Skoda Superb Radar Sensor Issue

My 2001 Skoda Superb with a diesel engine is giving me some headaches. The radar sensor seems to have stopped working. I'm getting an error message in the speedometer, and there's an error stored in the error memory. This is causing all sorts of systems to fail, and the warning light is on. I suspect the sensor is dirty. Any ideas?

Summary of the thread

A 2001 Skoda Superb with a diesel engine was experiencing issues with a non-functional radar sensor, leading to system failures and warning lights. The suspected cause was a dirty sensor, which was confirmed after cleaning resolved the problem. It was suggested that if the issue persisted, professional calibration might be necessary, as it requires specialized equipment.

Oh dear, a Skoda Superb with a radar malfunction. These electronic issues can be a real headache. When you mention 'error memory,' are you referring to the diagnostic trouble codes (DTCs) that a scan tool would pull? Knowing the specific code would be immensely helpful. Have you tried checking the radar sensor itself for any obvious damage or obstructions? These automotive sensors are quite sensitive, and even a little bit of grime can throw them off. Radar calibration can also be tricky. What exactly were you doing before this error message first appeared?

Thanks for the quick reply. Yes, I meant the DTCs. I haven't checked the sensor itself yet. Where exactly is it located, and is it easy to access? Also, what do you mean by 'radar calibration'? Is that something I can do myself, or does it require special equipment?

Alright, let's clarify a few things. The radar sensor is usually located in the front grille or bumper, behind a plastic cover. Accessing it might require removing some trim pieces, but it's generally not too difficult. As for radar calibration, it's the process of precisely aligning the sensor so it can accurately detect objects. If the sensor is even slightly misaligned, it can cause errors. Sadly, it typically requires specialized equipment and software that only a workshop will have. Given that you're experiencing multiple system failures, it's best to get it checked by professionals. It could be a simple fix, but without the right tools, you're just guessing. Don't risk making it worse.

Turns out the radar sensor was just dirty. I cleaned it myself, and everything is working again. Cost me 45€ for the cleaning supplies. Thanks for the help.
