M52TUB25 Engine...
Ok, every now and again when i started the car, the tickover would fluctuate between 0 and 3500 rpm, then when you eventually got it to tickover, there would be no bottom end torque. You had to rev it a fair bit to get it off the mark.
Then, it would be fine for a few days.
Thing is, its now doing it all the time.
I've changed the fuel filter, as i thought it might be full o crap, and in fairness, it was, but its still doing it.
I've done some reading and the vanos seals seem to be a recurring theme.
Or the idle speed controller....
The idle speed controller wouldnt make it drive "flat", though would it?
(when i mean flat, its like you have to rev it to 3500 to make it move, then you have to feather the throttle to keep it moving...)
Now the vanos thing doesnt look terribly hard to do, i just dont fancy spending a day in the garage only to find it was the idle speed controller!!
I havent had the codes read, BUT....does the engine light have to come on to lodge a fault in the ecu? cos its not coming on...
Any ideas, o fountain of broken bmw knowledge...?
