V50 Heater Blowing Lukewarm Air

I've got a V50 too, and I had similar heating issues last winter. Ended up being something to do with a valve in the cooling system. Was the error code anything specific, or just a generic code about the cooling?

The code was something about the valve circuit being faulty. He said the likely cause is a defective cable or plug connection. Did yours throw a similar code? How much did it sting you?

Yeah, sounds like the same thing. I fiddled around with it for a bit, but honestly, I'm not great with electrics. Bit the bullet and took it to a shop. They sorted it quick enough and saved me a load of hassle. I'd recommend getting it checked out professionally, especially if it's throwing error codes.

Makes sense. Appreciate the advice! It was the water valve like you said. Workshop diagnosed it straight away – defective valve with a corroded connector. 95€ all in. Thanks again for your help!
