When excelerating first seems ok then in the rest of the gears when you get to just over 2000rpm the turbo kicks in then almost as soon as you get a burst of power it sort of disapears and continues to excelerate slowly.

First port of call would be to have the diagnostic codes read at a good BMW specialist or main dealer, have you had any fault lights up on the dash?

Also is it a 136bhp M47 engine or 150bhp M47N engine?


Also congratulations on posting the 1000th thread in this section, you win a cookie :rofl

Not sure of the exact setup you have. But may be worth checking/testing;

- control boost valve
- recirculating diaphram
- general splits and wear on pressure hoses for the turbo
