Hi all really p****d off ive just fitted a td05 and z4 ecu to my wagon and when i started it up it sounded a bit lumpy and seemed to misfire and smoke white smoke something stupid. Anywats tried to drive it and it just had no power what so ever got to about 10mph. Switched off for about 10 mins and tried again at first it seemed better for about 30 seconds then just wouldnt rev again all the time pumping out loads of smoke and misfiring. Any ideas on this is it a dodgy turbo, have i got some pipes plumbed in wrong or something else?
Thanks.

 

Firstly, don't drive your car again till you get the problem sorted, you'll destroy the engine. I strongly advice you to get a scooby specialist to look at it.

Problem could be anything:-

Turbo coolant leak.
Knackered turbo.
Defective ecu.
T piece hoses the wrong way around would give you no boost at all!

There are alot of possibilities.
