DME issue

julian7437 · 11-09-2023, 01:01 PM

Long story short... been having wastegate/wastegate actutator issues with my 2020 X4MC pre 6/2020 build. Replaced 3 actuators out of pocket because of being tuned. In the course of all this, apparently the lines that connected the wastegate actuator to the DME got chewed up or corroded or whatever and it caused the actual portion of the DME to short out... leading to a permanent drivetrain malfunction leaving the car in limp mode. After multiple voltage tests to that portion of the DME, its pointed that I need a new one. Question is, are these DMEs repairable?

I wonder if this is a common issue because I as well had to replace wastegate actuator out of pocket but I’m not tuned
