Hi Guys, I was wondering if someone could help me out here. I've just bought a 2008 1.9 TDi A4 Avant s-line. I have noticed that there is a very small leak around the thermostat housing area.
It's this metal pipe (second picture arrowed) I think which goes into where the thermostat goes and then into the heating matrix for the inside of the car. I can feel it's a little damp under the pipe and there is a small ledge for it to drip onto so there is a small amount on there.
Can anyone shed some light on this for me to fix/how much it would cost from a dealer to fix?
I don't think it's very serious at the moment because when I unscrew the expansion tank it has got lots of pressure.
