I cant clear this fault code on a 320 cd sport 53 plate, bought the thing at auction and i think its on limp mode, managed to clear a EGR fault code and oine for 02 emissions, thought it might be cos the battery was flat and had to jump it, There was no oil in it when i checked before starting so i put some in, got it running but it wouldnt rev past 3grand. I have left it at the auction to go back through but would like to fix the problem it said it was a BMW specific code, is that why we couldnt clear it with our diagnostic???

Any help would be appreciated, i've got a lot of money now tied up in a car thats not running right!!!
