I have an 2006 AUDI 3.0 TDI quattro Avant and yesterday I had the same problem - a REALLY hot air was blowing on the driver's side, as if the HEATING was set to max, but a cooler air blowing on the passenger side, but still not cold enough. Today I did what you did and now it works great! A 15 min work and can save you a lot of $$$ :-) Thanks for the video, man and all the best!
Exactly describes the problem on my A6 which has baffled my mechanic. After a long run these symtoms occur very hot air through both side vents but cooler air through the central vents. Your solution makes much sense and I will try it when i get back to my base. Car is a high miler 113K and otherwise runs very sweet with exellent MPG on a run and flys through emissions testing . Thank you so much for posting this
When I got the chance to look at this the solution described here it fixed the problem. A/C now all singing and dancing blowing lovely cold air. Time taken about 20mins and an easy job for a home mechanic.. Thanks again
Good afternoon I really appreciate your time and patience to share your knowledge and video. I'm in Florida as well, and it's a must to your AC working right. Thanks again
Finally I have some cold air! Thanks! I followed your video completely but now I have the problem that my car doens't blow any hot air anymore when set on a hotter setting... anyone having the same issue?
Worked for me - thanks for video. Took 15 minutes. Mine leaked a lot of pink coolant - easy enough to top up. 3 days in and so far so good. It seems like it's blowing even colder than it was before - the temperature controls are more useful now.
same thing just happened to me with the coolant. now cleaning the pumps and will put them back in tomorrow and hope for the best! will be sure to top off pink coolant as well :)
@@mangomushroom I've had the same problem with mine - I completed the clean on a hot engine and coolant level dropped significantly - did doing the clean on cold engine sort out the issue for you?
I have the same problem. Did what you said but when I got to the last screw, some liquid starting coming out. So I aborted for now. Any thoughts. Thanks
Thanks for sharing. Please tell the viewers what year/model your car is. I have a 2005 A6 Quattro and it looks different under the hood. Gotta check component location...
This is for the engine mostly, to fix the A/C goto Walmart and buy this EZ Chill R-134a Auto AC Recharge Kit with Leak Sealer Plus - 18 OZ, and attach the hose to the aluminum pipe and pump the ac fuel back into the pipe. Do this while your car is on and heat on at full blast. Thank me later 😊
I asked the tech at the Audi dealership, and he said it is located on the passenger side under the dash (dash has to be removed). I haven't attempted to do the fix yet, so I am not sure exactly where it is located.

Hi mate I have a 2003 Audi a4 1.8T convertible and my Econ light was on since I had the car, so decided to give it a diagnostic and it told me to replace the high pressure sensor, so I did, the light has gone out now but the air comes out cold but not colder than what it has always been. Before i changed the sensor i took it to the garage and they refilled it but didn't charge me bc the econ light never went out. So don't know if they took the refrigerant back out? Do you have any ideas? Cheers
so i have a Audi allroad that the ECON wont shut off also i but the temperature to the lowest and check the compressor and the compressor runs and if i turn off the ac it turns off but the car keeps blowing hot or ambient air, also checked the refrigerant and is good, can this be the issue?
if there is no air blowing, its the blower motor. its the most complicated thing to fix i swear. it took 6 hours yesterday to try and replace it, and i failed, cracked my glass, and almost broke a cover lol
What can anyone say about the following.. My car blows hot at like any temp before reaching working engine temp (90C) then It blows hot at 21,5C and up. If you go lower than that it just blows cold 🤔 ac works fine in the summertime
When I opened my pump it was filled with coolant fluid. It drained out. Clean the pumps but still not cooling put the pumps back now having coolant leak. But the pumps was dirty and I clean them.
I've had the same problem with mine - I completed the clean on a hot engine and coolant level dropped significantly - did doing the clean on cold engine sort out the issue for you?
As I begin to remove the metal covers, I get fluid (coolant I guess) forcing its way out. Is that because the engine is still warm? So does the engine need to be stone cold before doing this? Thanks.
@@TheRealMeCoWhy Many thanks for getting back to me. Weirdly even the light lifting of the metal covers and some coolant leaking out then closing them down again has got it all working again so looks like it is def the culprit. Will give it all a good clean tomorrow and hope for the best. Thanks for saving me the £££££££. !

For the a4 look at the ac line right under the hood by the passenger side one is hot and other is cold .The cold one has a big bolt open it up in side the cold air line there a ourfist tube change it cost about 20 dollars that should work.
I have 2007 A3... no cold air for first 5~8 minutes, then it starts. I had the control switch replaced (it was leaking) and the system recharged. Doesn't seem to have any leaks (no dye). How does this HVAC pump interface with the system, if it can be removed without compromising the refrigerant closed system?
The HVAC pump is separate from the AC refrigerant system. The refrigerant will not escape. Unfortunately I do not think 2007 Audi A3 uses HVAC pump similar to the one in video (if at all). It sounds to me though that you may have a different problem (electrical, relay, amount of refrigerant, temp sensors, etc). I recommend taking it to a knowledgeable mechanic.
I first took it to the dealer... or I should say "stealership." To diagnose the system, they said they'd have to purge and recharge the system. In the end, they told me what I already suspected--the compressor needs to be replaced, and I had to pay $300 for that "confirmation." Then the estimate? $2,100. Absurd. Never again. I went to a reputable local shop and they'll do the A/C compressor plus condenser with all labor for $900.
sorry to hear that :( 2007 A3, is that the 2.0T engine? I never replaced the compressor on that motor but I did on the 1.8T and it was super easy. Used compressors usually run around $100 if you are handy enough to do it yourself I would say - give it a try. I am just DIY type of a person.
Yep, the peppy 2.0T with DSG trans. Very fun to drive. Nearly as nimble as my old TT. I'm very handy and have worked on previous cars I've owned when time permitted. But A/C is completely unknown to me. Dealing with refrigerant scares me... so I figured best to have it taken care of and it should be my last time. Given what I had to sink into it for the 80k service and timing belt replacement, I'm gonna stick with this car for at least a few more years. Drove a loaner 2017 A3 S-line and was wowed. Somehow felt a bit cramped, though.
The timing belt on those cars is a must have service. I have done 2 x 1.8t and 3.0. The 2.0t (fsi belt and tfsi timing chain) seem pretty easy too. AC is simple, just a matter to recycle the old refrigerant. Have you ever checked the cam follower? $20 or $30 part that tends to fail on the 2.0t engines and may cause massive damage to the motor. Where are you located? I dont mind lending a hand if you are local ;)
Hmmm... my 2006 Audi A6 a/c not working, but I can control hot air. My a/c slowly died, not suddenly. So I don't think it was compressor. Could this video be the solution? Also, what is the dirt on the metal spindle called? Is that corrosion/rust? Will WD40 work to remove it? Thanks for posting this video.
