GL350 BlueTEC Diesel Engine Light On: P2002, P2454, P244A, P203D - What Does It Mean?

Model: GL350 Bluetec Fault Code: P2002 Posted: 2020-08-19 14:46

My 2010 GL350 BlueTEC diesel engine light is on, and I'm getting diagnostic codes P2002, P2454, P244A, and P203D. The car runs fine and doesn't show any performance issues, but it feels like it might need a wheel alignment. I'm looking for help understanding what these codes mean and whether they indicate a serious issue or if a simple repair is sufficient.
