Good evening and hello to all.
I'm new to this forum, having been recommended this forum by a friend I'd like to run something by you lot in the hope someone can help. The turbo on my woman's 2006 E90 320d went a couple of weeks ago. She had the whining noise and tons of white smoke also the engine run on after the key was removed for around 40 seconds. I took it off and it was quite obvious that it had gone. I ordered a reconditioned one and put it on today. I cranked it over with the pump relay removed for a long time until I had oil pressure. Then started the engine, it runs ok but when I give it some throttle it's as though it has a very small effect on engine speed, it doesn't really rev at all,it also make a slight noise like a dump valve when the engine is turned off, it'd be appreciated if someone could shed some light on this it'd be appreciated.
