Fixing this one (or one very similar) burned me bad (not literally) back in 2001. Most likely cause is a defective Motor Driven throttle Valve BMW S.I 12 07 99.

I am responding based upon your sympton description and not the generic P0340 (Camshaft Position Sensor Malfunction). I believe the P0340 is secondary to the MDK failure. Confirmation can be had by scanning with a BMW scanner and looking for specific BMW codes.

But by sympton and pratical experience I think its the MDK. The S.I. for BMW is pretty much BMW jibberish but it does list the replacement part number 13 54 1 433 414. warranty labor time was a little over a hour. They are not fun but not the worst to replace. affected a large group of cars.
