My 2000 Coupe heater always blow hot air. We have done a big strip down - replaced the heater valve and the matrix and checked that all wires and the flap are working properly. But it still blows warm. Any suggestions most welcome. Thanks Rob

Problem solved.
The new heater valve that we fitted (ex Superformance) turns out to be faulty. It is not turning off the hot coolant completely. Temporary fix in place pending replacement part.
