I changed the bulb in my Audi's headlights on a wet and miserable day, I now have condensation in the unit that I can't get rid of - does anybody know a technique for clearing this?
I have a tapping sound coming from my 3 way valve. I have changed the body and head and it is still there. I have TRVs all round and the system runs with a pressure relase bypass. I can vary the sound...
