No one likes sitting in a hot stuffy car, so this week i put my attention to fixing the aircon in my daily driver! Wasn't expecting this to be the cause....! Have Fun, Super Ron!
This video was very educational. My golf has fully charged a/c but its doesnt blow cold air I checked the pump today and hey presto just like yours it had come apart in the middle
You could have bought the ac clutch only it's available and a cheaper repair and much less work to do (bolts out bad clutch out nee clutch in bolts in) still great seeing how you diagnosed the problem all by yourself
I gassed mine a year ago (06 golf) guy said "hurr durr, it's not cooling like a new car because VAGs have problematic pressure sensors, need to rebuild the whole compressor" now it's been a year and it stopped cooling, VCDS shows no errors, shows me compressor turns on and off in measurements.
@SuperRon Thanks for all you do. I have a '08 Jetta 2.5 with a sanden compressor that cools very poorly, about 20 - 23C. I've scanned HVAC measuring blocks with VCDS and these are the most prominent values, Compressor Shut Off Code - 0.0, Compressor Load (5.7Nm - 6.7Nm), Refrigirant Pressure with AC on - (11.2bar - 12.2bar). Compressor is the type with a solenoid valve. What could be wrong?
These values are with the AC on and average outdoor temperature of about 35C. I need to know if its a weak compressor or a faulty solenoid valve before spending more money 😭
@@SuperRon My car detailer did not bother with the laborious and tedious ‘multi stage’ sanding and buffing process. Just one buffer pad with a polish compound, a liquid sealant application, final buff, then it was all done. The process took less than 15 minutes. I paid $50 for both headlights.
Thanks for the message 😁 yes all fine just mega busy with home renovations, I've got lots of videos filmed, just need to edit them up then they will be out to you guys 😁
I have an aftermarket compressor on the car when I bought but I didn notice after watching video that my center bolt doesn't spin with the pulley so I'm thinking I got the same issue because randomly my AC quit one night, no faults, got voltage at sensors and N280 valve so this could be my issue
Hi. I would like to ask you an explanation, looking at the broken bolts, were they screwed in clocwise direction or in couter clockwise. Thanks a lot for video!!
Hey Ron, Do you have a part number for that compressor? I have the exactly the same golf with the same compressor but cannot find the aftermarket model which looks identical as mine. Even a used one. Thanks!
No not sure why it happened, a few more people have said they have had the same problem on their mk5. A year later I've not changed anything else and still got ice cold aircon.
@@SuperRon Thanks. I'll try replacing this center hub (I found it on ebay), but I'm afraid it is likely that the compressor is internally broken having to replace it and clean the circuit. I hope I'll be as lucky as you :)
Finding it hard to find a pump, most are different. Mine is exactly the same as the Golf here, even same colour and year. If i find a pulley would you fit it using same method, im in Norfolk. Would it taking inner to outer pully work? Cant imagine much give in the rubber when new? Cheers
I had a hard time finding a replacement too, all others seem to be the clutch type. Yes that would work welding the inner to the outer, probably have to make a little plate to go in between, not sure of long term effects on the pump not being cushioned, but it would work 👍
Hi Ron (A3 1.6tdi 2014) My prob is that the clutch will not disengage . The clutch stays engaged even with power off.Would a new clutch cure this? Any info would be nice. Thanks
I’m looking at buying a 2010 golf and the seller tells me the A/C needs to be regassed. I wonder if there is more to it, and this could be the same fault. Looking at the location, if using an inspection mirror, I should be able to see if the centre part is rotating. If it isn’t then has the same fault as yours. If it is rotating then, pressure sensor, faulty compressor or some other leak. I don’t have access to the fault finding gadget you showed before I buy though. What would you ask them to reduce the price by? They are asking £3500, and the private guide price is £3100
You should just be able to see with a little mirror and torch, as you see from the video the 2nd hand part was cheap but the job can escalate with the centre bolt snapping on both pumps I don't think it's possible to get it out whole. But as you also saw I made-do with a little weld. A new compressor would probably be £400-500 plus labour, plus regas, could get very expensive. Or it could most commonly just be out of gas
If the AC is not functioning, assume the worst that the compressor has failed which requires a replacement. In Australia, this is a major $1,200 expense which easily writes off any older car. 🚙 ❄️
Hi great video thanks. I have a mk5 tdi. I have to run and accelerate otherwise it won't make cold. If I turn it on when I start the car it doesn't make cold air. Only after riding a bit. If I turn the engine off it stops again, so I can't turn the car off when I stop somewhere if I want to keep with cold on. Any suggestions? Thank you very much
I've not heard a problem related to speed before, hard to diagnose without investigating, but its nothing I've come across before. Thanks for watching 😁
This is a great DIY, although you butchered the old pump to see how it all connects, in essence all that is required is to remove the 3 screws and centre bolt to remove the outer section and then replace that on the existing one?
i have also a very weird problem, it cools but it cools very weak, and when i turn it off, it smells like wet dog and socks, have you ever got the problem. also A/C clutch repair is very rare these days here in Holland, most mechanics do the whole compressor.
Cooling weak is often a symptom of gas being low. Bad smell can be from bacteria build up on the matrix, you can get spray to squirt down your vents to cure this. Also check pollen filter is not wet
@@SuperRon but the thing is, about weak cooling quality, is that eveen after refill R134A Gas same, and my condensor is very dirty could that be the issue? or is the compressor slowly dying? im soo confused.
Hi there my air conditioning stopped working a few years ago 2008 golf gti , is the pulley system the same on that year as yours? Also i had a new compressor fitted but it still doesn't work!!? Do the pulleys come new with a newly bought compressor or just the main unit ?
I'm not sure which models have which, I've seen a 1.4 petrol with the other clutch type for sure! A new unit does usually come with a new pulley attached
@@SuperRon Ok thank you for your swift reply. Any suggestions would be welcomed, I realise it's probably Very difficult not having the luxury of looking at the vehicle but I'm £550 in and it's still not working 🙈
Yes hard to diagnose without investigating. Main things are, does it hold gas? Are you getting a signal to the pump with you turn the aircon on? Have you got any fault codes logged as it's a gti I guess you have full hvac
@@SuperRon Not entirely sure unfortunately I'm not at all clued up where cars are concerned. Prior to the AC failing it held gas for sure . I don't have a VAG com myself. Halfords said it was the compressor hence why I had it replaced but as I say that didn't resolve it . I'm told Halfords/quick fit etc is a fairly basic generic coding system. And it's climate control on the GTi so I'm told . Local VW dealer is saying £80 to diagnose and £161 hourly to work on it but I'm going to have to take the plunge to identify the issue at the very least, then take it from there. Thank you for your advice it's very much appreciated. Cracking video by the way , I wish I was more up on this stuff
Hi I have a 06 Volkswagen Jetta 2.5 l I was wondering if you know at what temperature does the cooling fans come on the electric cooling fan please help thanks
I have a 2.5 w a sanden compressor. Theres a switch on the ac that opens and closes and is usually the issue w these ac systems. Get a ngk switch for replacement. Ive fixed mine twice now from orielly parts and about to do it a 3rd times due to failing part
This video was very educational. My golf has fully charged a/c but its doesnt blow cold air I checked the pump today and hey presto just like yours it had come apart in the middle

