Default Flutuating Turbo on my wifes BMW 320D.?????

We've had the car for several years and around several thousand miles under full accelleration the turbo fluctuates on and of.

1.Anybody know why on the off chance

2. I have located a Turbo off a 2004 320D, however, i',m not sure if it will fit as mine is the 136BHP model and the one i intend to get is the 150 BHP mode.
Will it fit ok????????

Check all the breather pipes, it's possible they're full of crap.

If the turbo works now and again its unlikely to be the turbo itself. Its the plumbing/wastegate/sensors or electrics. D

My Fiat coupe did this, it was the boost regulator, cleaned it out with WD40 and then it was ok, just make sure you get the tubes back on correctly, I didnt and boost went up to 1.7 bar !

No offence here mate, but you may be better off taking it to a BMW ind for a diagnosis - could be cheaper for you in the long run. Try bmwland forum for pointers.D

Good point, hopefully they can pick the problem up on the diagnostic test.

Have you cleaned the EGR valve yet ?

Did mine the other day (150bhp) and cleaned out quite a few mills of crud, make a dif to the performance, also been told its worth doing the turbo air filter (different to the normal air filter).

Check BMWLand bbs for more info and step by step guides.

very helpful people in here:

www.BMWLand.co.uk - Where Power Meets Control - UK BMW Car chat site Forum :: View Forum - 3 Series

pre-facelift 320's are prone to turbo failure, although yours doesn't sound like it, prob worth getting it checked out properly.
