Peugeot 207 Radar Sensor Failure
Summary of the thread
The radar sensor on a 2009 Peugeot 207 diesel stopped working, displaying an error message and causing failures in other systems. A dirty sensor was suspected as the cause. After consulting with others, it was suggested that water or dirt might interfere with the sensor's function. The issue was resolved by cleaning the sensor, clearing the error codes, and restoring normal operation, confirming that a dirty sensor can indeed cause such problems.

That's interesting! No, I haven't cleaned it recently, but it did rain a lot last week. Could water really mess with the radar sensor like that? If it's just dirty, can I clean it myself, or should I take it to a shop?

Yeah, water definitely caused my issues! It might be worth checking the sensor connections, but honestly, with all those errors popping up, a workshop might be the safest bet. They can properly diagnose it and make sure it's not something more serious.

Thanks for the advice! I took it to a local mechanic, and you were right it was just a dirty sensor! They cleaned it, cleared the error codes, and everything is working fine now. Cost me 45€, which is way better than I was expecting!

I had something similar happen with my old Renault Megane, though it wasn't exactly the same. I had a parking sensor issue that caused a cascade of weird errors. Was your Peugeot recently cleaned, or did you drive through a puddle lately? Maybe that interfered with the sensor.
