Golf 3: Location of the pressure relief valve.

Hi,

Yesterday, I was able to read an error code in the diagnostic memory of my climate control system (even though it seems to be working perfectly): 'Defective servo motor for the airflow control flap, V71.'

Where is this located? I thought it might be the recirculation flap, but that's not driven by a motor and actually seems to be working fine.

Can someone help me with this?

Hi,
The pressure relief valve is the uppermost valve located directly below the pollen filter.
According to the SSP208, the air recirculation flap and the back pressure valve are moved by an actuator. In the G3, this is achieved using vacuum, as I observed today.


Best regards, Andy.
