AC problem w/ code

[A4twin]

vag the car b/c ac doesn't blow cold air until i put it on "low".
got this fault code:
01274 - Air Flow Flap Positioning Motor (V71)
41-10 - Blocked or No Voltage - Intermittent
TIA

[CO AVANT]

erase the code and see if it comes back. Unplug the electrical connection to the ac unit with the car on and then plug it back in. You might need an ac recharge from the stealership. If you do that have them put in new expansion valves or clean the current ones with throttle body cleaner spray or similar solution.

thanks

i had that same code, replace the stepper motor, its hella easy, take out the glove box and the stepper motors are right there and accessible, that one is identified by a light blue washer on the linkage.

heres is a pic underneath the glove box, which one is it? thanks

[brewmastr]

in the 2nd pic you took the one on the left.

on the link below is it #14 (Adjust motor Ventilation) thanks

yeah that looks like the one, keep in mind i had no temp. regulation issues, but mine however was making a clicking noise every so often and i had that same exact code.

[A4twin]

thanks, hopefully that fixes it, i get only cold air with the temp set at LOW

[A4twin]

finally got around and changed out motors, i have no codes but still i only get cold (and not very cold at that) air when on "LOW". any help would be appreciated
TIA

[A4twin]

well still having problems with the A/C took it to a mechanic he apparently "cleaned" the system put new coolant and checked for leaks. found no leaks and "everything" is working and no codes, i still only get cold air in the "LO" setting and the air that comes out is not that cold compared to my wifes audi it seems that the air coming out is maybe compared to her 70 degrees i'm getting fustrated now i've spent about 300 bucks now since i've had the car and no fix yet. what can be causing this? is the a/c head unit messed up? please help it's HOT as HELL here in Houston

I have the same code but if I run VAG com and get to HVAC and click on basic settings change the first one from 000 to 001 and it will reset all motor flaps/servo and the code doesn't come back or everything should reset.

My guess is that you need to get to basic settings and reset all motor flaps because the new motor might have gotten the old motor settings.

Keep in mind that once I reset all the AC motor flaps the air is colder then before.

Do you have a VAG com?

[A4twin]

yes i have done this in the past with no luck, i just did it again but i don't think their was any difference in how cold (the lack of) the air came out of the vents

I share your frustration! My a/c isn't reliable at all. I Found if i reset the basic settings it works for a little for me. But i get these codes constantly.

00601 - Potentiometer On Positioning Motor for Central Flap (G112)
30-10 - Open or Short to B+ - Intermittent
01809 - Actuating Motor for Temperature Flap: Left (V158)
41-00 - Blocked or No Voltage
01810 - Actuating Motor for Temperature Flap: Right (V159)
41-10 - Blocked or No Voltage - Intermittent
01842 - Potentiometer/Actuator for Temperature Flap: Right (G221)
30-10 - Open or Short to B+ - Intermittent
01274 - Air Flow Flap Positioning Motor (V71)
41-10 - Blocked or No Voltage - Intermittent
00604 - Potentiometer Positioning Motor for Air Flow Flap (G113)

I noticed if I do the basic settings it goes away and the first code that comes you should replace it. One Audi Tech told me one bad motor can cause others to show bad. I dont think all of the motor flaps are bad but since one is not working its erroring others.

[haroulli]

Which one of those is the 01810 - Actuating Motor for Temperature Flap: Right (V159) ????

[my1stturbo]

I'll be following this thread now. I checked my codes yesterday and had 1809, cleared it and checked again today and now I have 1809 and 1810. Will try the basic setting in the morning and see if that helps.

Bad A/C compressor?

[darkstar]

I share these problem with you guys and the A/C issues i swear my car has the crappiest ac ever! now i talked to my mechanic today and he thinks that the mixing flaps aren't quite closing all the way. we put the gauges on the system to check to see if i was low on freon. that was the case. according to the gauges we should have had approximately 28-32 degrees from the vents i had 40 degrees on the drivers side vents and center passengers i had 55. so no where near where i should be! no he is thinking that the servos aren't quite closing those mixing flaps enough so there is a tiny bit of hot air coming in through the vents. i am mostly having problems with my center vents. does any one have a diagram of the hvac system they can post?


thanks

well, i think i finally fix the problem. i change out the climate control module today (thanks MAT) and so far i get "COLD" air now at 70 when before i would get "COOL" air at 65.

Sorry for the thread necro, but I think I'm having a similar issue:

00601 - Potentiometer On Positioning Motor for Central Flap (G112)
30-10 - Open or Short to Plus - Intermittent
01810 - Actuating Motor for Temperature Flap; Right (V159)
41-10 - Blocked or No Voltage - Intermittent
01274 - Air Flow Flap Positioning Motor (V71)
41-10 - Blocked or No Voltage - Intermittent

Other than my A/C being a bit weak, I'm not having any major problems (yet) with my climate control. I do have this faint whirring motor and clicking sound coming from my center console though. This sound persists even after the car is shut down and key removed.

Does anyone have a part# for the flap motor that needs to be replaced? The trademotion link above no longer appears to work.

[haroulli]

Can't be 100% but i think this is your problem 01810 - Actuating Motor for Temperature Flap; Right (V159)
I had the same issue and i replaced it. However it wasn't the flap that was malfunctioning as it continued. From their the next step was to replace the Climate Control unit however I sold the car before I could get to that.
I also happen to have a spare motor if you want to throw some $$ my way. I'll happy to send it to you.

Necro: Part deux.

00710 - Defroster Flap Positioning Motor (V107)
41-10 - Blocked or No Voltage - Intermittent
01274 - Air Flow Flap Positioning Motor (V71)
41-10 - Blocked or No Voltage - Intermittent

I have the above codes and my symptoms are annoying clicking sounds when the car is running and no heat unless I'm driving at a high RPM. If it's the clicking noise, then I'm assuming the part I need to replace is the one from the OPs second picture. Does anyone have the part number for that? The link he provided doesn't work anymore and searching for "Adjust motor Ventilation" did not yield a part number.

I'll also try messing with block 0 settings in the HVAC section in VAG-COM to see if I can get it work.

Thanks! I wish the website still had a rep system. I hope at the very least this fixes the clicking noise and at best fixes the heat problem.

In case anyone is looking for the part number for the Adjust motor ventilation flap: 8E1820511F (OLD) and 8E1820511M (NEW)

[subversion]

Replaced the vent motor today. It was pretty straightforward. The glove box came off easily enough, but it took some effort to get my ratchet to get the screws off the vent motor since the area for the back screw was tight. On the whole, it's really simple. I tested everything after replacing the motor and the vent flaps opened and closed as, I imagine, they should. I took it for a 15 minute drive and I had consistent heat. I'll monitor for the next week to make sure everything continues to work.

On the downside, I broke what was lift of the plastic hinge on the glove box while examining it and now the right end of the glove box hangs when I open it. I'll have to stop by a shop and pick up a small hinge that I can drill into the glove box.

Pics of my fixed hinge and a better way to fix the glove box than what I, unfortunately, did: http://www.audizine.com/forum/showth...34#post7138334

anybody have any idea which one one is (G220)? im getting the following code but caant figure out which one from the pics above is G220....

01841 - Potentiometer/Actuator for Temperature Flap: Left (G220)
30-10 - Open or Short to B+ - Intermittent
