My 2019 Mercedes GLE with a gasoline engine is throwing errors The onboard diagnostics shows a fault and I'm experiencing an electrical malfunction The navigation system is dead Could this be a software issue Has anyone else experienced this I suspect the control unit programming is implausible A software reset maybe The repair cost is 240€ Any advice on getting this control module sorted

I think I had a similar issue with my GLE, although I can't remember the exact error codes. The navigation went haywire and the electrical system was acting strangely. Did you recently have any work done on the car, or any software changes?

No recent work or changes That's baffling It just started happening Was your issue also related to a faulty control unit, and was a software reset all it needed

Mine was a software glitch in the control module. They tried a software reset first, but it didn't completely fix it. They ended up having to re-flash the entire control unit. I'd recommend taking it to a workshop with experience in Mercedes onboard diagnostics. They'll be able to pinpoint the issue and re-program the control unit if necessary.

That's exactly the kind of info I was hoping for. Knowing that a simple reset might not cut it is super helpful. I'll definitely take it to a reputable workshop and mention the possibility of re-flashing the control unit. Just got it back from the workshop. They confirmed it was indeed a software malfunction and re-flashed the control unit. Everything seems to be working perfectly now Thanks again
