Hi there im new to the forum, Anyone had this problem.
I have just bought a BMW E46 320d 150bhp 2003 only done 80k, problem is no Boost.
Turbo looks new and has no play at all on the shaft and turns very freely.
Starts first time no strange noises but will only rev to 4000rpm.
You would think it was a 306D you were driving not a 320D.
No lights on the dash.
Might be vacuum hoses im thinking.
