Seat Arosa Diesel Engine Trouble

I'm pulling my hair out here. My 2004 Seat Arosa, diesel engine, is playing up. The check engine light is on and the engine's running rough. I scanned it and it's throwing a water sensor error. My code reader suggests it's a bad cable or plug. Anyone had this?

Summary of the thread

After checking the wiring and connections, it was resolved by cleaning a faulty connection, which cleared the error codes.

Sounds like a sensor fault alright. The malfunction indicator lamp (that's the check engine light) is a pain. Have you checked the wiring to the water sensor? Sometimes it's just a loose plug.

Yeah, I had a quick look, but I'm no auto electronics whiz. Where exactly should I be looking for the water sensor plug? And what am I looking for, exactly? Like, corrosion? Loose wires?

Okay, if your reader is pointing at a connection issue, and you're not comfortable digging too deep into the auto electronics, it might be worth getting a garage to take a peek. Electrical faults can be tricky. At least you have a clue what's up.

Just to let you know, I got it sorted. It was a dodgy connection. The garage cleaned it up and all the error codes are gone. Cost me 95€, which I reckon is alright. Thanks for the help.
