Mercedes GLA Diesel Engine Error Messages

Sounds familiar! I had a similar issue with my GLA, though I can't remember the exact year. The engine light came on, and the car threw a fit with error messages all over the place. Did you check the control module? Sometimes a simple reset does the trick. It might be worth investigating before you panic!

Thanks for the quick reply! When you say 'reset', do you mean just clear the error memory with the diagnostic scanner? I did that, but the errors came back almost immediately.

Ah, right. If the codes came back straight away, then just resetting won't fix it. In my case, the coding of the vehicle was incorrect, so the system wasn't communicating properly. It was an annoying issue. I'd suggest taking it to a workshop that knows Mercedes. They'll probably need to recode something.

Thanks for the advice. I took it to a workshop, and you were spot on. The coding was messed up. They recoded the control module, and the errors are gone. Cost me 360€, but at least it's sorted. Appreciate the help!
