Hi All. I'm new here, so if anybody can assist, that would be great.
have an M47 engine in a BMW 120d. It has the EGR, Swirl flaps, and 02 sensor engine management lights on.
The solinode that controls the hoover egr was not holding hoover, so it was changed. The hoover egr has been cleaned out. No better still.
Swirl flaps on the removed intake manifold were checked, and they all moved without any issues. It has through a solenoid test, holds hoover and functions as it should. Also passing inspection was the flap actuator.
cleaned map and Maf sensors. There were no boost leaks found despite a search.
The car handles OK, but the turbo seems lifeless and has no genuine power.
Please assist.
