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!

That's unfortunate. Have you been properly breaking the car in? Or have you been driving it hard from the get-go..... Honestly lol

It's not your fault. i did pretty much the same thing..
for the fail safe mode problem, they updated my software to their latest spec, they also hooked it up to germany and had techs there take a look at it, what they did i couldnt tell you. about 160 miles after it was updated it failed, just doing a highway run. then after the techs "fixed it " it failed, 2 more times all around and under 200 miles. on the 5th fail i was having a talk with bmw about replacing the car, while i waited to hear from them it failed again (that was nail in the coffin) they had no idea what was wrong, they still do not know. :dunno:

i can try to find out, but i wasnt told anything to specific, just how far it avg' between it failing. one time i took off at light next to a vette and it failed, 2 others were just driving on the highway and the others were getting off an exit and picking up a lot of speed;)

all were in M mode sport if i recall correctly, the speeds varied greatly along with the rate of acceleration...

ill see what i can find out for you, i should be picking my car up (again) very soon... (i am still using it till' the new one arrives)

good luck with your car i really hope its not heading down the path mine did :dunno:
