Sam, I haven't had AC in my daily driver VW for 6 years because the shop quoted me $1k to replace my compressor. After watching this video I bought the Control valve from rkx and installed it. It took longer than id like to admit but I finally have cold ac in my car again. Thanks Sam!
_How we survived without it??_ *_You must be young. First... we didn't have complicated cars with 20 computers per car._* THEN, we had these things called, 'old white men', in these locations called, 'garages'. And they had EARS, EYES, and a stunning lack of greed. You'd go there with whatever was ailing, and they'd say... see that, you need to fix it. Go get this part, see if you can put it on, if not, swing by here, and I'll slap it on for $25. I'll let you figure out how we got from there to here.

The good news is, if you had taken the front end off to replace the condenser you would now have to take it all off again to fix the coolant overheating issue. 1 time is better than 2 times.
ooof if unless you're a youtuber there is no excuse for buying an out of warranty audi ... you should just light your money on fire at least then you'd get some warmth from the money
I started seeing the valve problem on GM cars over 30 years ago. The valve reacts to (or is controlled by the ECM in your case) the pressure inside the compressor (the crankcase pressure) to bleed some pressure to increase the swash plate angle, which controls the stroke of those pistons. We called a compressor with this problem a "de-stroked" compressor. I'm glad you got that email to save you all of the hassle.
When you hook up your gauges, make sure to bleed the yellow hose by depressing the schrader valve until refrigerant flows out or you will introduce air into the system.
Wow.... cheers to that young man for saving the day with the valve issue. Once you solve the coolant issue, you're going to have a sweet daily !! Congratulations !!!
to be honest, this is your best one yet. I mean, even having to take the front end off isn't a huge deal with the deal that you got and though it's frustrating, at least you didn't do the ac compressor that way, reassemble it, and five miles down the road need to do it all again.
Best youtuber in this category . Tired of watching others repair cars with free parts. It’s like watching billionares buy brand new Bugattis. AND you’re not only buying BMW’s (unlike others). You’re the goat, Sam ! 🐐
This fix has been known since 2007. I've done few myself on my old 2007 Jetta and VW Bug i used to have. They do go bad quite often and 9/10 times the compressor is fine. These valves are now more common than they used to be. I used to order them from Ali Express.
It's always fun to find a common failure that's garnered a wealth of knowledge on how to fix and or work around it. I had an issue with the EATC on my '03 Mercury grand marquis, the A/C was only blowing out the defrost or the floor. I replaced all the O-rings in the vacuum control matrix or whatever it's called. And was able to fix the problem with under $2 in O-rings, as opposed to $400-500 for a reman EATC unit
Quick tip from the Caribbean, when opening the valve on the can turn it upside down and slowly unscrew the yellow hose from the manifold until you see refrigerant spraying out, then screw it back tight, turn the can valve right side up and commence filling. That way you'll make sure refrigerant is adequately flowing from the can to the manifold and almost all air trapped in the yellow hose will be purged keeping your A/C free of non condensable fluids like moisture or water vapors.

About 90% of the variable compressors that ive seen fail are due to the RCV. The other 10% have been attributed to lack of oil flow from low refrigerant charge. The oil flows through the system with the refrigerant. Ive tried to offer selling a customer the valve. Every shop i have ever worked for has always chosen to replace the compressor, condensor, expansion device, and drier/accumulator. Most techs who do not have a high comprehension of a/c systems do the same. In their eyes it makes more money selling the whole set and you can offer a warranty. I have fixed some comepressors with $3 in parts and it ran perfect for another 70k miles before selling. Having some basic knowledge can help you save time and money.
@@brayannexon4613 Don't blame German engineering. My 04 E46 M3 is still going strong, AC and all. Only thing I ever had to do to this car was oil changes and coolant related stuff as the plastics were common to fail. Other than that, has been absolute dead reliable.

My 21 yr old Honda ac barely works, there is a bag that needs changing. I got the system half or less half working and it's good enough for me in new Zealand....
Sam, three tips that I do while servicing an A/C with Freon. First I bleed just a little Freon on the service hose to empty air and humidity in the line before attaching to the service port. While filling, I bring the engine to 1500 to 2000rpm to charge the system faster. It’s helpful to have two people to do it and before his passing, my dad loved to cup the Freon can in his hands and slosh the Freon around to warm the can and accelerate the transfer. Boy, I sure miss him. 🖖🏼
Surely something didn't break every month. How can cars be that fragile unless your roads are as bad as we have in NYC. It's no wonder that they say cars keep most Americans broke. Best of luck going forward with repairs needed only twice a year.

