still got cold heaters... please help
ok so i got told this could be a problem with the heater matrix so i took it out, cleaned it thoroughly until it was getting hot all over and put it back in
thought it may be an airlock so continued to bleed system through and still nothing.... until....whilst engine was running i undid the cap to see how much pressure was in the system and low and behold... HEAT!
But when u tighten the cap back on it goes cool again, i am completely stumped...
also just tried the ATC diagnostics check and came up with no fault codes
any help would be greatly appreciated
