Having an issue with a 110tdi 2001 climatronic (actually an elegance but it's identicle re these problems to mk4 golf and they are more common, hence the post here).

when the interior fan is turned OFF, the ac clutch engages. We know this because of the almighty racket from the seized ac pump..... ALSO - when turning the engine off it engages! Why the hell would it do that?

Further to this, the ac fans under the bonnet both run all the time, period. Even when the car is cold. As mentioned above due to ac issue the ac (econ) is never used.

Vag-com only illustrates an issue with the air flap (for recirculating air I guess) no other issues with climatronic.

This all sounds wrong to me - any comments?
