I'm surprised that so many of the flap motors are showing mechanical faults!!! The mechanic should clear all the faults and then drive the car for a bit, try all the air-con/climate control settings and see if the errors reappear! If the faults do reappear, then maybe another specialist maybe able to assist

Officially going by the book, the dash has to come out, but it can be done without it!!! There is a youtube video of someone replacing the flap motor by removing just the lower part of the dash and the side of the side console. It's a bit awkward to bend down and get access but it can be done. I think there is another flap motor that needs to be removed before you can get access to the other flap motor. I showed my Audi specialist the video and he managed to do it. I think it cost around £450 all in. The genuine Audi part was around £100, but i'm sure you can get a cheaper copy part. I don't think you can recalibrate the part via a panel button sequence. You need an OBD2 scanner that has the 'Basic Reset' function to do this.

Cool. Maybe the warning will clear after enough cycles. If the ABS system is bricked, don't be too alarmed. Although it's not ideal, you can send off the ABS unit to a company that resets it for a fraction of the cost of a new unit (around £3-400). I posted the link to the company in an earlier post in this thread (go back a few pages). You'll need a mechanic to remove the part though, so you'll be without use of the car until it's put back on....

Does the brakes feel any different?

It sounds like the warning that the 'brake pads' are wearing thin is a separate issue. If you at least get the pads checked and replaced if necessary first, then see if that light goes out and go from there

£300!!!!! That is an absolute rip-off!!!! I paid approximately £90 for the OEM part from Audi and swapped it myself in 2 minutes! From my memory, I can remember if the warning message on the dash cleared straightaway without clearing the code with my scanner. Is there still a warning message on the dash? I don't recall the brake light staying on as being a symptom

Not sure on the A3 im afraid. Maybe someone else can be of more help....

Good to hear! :)

Ignore the message that says it's 'OK to drive'!!!!! The message is incorrect!!! DO NOT DRIVE ANY FURTHER (try not to brake too hard and park up as as soon as possible where safe to do so). Buy the required sensor and replace it asap.

I agree, it could be a dodgy sensor. If you do get the red warning light, the ABS unit will be bricked!!! It will cost thousands of £'s to replace! HOWEVER, the good news is that there are companies that can rese tthe unit at a fraction of the cost (still hundreds of £'s and you need a mechanic to remove the part so you can send it off). Please see one of my posts earlier in the thread for one such company that offers this service (I have no affiliation)

I also bought mine from a main dealer, as I wasn't sure if I could trust a chinese copy (can save save £80 if it works, but could potentially lose £3k+ if it failed). By the sounds of most people's experiences, the generic parts seem to be ok

Glad to hear you got it sorted Flatspell. To be fair, unless the garage specialise in Audi's, they may not know about this specific issue. They'll just replace the part that's likely to be the issue after a diagnosis scan.

Ouch, that's made your wallet lighter. At least the ABS module wasn't bricked! Any idea how the wiring loom got fried?

Regarding the Brake Servo restricted warning light - if you haven't replaced the sensor, DO NOT DRIVE IT!!! The braking may feel normal, but you run the risk of triggering the ABS cycles enough times that it will brick the ABS, leaving you with a VERY BIG bill! Just buy the replacement sensor (OEM or an aftermarket) asap and fit it yourself - it's dead easy to do (1/2 minute job)!
