Whoa, that sounds like a mess! I had something similar happen with my Nemo. Is it affecting your adaptive cruise control, by any chance? Because that's how it started for me. The 'error memory' thing is pretty vague, isn't it? What other systems are failing?

Adaptive cruise is indeed inoperative. Other systems affected include emergency brake assist. You mentioned 'similar'. Was the radar sensor the root cause in your case as well?

Yes, it was the radar sensor. At first, I thought it was just a glitch, but the errors kept piling up. I'd recommend getting it checked out at a workshop. It's a safety system, after all. Better safe than sorry!

Confirmed, sensor was indeed dirty. Cleaning resolved the issue. Repair cost: 45€. Thanks for the input.
