    hi have a 54 plate a4 2.0 tdi air con works fine but when i put it on to hot or hi it blows cool air its warm for about 5 seconds then goes cold , temp gage stays at 90 noticed fan on all the time, took fan fuse out today still ran at 90 and heating did not get any hotter , could it be air in the system or something other not losing water or anything like that

    Welcome to the ' A4 not blowing warm air' club , I am in the middle of a similar situation but mine is intermittent hot air, difference is i may have a leaky thermostat so i am starting there.

    First of all check the matrix hoses going through the bulkhead and see if they are both getting hot, that will rule out a blocked matrix
    You could also try bleeding the system of air, if you search the forum you should find a few post on how to do this

    Good luck