2 Tips for you in this situation DYI. Tip #1- Always make sure that you purge the atmospheric air out of the line used to feed new refrigerant into the system. Tip #2 In this situation at home, buy a big can (of proper type) refrigerant with a gauge on it, purge line and hook up to low side after proper vacuum drawing. Hook up your manifold gauge high gauge side to high pressure side on the car. Look up the recommended PSI for low and high according to ambient temp. Concern yourself mostly with the high side pressure, add refrigerant until your at the max pressure on high side and your done. Obviously making sure the low pressure is in ballpark and AC in vehicle is set to max (lowest temp) and highest fan setting. Its just easier to pull the trigger on a big reusable refrigerant can and keep and eye on getting to your desired high side value number on your high side.
Well the Bentley warning did tell him to sit still and keep the vehicle running. My guess is they want to make sure the head gasket blows adequately. Seriously what type of message is that.
@Deathignator that's ridiculous - engines heat up at idle. If your water pump isn't circulating coolant through the cylinder jackets the engine will get hot as hell and even a radiator fan is insufficient to cool the engine
Over the yearsI have replaced these valves on several 80s and 90s Fords. They are the easiest and cheapest parts to source and were a common failure. I'm also surprised that you didn't have to clear any current codes that would prevent the compressor from turning on. You are very fortunate. Good video, and nice job.
This happened on my mercedes. The compressor looks identical. Super easy fix. I learned to remove it faster with compressed air after evacuating the system. It was really jammed in there. Pulling a vacuum after you install it will also help get it seated.
I bought and sold many many cars; in a hot climate. Virtually all had no working A/C. So off to Pep Boys I went and bought those cans of refrigerant for about $5. With the simple connector hose to the low side ; it would draw in and the A/C blew cold !. This worked 100% of the time. One bottle ; $5 , FIXED !!!. Selling a clean car with working everything is a piece of cake 🍰 !!! Happy times .
I've replaced the rcv twice in my audi and bunch in friends vw's. Bought from the site mentioned. I don't know why they keep failing and would like a definitive answer. In any case I will keep replacing every couple years rather than replacing compressor. Leave a couple pounds in the system and it comes out easier.
Sam I owned a Bentley Arnage and I like you thought ok I need to replace the compressor so I had it done. Problem was once all done same problem. Turns out yes that valve was a solenoid and once that was replaced all was well no more issues. I wondered why I would hit a pot hole and the cold air started come out, light comes on in my head SOLENOID. Sure enough.
Sam, probably an overheat because now there's extra heat load into the cooling system from the A/C. I noticed when you were regassing, I couldn't hear electric fans running. Thought they'd be on whenever A/C is on.
I'm a retired HVAC guy. Did not know about the RCV or the new cans. I have repaired and charged a bunch of cars over the years as a favor to friends, but not in several years. Thanks for the heads up!
Insurance adjuster for Bentleys - AC broken? = total it. Suspension bad = total it. Probably the same with Maserati, BMW, Mercedes and Land Rover as well.
Thanks Samcrac! This video was instrumental to fixing the AC on my 19 Cayenne Turbo. RKX tech’s valve worked…! Much appreciated! I’ve watched all your videos, you crac me up!! 😂
Similar thing on the back of the Chevy ls compressor. I normally take a paper clip and jump the two terminals in the plug and if the compressor kicks on the sensor is bad
Just a little tip....when you first open the valve on the can be sure the gages are still closed and the vehicle side is still under vacuum what you should do is back the yellow charging hose at the gage off a little bit untill you get a little refrigerant and tighten the connection at the gages ...what this does is purges contaminated air that in in the hose that holds moisture. It's a small thing but it's beneficial
15:09 This where you blew air into your system because you didn’t bleed the yellow line. I bleed the blue & red lines as well, just close the low side valve, crack open the valve connector, flow refrigerant through until liquid comes out through the fitting, and repeat the process on the high side valve. This insures there is zero atmospheric air in the manifold.
