Thanks for the writeup, I may just check mine out too as mine only gets a small amount of air in the footwells. Possibly the servo motor is only opening the vent a slight amount.

 

Have you checked whether you can do the output tests with Vagcom?  That should tell you if the flaps can move their full range.

 

Have no VAG Com :-(

Lots but not many of the part numbers cross reference.  Many of the computer modules are the same, servos for the HVAC, Most of the Suspension pieces are the same (although Porsche specs a different bushing hardness but most aftermarket for VW, Audi, Porsche all have the same bushings). 

Would also be interested in. It is diffult to find a match.

Just looked for a servo for the air vents and also a clockspring.

If the part is taken out, it might be easier, because most parts are e.g. from Bosch.

With checking in Ebay, sometimes there is a hint to / from Touareg parts. But not sure if this information is trustful.

For the servo I told, order one used from a Cayenne and a used one from a Amarok. Parts look almost same.

burixxl, you would only remove the glove box if you were working on a RHD car to get at the 3 Servos. On left hand drive it is a tougher job as the HVAC layout doesn't change so it is still the Left side which now makes it more difficult as the Steering column is partially in the way.  If you are getting foggy windows without the A/C running then the right side is where the fresh air Servo is located, it is close to and just above where the Cabin (Pollen) filter goes.

What I figured out so far, that for the middle vents, there is a middle left servo and a middle right servo. Those are on the left and right side, so I have to do both, remove glove box and Steering column space.

I have a LHD Cayenne. Saw some figure for a touareg, where there also removed the complete dash. Is this really needed ?

How mich hours to work on I need to calculate ?

One other major question. There are 6 servo motors in total. Looking at the spare catlog of Porsche, they have all different number, but I do not think, that there are all different ?

And also read in another forum, that a VAG COM tool is needed to set the servo in service mode. Is this mandatory ?

Hi All, I've located the problem, quite simple really apart from the lack of space behind the dash. I located the servos, there are three I could see, and one under the dash controls the recirculation system. one nearest the shifter is the footwell, there’s one a little further up I assume that’s for the face vents or windscreen. In order to access the servos first remove the bottom panel, one torx screw nearest the seat in the centre, then drop the panel down & detach the 12v aux sockets (there’s 2 on mine). Also detach power from the footwell light. Then remove the glove box, very simple just a few screws then is drops away. Then you can see more. If you follow the wires you see the servos, all 3 are the same basic type. 3 screws hold each one on, that’s the more tricky part as they are fiddly, but once the servo is off you can test it. Mine was dead, but once I worked it a little it jumped into life, maybe it was jammed. I them popped the cover off and you can see inside, there’s a little motor in there and a few contacts, I cleaned it all up with contact cleaner lubricated it and reassembled it. Then hey presto I had a blast of air in the footwells. So that’s the first time for 4 years +, and the dash didn’t have to come out, thankfully. If it fails again I'll get a new solenoid, I think now I know I could replace it in 15 minutes. Hope this helps someone else, regards James

Do you have picture of where the servos located ?

So to summarize, basically removing the glove box is enough ? The center console does not need to be touched ?

My problems seems to be the servos vor the middle located vents.

How long does it take approx. to change it ?

What about the sensor on Bank 2 ? Any experience ?
