BMW N47 2.0L Turbo Diesel engine rebuild from our workshop.
It's well known that some BMW engines have problems with inlet manifold swirl flaps or their moteur. In this caseone of the flaps fail to oppen and stayed stuck due to high carbon and tar accumulation in inlet manifold. High intake pressure caused it to snap and it went directly to combustion chamber causing further damage to piston and valves.
Once again our mechanics were able to diagnose it - strip and fully rebuild the engine.
Now happy owner have his car back on the road!!!