I used to own my own shop before I retired and I hated those type of can taps, I always used a puncturing can tap and the one I still use has availability to use any size can, it's well worth having.
"The whole thing need to come off" Why are car designs for maintenance so bad? My brother had to change the blower in his Mazda 3 2007, the manufacturer procedure required to rip off the whole dash. We managed to do the job without ripping off the whole dash. We went from underneat to unplug the blower's connector and the rest was fairly easy to access. So in short the procedure want the whole dash ripped off just to unplug a single connector. It was pain unplugging it, if they had done a better plug design it would have been easy to unplug it.
Love these videos!! However, not sure if you did this but you must run a vacuum pump on thr AC system to remove any moisture. If not you will likely destroy compressor in due time.
The guys who claim it’s fake that your cars break after fixing them have never worked on their own car once in their life. This is exactly how it goes literally every single time 😂😂
Hey Sam, when recharging my AC gas, I use a clear hose from the can into the system where you can see the liquid moving into the system, I've been in that situation with a faulty valve or a can that didn't pierce properly and I'm there for hours checking the car only to find out that gas wasn't flowing
It is a variable pressure valve, thus it is not simply an on/ off as a traditional clutch operated compressor🎉 When you need colder air, the valve can fully open. When you need warmer air, it would partially close.
Ran into the exact same thing trying to put a can in my vehicle last summer, had to buy new hoses, damn EPA Really cool a company makes replacements for those valves AND a human answers the phone! Amazing nowadays! Good luck with the overheating, at least you didn't have to take the front end of the car apart twice.
I had the same issue refilling my Audi but was able to back off the needle valve and invert the can to fill. My 7 series Audi also tends to blow fusible links for the cooling fans. Annoyingly they are located under the strut tower brace which must be removed to access them. Common issue on those and no fun in stop and go traffic after you notice the second one has blown. Temporary fix to get home is use the start stop system so it doesnt over heat.
A very educational video Sam not that I will be in the same position any time soon I drive a Mercedes EQA250 electric car and I haven't found where the air conditioning unit is located yet but i will be checking out things under the bonnet soon. Your videos are so good to watch keep them coming mate.
As for the overheat. Check the water pump activation valve. Passenger cam cover to the front, it is a vacuum solenoid. If coolant is found in it, replace the solenoid and water pump. While you are in there replace the thermostat, the front end needs to come off. The 2.9, 3.0 and 4.0 are known for that.
@Samcrac the reason these valves fail is because the AC dryer has reached its capacity of absorbing moisture and the moisture left in system causes oxide inside the valve - resulting in the valve failing to move when needed to compensate pressure between high and low side and the system shuts the AC off. If you are lucky, many newer cars have the dryer as a cheap filler element inside a tube attached to the AC radiator. That element can be replaced separately by removing a plug from the bottom side of the tube and changing the element. If the dryer is not replaced the new valve will soon fail again.
This is a very helpful video for anyone who is even slightly mechanically inclined that wants to save some money on their AC. However there’s still a good chance the front end is still coming off.
In my experience, most of the time if there's an issue with car's air compressor, the issue is usually connected to the electrical component. I can usually just pick up a clutch/coil kit for it and slap it on for cheap. Tends to save a bunch of money
Fantastic! Smart as always, I’m down to do any project you want man don’t even need screen time, I just want to buy the cheapest 2018 S63 on autotempest and bring it back to fully running if needed
Just awesome........ collective knowledge for the win. Really shows when we combine all our knowledge how far we can get. Shame on VW however for not putting this forward as a repair option.
The channel gives us so much hope we can fix these expensive problems more cheaply. Right before a good kick in the nutz. Another problem develops and its back to being lawn art.
Darn fine video. I simply enjoy the way you tell your stories when fixing things. I'm always cheering that you'll solve the problem at the lowest cost possible even if it involves some weird method. I want you to beat the dealers who overcharge customers although I know that there must be honest dealers around. Maybe I should blame the automakers for making simple fixes so complicated. Eight hours to change an air compressor is ridiculous. I'm so glad I don't own a car. Solving one problem only to have another problem occur is not something I want to deal with. It's fine if it happens to you in order to have more content to show. Thank you, Sam. Keep the enjoyable and interesting content coming.
It's funny I had the same thing with the can valve last summer. Looked at the valve and noticed there is no more pin. Kinda like the new gas can with the horrid spout.
