Av tried to bleed the air lock out like it says via videos let it run with the tap open heat was coming through car got warmed up then put thr cap back on and heating went bwck to cold again av spent around700 on thr car now am just fed up with it 1 thing after another lol

Yeah its a 1.9tdi the Pd engine in a Audi A3 every garage a go to literally say a different think most say head is gone but there is only loosing coolant sign no smoke for exhaust or overheating just comes on every few days or so to check coolant

Keeps at 90 no smoke from back but coolent has to be going somewhere and someome from a garage said only thing he can think is a cracked head or on its way out it popped up check level went over the 90 yesterday withing 10 seconds went back to 90 and light went off car has me head all over lol

Just a quick 1 got speaking to a guy from a. Garage the day and he said it's possible a would have a crack on the head but there is no smoke coming from the back or over heating could that still be the case ?

Ah smashing I have done everything apart from that going to give the engine a flush and get this fitted next weekend and pray it works its the pd engine people say there bomb proof am really doubting it now lol

Hi Steve is that the thermostat housing your on about a was talking to a lad he said could be that matrix heater or have a air lock in the system and to flush it as heating comes on hot then cold... But yeah someone did say that the thermostat could be staying open rather then open/close

Hi all new here.. My head is totally gone so was loosing coolant without any leaks visible had a new belt and pump fitted was working great for a week and seems to go again had a new seal popped on the expansion tank was ok for a day or so then came back up on screen we have had a pressure test no signs of leaks when I open the the expansion tank the pressure brings the coolant straight back up also had a head gasket test and stayed the same colour no over heating am all out of options any help would be great
