Hey all. Hope it's ok to ask for a bit of help here?! 

I have a 2018 S4(B9) but have developed a fault with my air con. The code I got was B109207 so believe the motor has gone duff with my air con recirculation flap motor. I do also have another fault code which is B11AF07 "Fresh air door motor mechanical malfunction" but not sure if they are linked but 2 motors failing at the same time would be mighty unlucky.

If I were to buy a new motor and fit it, is there someone in the central Scotland area that can help me recode/activate it using VCDS as my Carly scanner can't do that.  I begrudge going to a main dealer as they charge so much for what I think is a simple job.

Cheers,

Hi I think you will find that a new motor is just plug in and play, as long as it is the same part the control module will just accept that it now works and not register a code again, the motor is just a slave and as long as it accepts a command pulse it should work fine.

Hi Steve, are you sure as there's an older post on this that states the new part (which has now been superseded) needs activated? I'll try and find the link to that and edit this post with it. Cheers for any and all help....

Hi sorry my BAD apparently from2014 on you do actually have to reset all end stop settings for all the motors and then re register the new motor, which will involve VCDS, sorry only a suggestion but if you intend to keep the car it might well be cheaper to buy the single VIN VCDS as should you need to upgrade to multi VIN at a later date all good, I have VCDS and OBDEleven but I could not find that function on it and I am pretty sure them and Carista share the same software

Steve.

Cheers Steve, I'm looking to sell my S4 but want it working fully before doing so. I'd gladly pay someone for their time and skills plus I'd travel to them. Also, it'd give me the chance to see VCDS in use to know whether it would be worth getting in the future as I do have another Audi. Unfortunately my wife's car is not a VAG car.

 

Cheers, Chisy