I have had numerous questionable control valves when it actually was the connector. New connectors are like $12. Always coat the pins with stabilant 22.
Just fixed this problem few weeks ago, it was the valve issue as well, in my case the low pressure was too high somewhere around 65 psi (it should be around 25-35)but I could confirm the a/c compressor was working. Order the new valve from China cost me 30 bucks, the cool air came out again. My car is Q5 2.0T 2014 gen3 ea888, the a/c compressor was manufactured by Denso, Japan company. Btw the way, another common failure could be the refrigerant pressure sensor which is located on the condenser.
That is true my vw was blowing hot air as well I went out got me a new AC compressor valve for $20 refill it and it’s been working ever since Ice cold and that was a long time ago
This is pretty much the curse of modern cars: minor components failing, usually cheap and easy to replace, but 'computer says' something major is wrong and a main dealer will charge nearly the value of the entire car. And they probably don't even know any better. Years ago, when cars had just started going all electronic, a friend of mine who was quite a genius at electrical repairs made a small fortune fixing nonsense like this.
Hey Sam. Just noticed some woodworking machinery Shaper and Table saw. As a woodworking nut how about some videos on your shop and machinery. Thanks, MW
Another thing is that if it's not real warm outside, you need to put the can in warm water to get the pressure up high enough to get the compressor to accept refrigerant. This was the case with my Mercedes. Exact same issue as your Bentley.
They can design for easier maintenance for sure, but they make more off of service if no F's are given to design. Most often different parts of the car are developed by different teams who don't care what the others are doing, which is why there are so many problems with access to some things. Back in the day teams worked together to make an entire car together which made things so much better.
Sam, I haven't had AC in my daily driver VW for 6 years because the shop quoted me $1k to replace my compressor. After watching this video I bought the Control valve from rkx and installed it. It took longer than id like to admit but I finally have cold ac in my car again. Thanks Sam!

I bought and sold many many cars; in a hot climate. Virtually all had no working A/C. So off to Pep Boys I went and bought those cans of refrigerant for about $5. With the simple connector hose to the low side ; it would draw in and the A/C blew cold !. This worked 100% of the time. One bottle ; $5 , FIXED !!!. Selling a clean car with working everything is a piece of cake 🍰 !!! Happy times .
I've replaced the rcv twice in my audi and bunch in friends vw's. Bought from the site mentioned. I don't know why they keep failing and would like a definitive answer. In any case I will keep replacing every couple years rather than replacing compressor. Leave a couple pounds in the system and it comes out easier.
Sam I owned a Bentley Arnage and I like you thought ok I need to replace the compressor so I had it done. Problem was once all done same problem. Turns out yes that valve was a solenoid and once that was replaced all was well no more issues. I wondered why I would hit a pot hole and the cold air started
come out, light comes on in my head SOLENOID. Sure enough.
Sam, probably an overheat because now there's extra heat load into the cooling system from the A/C. I noticed when you were regassing, I couldn't hear electric fans running. Thought they'd be on whenever A/C is on.
I'm a retired HVAC guy. Did not know about the RCV or the new cans. I have repaired and charged a bunch of cars over the years as a favor to friends, but not in several years. Thanks for the heads up!
Insurance adjuster for Bentleys - AC broken? = total it. Suspension bad = total it. Probably the same with Maserati, BMW, Mercedes and Land Rover as well.
Thanks Samcrac! This video was instrumental to fixing the AC on my 19 Cayenne Turbo. RKX tech’s valve worked…! Much appreciated! I’ve watched all your videos, you crac me up!! 😂
16:48 Lets forget that sticker, but ir got me haha
you beat me, saw that too lol
Similar thing on the back of the Chevy ls compressor. I normally take a paper clip and jump the two terminals in the plug and if the compressor kicks on the sensor is bad
Whoever is watching this video, I hope this day will be a great day.😇
Just a little tip....when you first open the valve on the can be sure the gages are still closed and the vehicle side is still under vacuum what you should do is back the yellow charging hose at the gage off a little bit untill you get a little refrigerant and tighten the connection at the gages ...what this does is purges contaminated air that in in the hose that holds moisture. It's a small thing but it's beneficial
dude made a 5 minute video into a 18 minute video. Meanwhile Mat Amastrong would probably built a car a by now.
