- in this video, I will identify the various HVAC air distribution flap motors on a 2015 Audi A3, which is common to a Mark 7, 2015 and newer VW Golf.
Several HVAC module fault codes will require replacement of these flap motors:
B1091 13
B1091 54
B1091 71
B1090 13
B1090 54
B1090 71
Old part numbers:
5Q0907511A: Front air distribution flap
5Q0907511D: Defrost flap
New part numbers (from VW):
2Q0907511G: Front air distribution flap
5WA907511B: Defrost flap
Great video that I sadly only found now, after repairing my car.
Notes to others who find this before starting the repair:
- You don't need to remove the Instrument Cluster
- On a LHD vehicle, you have to remove the driver footwell airbag to get up to the distribution flap motor. If you don't want to disconnect its electical connector, just put it on the brake pedal
- for getting the screws out, use a bit that's as magnetic as possible on a ratchet. Saves you from losing screws in there.
- for getting the screws back in, use a bit of tape to fix them to the bit, that way you can't lose them but you can just pull to "unstick" them once you have them screwed in some threads deep
Dude, exactly the information I was looking for!! Thank you
Just bought a used A3 the other day and realized this is a problem. Thanks for the video, super helpful!
Thanks. Currenty have temp problems on my MK7 golf on the drivers side. What you pointed out for the temperature control is probably what I will need to replace. Looks like that is in a better spot for removal. (Research continues)
Thanks you for the information, best explanation video out there! Had to also do it for mk7 Golf, because the aircon was not blowing air to the footwell. Part number was 5Q0907511A but was also advised to use 2Q0907511G and OEM part because cheaper parts can be risky. Did not need to remove the instrument cluster, but the two screws took a nice hour to get out. The lower one can be done with a smaller hex screwdriver and the top one I did with a regular screwdriver with hex head, just have to figure out the right space to put it through.
Good video thank you! 🙏
i’ve got an a3 that doesn’t blow warm air at all, checked heater matrix and that’s all okay, so would you say it’s possible that my problem could be with the flaps/motors or with the control unit itself?
Thanks for the video. So i have codes B109071 defroster flap, B108B13 & B108B71 fresh air recirculation flap motor. These if i understand you correctly are right side behind glovebox. top one center area and one far to the right on the flap door above fresh air filter? is this correct? same car. Looks like part # 5Q0907511d is now 5WA907511B. I get air all the time out the defrost front window and can get air out the vents but still defrost vents if i only have vent button on. never get air out foot area no matter what switches are on. I can turn vent air flow off but always getting air out defrost no matter what.
You are correct: Both are behind the airbox. The defroster flap motor is the upper flap motor on the right side of the HVAC box in the center of the vehicle. The recirculation flap motor is above the cabin filter, far right side.
Great video, thanks for posting this in such detail! 🙏🏼
For a UK (RHD) car, my error code is “328964 - Motor for Front Air Distribution Flap B1091 71 [008]”
I’m a little confused but does this mean the faulty motor is the lower one near the footwell on my driver (right) side?
The front air distribution flap motor on LHD vehicles is on the left side, upper motor (behind instrument cluster). It's the hardest one to get to. On your RHD car, I'm almost certain it's in the same spot, thus in your case, and based on your fault code, it'll be behind your glove box, close to the top.
The two lower motors are for driver and passenger temperature control only; one on the left side of the air box and the other on the right side. These are the easiest to get to.
@@biturboaudis4 Thank you for the quick reply!
I understand what you’re saying and that makes perfect sense 👍🏼
The weird thing however, is that regardless of the fault code, my problem is the temperature control on the right side (my driver side) is not working. I only get cold air from the vents on this side of the car. Other side is fine 🤷🏽♂️
Which would suggest I need to change the lower (easier!) motor….
Hence my confusion
What controls the middle vents? The only vent that blows is the driver side vent by the door and on the passenger side one as well.
The front air distribution flap motor controls that airflow. It's the hardest one to get to, left side, upper.
@@biturboaudis4 thank you
I moved the flap (without motor) to see if it was stuck... By looking at the new motor incould see that it isnt symmetrical, so would that mean that you cant put the motor badly on the gear of the flap?
Thanks for your answer👌👍
Yeah, the motors and shafts are asymetrical to avoid misalignment. Though the adaptation procedure for the replacement calibrates the end stops, so...
Repaired! Thanks for your help mate @@werdck3321
Can you please tell me how to align the gears of the motor and the flap? Did you do it by hand?
Yes, I aligned them by hand. One needs to take note of the position of the old motor upon removal, then the new motor can be actuated, by plugging it in without mounting it, so that it matches the position of the old motor. As a matter of fact, when I replaced the first flap motor, I didn't have the teeth lined up properly, and as a result the motor skipped a tooth on the gear when I actuated it. It was fine after that.
Seems like this is an up and coming problem, read a few recent comments and have a problem myself (defrost actuator) in my 2015 A3 : |
Hey ive got a right hand drive vw passat. Will the defroster flap motor still be on the right hand side, in my case the drivers side? Cheers
Before making this video, I watched another video from someone in the UK and from what I gathered, yes, the flap motors on the HVAC unit (except the recirculation flap motor) are in the same spot on the RHD cars.
Do you happen to have the part numbers for all 5 motors?
Sorry, I do not. Anyone at a dealership should be able to get those for you, or even an online ETKA parts catalogue.
What tools did you use to get in that tight space?
I used a 1/4" drive palm ratchet (little round thing) with a T25 torx bit on it, and a 4" extension because it's a bit of a far reach for the top bolt.
Could you do a walk through of how you removed the instrument cluster?
@@MikeBrown-rr9wj There is a cover on top of the steering column that has a piece of vinyl fabric on it. That cover/piece is clipped into the bottom of the cluster and needs to be pulled towards the rear of the vehicle, which exposes two screws that secure the cluster to the dashboard. Once those two screws are removed, the cluster can come out.
@biturboaudis4 Thank you for the insight. I'm going to tackle this project this weekend. Are there any tips on disconnecting the motor from the flap arm (or whatever is connected to the motor)? In other videos, I saw a yellow arm or pulley system. Did you disconnect the battery, like I usually do when working on cars? Sorry for the barrage of questions. I'm just trying to get a leg up on the job.
@@MikeBrown-rr9wj I did not disconnect the battery, but it was a bit of a PITA to align the new motor to the flap position. I had to adjust the flap's position more times than I want to admit before the new actuator lined up properly.

They make cars so shit nowadays! You’d think Audi are well made because of their price but fuck me, they make everything cheap
