throttle body made of alu and throttle flap made of steel. We tried frosting throttle body to -40 and it looks like in this condition it is possible, that aluminium body became a little tight for steel flap, so it can't move until warming up to -25..-20.
- new thottle body doesn't fix problem. (Old throttle body was almost clean, and no changes after cleaning, so we tried new throttle body).
- we both have 325i 05 model year with n52b25 engine (with 2 DISA intake manifold). In 2006 BMW changed intake manifold to new revision with another crankcase separator. So we suggest this is tha main reason of our problem.
Purettava tarkistettva mitä on syönny, kun muutakaan ei keksi......!
Mikä oli tuo parannus??
