Hi all our A6 has an issue with the passenger side dashboard air vent doesn't blow any hot or cold air on my setting or speed. All other vents work fine

 

Any one any ideas 

 

Thanks again any advice greatly appreciated

I believe there is a motorised flap for each vent so I guess that one is defective. Wait for others to confirm my opinion before doing anything.

I believe Cliff could well be right. 

Update so removed gloves box all actuators seem to be working meaning the little star shaped hole is moving however the middle flaps not moving. On video you can all holes move the bottom feet flap moves but the middle doesn't 

 

 

So is that still actuators fault? And is it the middle one then that needs chant

 

Thanks

You'll need to replace it. 

The middle one? Maybe done something stupid but the flap for the middle one try pushing it with my finger not broken it but it's come off so basically now when I turn the heater on that vent is working.

It's cowboy cheap fix literally there is no flap there for the actuator to close and open so happy days lol

If you scan the car with VCDS it will identify if an actuator flap is faulty. Sometimes it’s mechanical, as in the nylon teeth on the actuator flap that the little electric motor drives is broken, or the motor itself is damaged. Of course it’s usually buried deep in the dash. VCDS will identify module, and from there you can search YouTube for disassembly. Usually involves removing glovebox, trim and contorting yourself in an awkward position to access.

When got car the heater was messed turned out to be coolant control valve under windscreen. But before that we thought it was heater matrix so changed that. Think in that process maybe when reassembling the actuators may e may have messaged the arms or something or the actuator itself. (Was sumer so maybe actuator messed up prior to changing matrix but didn't notice)

 

Got heat from the vent now so all good . Agree due to awkward location think we'll keep it with the flap removed so no long awkward fiddly job.....until get tempted to do it properly lol

 

thanks all genuinely appreciate the advice and help