15:09 This where you blew air into your system because you didn’t bleed the yellow line. I bleed the blue & red lines as well, just close the low side valve, crack open the valve connector, flow refrigerant through until liquid comes out through the fitting, and repeat the process on the high side valve. This insures there is zero atmospheric air in the manifold.
I used to own my own shop before I retired and I hated those type of can taps, I always used a puncturing can tap and the one I still use has availability to use any size can, it's well worth having.
Great save, sorry about the over heating if it's not one thing it's another.
thanks.
Replaced solenoid valve on our Audi when it stopped cooling - it did the trick and blows ice cold. Satisfying to fix, frustrating it needs to...
"The whole thing need to come off" Why are car designs for maintenance so bad?
My brother had to change the blower in his Mazda 3 2007, the manufacturer procedure required to rip off the whole dash.
We managed to do the job without ripping off the whole dash. We went from underneat to unplug the blower's connector and the rest was fairly easy to access. So in short the procedure want the whole dash ripped off just to unplug a single connector. It was pain unplugging it, if they had done a better plug design it would have been easy to unplug it.
...great programme ...so entertaining and useful
Love these videos!! However, not sure if you did this but you must run a vacuum pump on thr AC system to remove any moisture. If not you will likely destroy compressor in due time.
The guys who claim it’s fake that your cars break after fixing them have never worked on their own car once in their life. This is exactly how it goes literally every single time 😂😂
This why you're special Sam!
Like that Blackwood too!
Hey Sam, when recharging my AC gas, I use a clear hose from the can into the system where you can see the liquid moving into the system, I've been in that situation with a faulty valve or a can that didn't pierce properly and I'm there for hours checking the car only to find out that gas wasn't flowing
It is a variable pressure valve, thus it is not simply an on/ off as a traditional clutch operated compressor🎉
When you need colder air, the valve can fully open. When you need warmer air, it would partially close.
RKX valve fixed mine as well. Great company and support.
Ran into the exact same thing trying to put a can in my vehicle last summer, had to buy new hoses, damn EPA
Really cool a company makes replacements for those valves AND a human answers the phone! Amazing nowadays!
Good luck with the overheating, at least you didn't have to take the front end of the car apart twice.
I love seeing you rescue these cars!
I had the same issue refilling my Audi but was able to back off the needle valve and invert the can to fill. My 7 series Audi also tends to blow fusible links for the cooling fans. Annoyingly they are located under the strut tower brace which must be removed to access them. Common issue on those and no fun in stop and go traffic after you notice the second one has blown. Temporary fix to get home is use the start stop system so it doesnt over heat.
You crank the valve down to pierce the can the crank it back out and refrigerant will flow.
A very educational video Sam not that I will be in the same position any time soon I drive a Mercedes EQA250 electric car and I haven't found where the air conditioning unit is located yet but i will be checking out things under the bonnet soon. Your videos are so good to watch keep them coming mate.
One of the best channels on YT! Thanks for the good content.
As for the overheat. Check the water pump activation valve. Passenger cam cover to the front, it is a vacuum solenoid. If coolant is found in it, replace the solenoid and water pump. While you are in there replace the thermostat, the front end needs to come off. The 2.9, 3.0 and 4.0 are known for that.
Brilliant. Love the way you figure out the issues - shame about the coolant issue now
I ran into the same Freon can problem a couple of years ago. I didn't even know they had changed it. Now I have an adapter.
RKX is great, bought their hybrid diverter valve for my 1.8t. Just as good if not better than Forge for waaaay less money
@Samcrac the reason these valves fail is because the AC dryer has reached its capacity of absorbing moisture and the moisture left in system causes oxide inside the valve - resulting in the valve failing to move when needed to compensate pressure between high and low side and the system shuts the AC off. If you are lucky, many newer cars have the dryer as a cheap filler element inside a tube attached to the AC radiator. That element can be replaced separately by removing a plug from the bottom side of the tube and changing the element. If the dryer is not replaced the new valve will soon fail again.
Thanks for the info! I'll look closer as to where the dryer is here
I had the same issue with the A/C cans last summer, took days to figure out what as wrong
This is a very helpful video for anyone who is even slightly mechanically inclined that wants to save some money on their AC. However there’s still a good chance the front end is still coming off.
