i have a 2007 a3 sportback 1.9tdi and for the last 3 months of ownership everything was great.until 10 days ago when my heater refused to part with any hot air.took it to a garage and they said it could be an airlock or blockage so cooling system was flushed and refilled with coolant.No change.replaced thermostat but still no change.the heater works on all 4 settings and the heatwer matrix is getting hot but still no heat from the vents.can anyone on here help please as its the coldest its ever been and im freezing!!!
