Hi all,

First post with my shiny new VCDS cable!

My car runs/works fine as far as I can tell, but when I did a scan, I noticed an error on the rear HVAC.

At first, I thought it was a faulty motor, so bought x2 more 2nd hand ones - still showing the error.
Swapped the left motor (which seems to have no error on it over and - still showing the error.

I've tried to do a basic setting, but when I do the flap adjust, it runs for a few seconds (I can see/hear BOTH rear flaps moving) and then instead of ending with 'successful', it ends with 'unknown'.

The system does appear to work, but I don't want errors on my car.

:-)

Any help greatly appreciated!

Thanks,

Now onto the full auto scan:

Anyone?

Really would appreciate any suggestions/help...

I could buy a whole new rear duct and replacement motors from a scrapped car, but they are like £100GBP so seems excessive if it's not something that I know will fix it.

:(

Have you attempted to perform basic setting on the module? I don't know what the procedure is but that's what I would think the car is looking for by that error message.

Common fault on the 4G platform for the rear hvac motor gears to get stripped. Pull the rear vent out and have a look at the gears to check if they are all still intact.

Thanks for the replies...

This is what is confusing me... I've pulled the rear vent out (so I can see the vent flaps, but the vent is still connected).
I've tried to run basic settings and whilst running, I can see the vent flaps moving quite easily/freely, but instead of saying 'Complete', I get a status of 'Unknown' for the outcome of Vent flap calibration.

As it can't seem to complete the basic setting, I can't get rid of the 'basic settings' error, but can't see/hear any creaking/groaning/stuck flaps.

What does it mean when it gives a status of 'Unknown' for basic settings on VCDS?

Thanks,

Those sorts of status messages come directly from the control module. In this case, I would take it to mean that the control module was unable to complete the requested procedure (the Basic Setting) successfully, and doesn't know why it was unable.

Isn't there a potentiometer that provides feedback of the flap position?

If the feedback from this isn't getting back to the module then the flap position would be flagged as unknown.

Worth checking the WD and then checking the appropriate connections I would suggest.
