X5 M Engine Fault Reduced Power Warning

[paqs]

Hi Folks,

At the weekend my X5 M with 700 miles on it reported an engine fault reduced power warning and went into limp home mode, the message cleared on the next restart.

Went to the dealer today and they said the car had stored a load of errors related to the left bank vanos indicating cam timing errors, he said these can't have been *reel* errors as the engine would have shut down completely.

They reset the codes and ran some diagnostic sequence on the engine which reported all was ok, no faults found and sent me on my way.

Within 2 hours I had the warning back and was back in reduced power mode until I restarted the engine again. The dealer thinks the car is suffering from software issues and is going to talk to Germany tomorrow.

Anyone come across anything similar, not impressed, 2 week old car with 700 miles on it!
