic and read the DDE module.

Finally, the 2009 has the CCC based idrive. You CAN upgrade to the newer CIC based system. A few folks have done this, apw607 (I am just guessing at his name, something like that) had done it as i recall. About $3kUSD plus labor. Not that hard.
