While my car is off the road I thought I'd investigate the weak heater output before it gets too hot to test it.
The heater in my Plus Four resolutely refuses to blow hot air until the engine has run for at least 5 minutes, and then only when at high revs. Allowing the engine to idle cuts the heat almost instantly; almost as if there is some valve redirecting coolant from the heater matrix elsewhere. Are other owners seeing similar properties? My dealer has helpfully explained that TADTS.
