Loose turbo actuator rod on the N47T and N57T: lack of boost

Engine / equipment

N47T 2.0 and N57T 3.0 diesel with a variable-geometry turbo

Period mentioned

BMW bulletin of June 2018

Symptoms

Lack of power because the turbo is not building boost, with the engine warning light on.

Possible cause described

The clips holding the rod of the variable-geometry turbo actuator come loose, so the actuator no longer moves the turbo properly. BMW brought out a repair kit with improved clips and a new rod.

Check for the garage

At the garage: read the engine fault memory; BMW’s code is 244C00 (boost pressure too low). Check the actuator rod and clips; according to BMW the turbo does not need to come off to replace them.
