CLIMATE CONTROL AIR FLOW IRREGULAR
The flow of air sent by the fan in the passenger compartment using the manual speed control is not sufficient; it does not correspond to the speed set.
The networks go on stand-by 30 mins after the engine is switched off. This makes it impossible to carry out the fault diagnosis. If a diagnostic session has to be opened, start up the engine to reawaken the networks.
