Hi folks!

147 dual zone climate control blows too warm air for the driver. Also, there's a silent continuing tick-tick-tick once per second all the time and I think it comes from the air vents.

Multiecuscan displays the sensor information above. Both sides are set as 19C.

So, is there something jammed in the climate control system or what?

Best regards,

try a reset. Done by;
- disconnect negative lead battery for 15 minutes or so
- reconnect
- switch on ignition (don't start), and wait for a couple of minutes for all audible activity of moving heater flaps stop
This should reinitialise the position of the stepper motors.

Also won't hurt to blow out (with vacuumcleaner or compressed air) the interior heating sensor, mounted behind the small grill in the centre console...

it's normal that the treated air temp will differ from the set temp, as the system tries to achieve the set temp as quickly and efficiently as possible.....

there is no sensor for treated temp right, so it's correct MES displays no value for this

Thanks for the advice. Altought all of the above is already done. Resetting is done as well as cleaning the temperature sensor.

In MES you can also test/activate the mixing flaps, to see if they work correctly ....
