Hi guys, just joined the forum.

I have a coolant leak on my 2008 a4 looks like it may be coming from a little hole in the video, although not sure. Does anybody know what this is?

Is your coolant level dropping?

I'd start buy giving the whole area a good clean, that could just be collecting water from somewhere else and then corroding a steel screw as your coolant should not be rust coloured.

Once it's all clean I'd run it up nice and hot and have a feel about for leaks.

Yeah the level is dropping slowly. I cleaned it up this morning to see if I could find the source. The car had been out of use for a couple of months so the rust I think is just where the coolant has been corroding the bolt. I just wonderd what the plastic thing is, a water pump?