My air con stopped working the other week and ATS couldn’t find the fault, I might give this a try and see if it fixes mine 👍🏼
It would be worth a check, thanks for watching 😁
@@SuperRonPolish and restore the damned yellowed and oxidised headlights! 🚙 🧼
@user-kc1tf7zm3b they are now done 😁

My ac has never worked on me mk5 gti got it re gassed no leaks couldn’t find nothing wrong with it so I’m going to try this 👍
Certainly worth a look 👍
All ok Ron? Have missed your videos the past few weeks. Pete

Quite possibly, after making this video alot of people have found the had the same problem
Hi. I would like to ask you an explanation, looking at the broken bolts, were they screwed in clocwise direction or in couter clockwise. Thanks a lot for video!!
No they are conventional thread, I checked when cutting the scrap one open, they are just fitted covered in lock tight. Thanks for watching 😁
Hey Ron,
Do you have a part number for that compressor? I have the exactly the same golf with the same compressor but cannot find the aftermarket model which looks identical as mine. Even a used one.
Thanks!
I did find it when I fitted it but that was a few years ago so no idea now unless it's in the video somewhere. Sorry, thanks for watching 😁
Hi, mine golf 5 plus. Air comppressor is working gas level is full but its not being cold. Little warm air its coming. How can we fix ?
Code read it and check fault codes
Do you have any clue what made the clutch to fuse? Mine has the same problem, but I'm thinking that the compressor might be damaged in the inside.
I forgot to tell that mine has the rubber ok, but the steel connection between the center hub and the rest of the clutch is what is broken.
No not sure why it happened, a few more people have said they have had the same problem on their mk5. A year later I've not changed anything else and still got ice cold aircon.
@@SuperRon Thanks. I'll try replacing this center hub (I found it on ebay), but I'm afraid it is likely that the compressor is internally broken having to replace it and clean the circuit. I hope I'll be as lucky as you :)
I always thought the pulley had a clutch in it too…..so what does engages the pump ?
Most are, but this has a electronic valve inside the pump that controls the flow of refrigerant around the system.
@@SuperRon thanks very much

Tacking together with small weld across inner and outer pulley I ment

Hi Ron (A3 1.6tdi 2014) My prob is that the clutch will not disengage . The clutch stays engaged even with power off.Would a new clutch cure this? Any info would be nice. Thanks
It sounds like you have the newer type clutched wheel, if it is sieezed on a replacement would solve it, if you can get them separately
@@SuperRon Thanks for reply I will try and remove it next few day .

Looks like you could do with another belt tensioner too! 😅
I solved that problem later, it was the alternator clutch pulley coming apart 😬
