Hi guys, my heater on my 90 8v gti has never worked properly since owning it, but now with the colder weather coming i've decided to tackle the problem. On starting the temp gauge never climbs above 1/4 at most and when moving off will sit just above the red, although it will rise to between 1/4 and 1/2 on the gauge when idling. The heater blows out some warm air initially, then goes luke warm to cold when moving. I have flushed the system out, changed thermosat, and bypassed pressure release valves( removed them). Could the problem be heater matrix?.
Many thanks
Shaun
