I have the above mentioned vehicle which runs on petrol and when I turn on the heater in non-econ mode it starts knocking in the engine compartment sounds a bit like a diesel black cab. I am getting tonnes of suggestions like it is the heater blower motor or it is th air con compressor or its the clutch on the A/C compressor. I am confused. When heater is switched on in econ mode the problem resolves. The problem exists with hot and cold engine.
have the same problem?
