- Audi A6 C7/4G rear HVAC (Climatronic / AirConditioning) flap motor/actuator replacement.
Noticed, that there is no air coming out of the rear right side vent tunnel. VCDS showed few errors:
Address 28: HVAC, Rear (E265)
0033 - Motor for Rear Right Upper Body Vent
0070 - Position Sensor in Rear Right Upper Body Vent
I disassembled the whole rear Climatronic pane to see the right flap is not moving. Also noticed some broken plastic parts in that shaft. Got my hands on cheap shaft with booth flap motors so decided to change the whole thing.
Easy to replace, 10min job.
You need to perform the start/stop flap position adjustment via VCDS - HVAC Basic settings (rear in this case). Works without it too but I had the chance to do it and also get rid of the errors in scan.
My motors (actuators) had the P/N: HEUT0045K or ZBAT0052D02
(but I had seen the same parts under different P/N)
I've decided to make this video because there is no other on UA-cam (at least not in EN language/subtitles)
PS: I was talking about different connectors for the grill vent piece that I changed.
Same P/N, different connector that wont fit
See this: ibb.co/YWSGQ7W and ibb.co/RB24kTY
So be sure that you order the one you really need when replacing the damaged vent grill piece - Авто та транспорт

Thanks for the video. For my A6 C7 2013 had to buy new actuator from Audi. Right flap was totally twisted/broken. Whole unit code 4G0857042D. I as told that this is 2015 model and the only available for my car. Car system did not find the actuator motors so in VCDS I did: 28-HVAC , Rear ---> Basic settings - 04 ---> choose from drop list: IDE01549-Automatic addressing LIN 1 ---> Go! After that the originally mentioned IDE1546-Adapt door end step did work out. Without that address operation I got malfuction error message from VCDS.
Thank you for such a nice video with comments. Now I will try to do it myself too as I am getting exactly same fault codes on vcds as you have mentioned in the beginning of this video.
Thank you for this video! Gave me the confidence to replace mine tonight.
Thank u so much! I had only the air issue cuz of the gate was broken and blocked the air.. i just removed the gate so now its also cold in the backside 😁 but this was a very helpful video!
Thank you for your video, it helped me a lot. I just disconnected the 2 motors, works for me 🙂. they made bad noise like a sheep 😀
Great video! Have the same issue.. now to find motors or parts....
Super!
Hi,where did you get the new vent flaps actuators with the motors from?
Would you recommend replacing the entire duct unit or can you replace individual motors too? Both seem to be for sale online, though the whole unit is more more rare and much more expensive.
Hello,
if you only have a faulty actuator, replace part only. As you could see in my video, I also noticed some flap damage inside the duct. So, without that damage, I would also only change the actuator. In my case, I found a whole duct (with booth working actuators) from some wrecked A6 for few euros, no brainer.
@@staman_81 Makes sense. I assume these motors just fit left or right? No need to buy them specific for each side?
@@sinoperture From what I recall, it was the same P/N. Replace it and try.. PS: I did the flap alignment using VCDS after the replacement
@@staman_81 OK parts arrived.... time to put them in. Then need to find a mate with VCDS as I sold my cable years ago when I sold my then Audi to buy a Porsche. Unfortunately having kids has sent me back down the car ladder. :-(. I retrofitted CarPlay the other day so this should be much easier I hope.
Where did you get the new air duct with actuator motors
It comes from wrecked A6 .. local garage nearby. I'm not sure from what country are you, you might check the Allegro.pl or some other second hand dealers
@@staman_81 okay thank very much, excellent video.
Where did you purchase your parts from
As I wrote in previous comments, I get mine here on local wrack-yard for a very reasonable amount.
Servomotor 4H0 820 511 C
Or for the full vent 4G0 857 042 B
Is that a question? I explained everything under the video describtion
@@staman_81 no question friend. This is the actual part numbers from audi for anyone looking for these parts. thanks
@@gerrardalamat9072 It was already asked somewhere in the comments bellow but OK, thank you :)
You mention about two different connectors sold under the same part number. How do you specify the correct connectors when ordering the new part to get the correct one for your car? From what I see on any of the Audi sites you don't get to choose a particular connector. Also the part is up to a revision "D" now so perhaps they have made some improvements, so the same issue does not keep happening!
I have no clue .. in my case, i bought a used part from the wrackyard.. I did communicate with the seller and he send me a pictures of the part available.. So I saw that it's the same connector (of course the first time I tried to solve it out, I just ordered the same PN.. fifty/fifty.. received the wrong one :)
5:00 part number?
For my A6 C7 2014 it was 4G0.857.042
You could have printed new flaps on 3D printer for 10$
