Thanks for the reply. I haven't checked the sensor plug myself. Where is it located, and is it easy to access? I don't have the exact error code right now, but I can get it from the car diagnostics printout. I'll check the plug connection myself.

The water sensor is usually located near the fuel filter. It isn't too difficult to get to, but you might need to remove some covers or hoses. If you're not comfortable with electrical work, it might be best to take it to a workshop. It could be something simple, but you don't want to make it worse.

Thanks for the advice. I took it to a mechanic. It was a corroded plug connection, like we suspected. They cleaned it and charged me 95€, which is better than replacing the whole sensor. I appreciate your help pointing me in the right direction.

I had a similar problem with my CLK. Same symptoms, check engine light and everything. It could be a faulty connection like you suspect. Have you checked the sensor plug for corrosion or damage? Also, what's the exact error code you're getting?