In my experience, most of the time if there's an issue with car's air compressor, the issue is usually connected to the electrical component. I can usually just pick up a clutch/coil kit for it and slap it on for cheap. Tends to save a bunch of money
Every inch counts… when you’re in a tight space… perform to completion. Lmfao @samcrac I’m dead. ☠️🤣🤣
Fantastic! Smart as always, I’m down to do any project you want man don’t even need screen time, I just want to buy the cheapest 2018 S63 on autotempest and bring it back to fully running if needed
I would have tried the balloon test with the new valve as well...
Just awesome........ collective knowledge for the win. Really shows when we combine all our knowledge how far we can get. Shame on VW however for not putting this forward as a repair option.
@14:03 It's really amazing what you'll notice... 🤣🤣 👍👍👍 Videography skill 10+
thanks Sam for the video probably i have same problem on my Q7 hence i tried to look over all system but without success!
As a 2006 Mini Cooper owner I’m laughing at the front end removal! Welcome to the club.
The channel gives us so much hope we can fix these expensive problems more cheaply. Right before a good kick in the nutz. Another problem develops and its back to being lawn art.
😂😂😂😂 effin Bentleys. Good catch on the A/C can and that was cool of Ryan too reach out. Hi to Corey 👋🏻 😁
That’s step-mom to you lol
@@charlie1832 indeed it is… 😂
Darn fine video. I simply enjoy the way you tell your stories when fixing things. I'm always cheering that you'll solve the problem at the lowest cost possible even if it involves some weird method. I want you to beat the dealers who overcharge customers although I know that there must be honest dealers around. Maybe I should blame the automakers for making simple fixes so complicated. Eight hours to change an air compressor is ridiculous. I'm so glad I don't own a car. Solving one problem only to have another problem occur is not something I want to deal with. It's fine if it happens to you in order to have more content to show. Thank you, Sam. Keep the enjoyable and interesting content coming.
The mechanic you talked to saying “but you still need to take the front end off!!” Is so crazy 😂 what an amazing video sam
Just dealing with the same issue with a camry.. The rusted retainer.. Sensor stuck.. Total bs situation..
Watch out for the cow patties out there when doing that job Sam!
It's funny I had the same thing with the can valve last summer. Looked at the valve and noticed there is no more pin. Kinda like the new gas can with the horrid spout.
NYLOG gasket-sealant and -lubricant is, what has to be used for installing of these hnbr-rings!!!
I have had numerous questionable control valves when it actually was the connector. New connectors are like $12. Always coat the pins with stabilant 22.
Just fixed this problem few weeks ago, it was the valve issue as well, in my case the low pressure was too high somewhere around 65 psi (it should be around 25-35)but I could confirm the a/c compressor was working. Order the new valve from China cost me 30 bucks, the cool air came out again. My car is Q5 2.0T 2014 gen3 ea888, the a/c compressor was manufactured by Denso, Japan company. Btw the way, another common failure could be the refrigerant pressure sensor which is located on the condenser.
Awesome tip from the AC guy and what a great result!
I posted the same info on the valve in the last video along with some other guys. Had similar issue on my 2006 Audi A3 Sportback
Crazy Sam I have an 08 touareg at is very intermediate.. leading to warm air.. hope this fixes my issue.. summer is close
That is true my vw was blowing hot air as well I went out got me a new AC compressor valve for $20 refill it and it’s been working ever since Ice cold and that was a long time ago
This is pretty much the curse of modern cars: minor components failing, usually cheap and easy to replace, but 'computer says' something major is wrong and a main dealer will charge nearly the value of the entire car. And they probably don't even know any better. Years ago, when cars had just started going all electronic, a friend of mine who was quite a genius at electrical repairs made a small fortune fixing nonsense like this.
Hey Sam. Just noticed some woodworking machinery Shaper and Table saw. As a woodworking nut how about some videos on your shop and machinery.
Thanks, MW
Another thing is that if it's not real warm outside, you need to put the can in warm water to get the pressure up high enough to get the compressor to accept refrigerant.
This was the case with my Mercedes. Exact same issue as your Bentley.
They can design for easier maintenance for sure, but they make more off of service if no F's are given to design. Most often different parts of the car are developed by different teams who don't care what the others are doing, which is why there are so many problems with access to some things. Back in the day teams worked together to make an entire car together which made things so much better.
