- This is video is how to replace an AC compressor on a 2008 - 2012 Audi R8 with a 4.2l Engine. The manufacture wants you to completely remove the engine and tranmission in order to gain access to the components, this is not the case at all! It can be done with everything still in the vehicle. Special thanks to FCP Euro on their great parts and quick delivery! I cant say enough good things about them I have been using them for years with all of my Euro market vehicles.
Here is a list of the parts used from FCP Euro

Ok it came out!!!! Believe it or not, my 12 year old managed to do it. He rotated it and I use a pry bar to slightly nudge it for ward and it popped straight out. Nearly landed on his head but he was VERY happy with himself.
So it rotated slightly anti clockwise at and angle and then a little nudge forward and you’re home.
Thanks again for all the help.
Thanks so much for posting this. Great narration of each step and great camera work to actually see every detail. I came here from R8Talk forums and this video has given me the confidence to do my own compressor. Subscribed!
Love the video! Perfect step by step instruction on how to take it apart, and put the compressor back in. A few things to note. It would have been nice to show where the service ports on the engine are for the low and high side, what refrigerant it uses, and the label for how much refrigerant it takes. The only other thing that's a correction is the final piece isn't actually an accumulator. It's a filter drier. You were spot on that it has desiccant, and it captures all non-condenseables in the system from reaching the compressor. An accumulator is a gas chamber designed to protect the compressor from receiving liquid refrigerant back from the evaporator. Basically guarantees the compressor will always receive vapor and never liquid because liquid refrigerant will destroy the compressor.
I researched that the compressors on R8s are always failing, and its a toss up when they will fail. It makes sense why they fail considering they're literally right next to the exhaust manifold... Was the OEM compressor you pulled out a denso too?
Great stuff. This has been in the back of all Gen 1 R8 owners and is one of those known major failure points to a little great car. I will share it on R8talk... Great resource for R8 owners.. Cheers...
Great video - both the description and camera work! I’d heard talk that the AC compressor could be replaced without removing the engine. I guessed it would have involved loosening the engine mounts to partially reposition the engine. I’m surprised it’s even more straightforward than that. Audi obviously didn’t research this procedure as well as you did. Thanks for providing the details on how this can be done.
Great video, really clear walk through and well explained, one of the best I’ve seen. Many thanks.
Thank you so much glad it was helpful!
Excellent vid!
Thanks for this.
yes i already did it by using flybar thanks for the help 👏👌👍
after replacing new compressor done and starting the audi r8 there is light indicator coming out first the traction and suspension light and the gear light why ? but before was no lights on please answer many thanks.
Really great video, thank you. Is it just one required of each part listed above?
Excellent video, thank you for sharing step by step with us. I'm planning to take on this jobs byself at home since I have a lift. I also subscribe to your channel to support more video like this.
Also what is the part number for the last part
omg what an amazing video with instruction...dealers are gonna lose a lotta biz

Would you usually look at doing a carbon clean on the intake valves whilst the inlet manifold was removed.?
Great detail on replacing the compressor and the tools / access required to do so. Thanks for taking the time to create and post the video.
Yes I would perform that without hesitation if it was needed. This particular vehicle only had 10k on it and the valves were in great shape. It is good practice to clean valves on vehicles with direct injection when they are apart it just saves time and headaches in the future. Glad this video was helpful!
You are the man!! Ty. The first to properly document this procedure that I have come across. No chance you are located in and around NY?
I'm in Massachusetts
where is the location of expansion valve ?
I have a question what if u just leave the faulty ac compressor and not replace it!????🤔
Do you think that this job is doable if I am only able to lift the car about 24 inches off the ground? I do not have an industrial car lift.
It could be done but I’m sure it will be a little more of a struggle, it’s always easier with more access height.
I was negotiating with a dealership for a 2012 r8 until I saw numerous videos on this common problem . I am assuming heat destroys the compressor considering is the compressor is up against the engine and under the engine My question is would wrapping the compressor with fiber glass wrapping work in order to keep the heat off the compressor Thanks
I wouldn't think heat is to blame for the failure of these compressors. The feedback that I have had from owners is that failure typically happens when they are under acceleration and a loud bang / pop is heard. My best guess would be that the compressor has issues with vibrations due to the "drive shaft" that turns the unit, or it could be an overall level of pag oil used as well. When the compressors fail the internal shaft separates and explodes the case.
@@tsgarage523 would this suggest that the compressor unit is more likely to fail while the ac is on and similtaniously under high acceleration.
How do i know if the AC compressor is the issue or not?
You would have to attach pressure gauges and see what the system is doing when demanded on. Typically you can see the holes in the case of the compressor when they fail as well
Great video, thanks! Mine is still good, but I think I'd rather pay you for this job :) Looking under the plenum from the back of the car, I see a loose 2-wire connector facing to the back of the car sitting above the reinforcing bridge under the intake. Any idea what that is? (I had a rat nesting under the intake)
If the connector is under the air inlet tubes it is most likely the variable valve timing solenoids
Excellent video, well done. Approximately how long would the whole job take you?
If you have access to a lift it makes it easier but right around 10 hours to do it. It's better than the 40+ the dealer wants for sure.
@@tsgarage523 thanks very much. Kinda looked like a ‘long day’ job or a two day job with a couple of ‘while we’re on the ramp….’ extras 😂
@@Bigleefish that's for sure!
Is this really only applicable to 2008-2012 Gen 1 with 4.2 V8? What about the 2013-2015 cars?
The procedure should be the same
Hi there from the UK.
I am currently carrying out this job on my R8 (on axle stands laying on my back)😅
It is going very well with your guidance and I am just about to unbolt the compressor. My question is “can I remove the compressor with undoing the drive shaft”
From what I can see will she not rotate happily, pull slightly forward and then down through the hole with the shaft on?
Cheers for the great guide, I was about to put this into Audi and have my trousers pulled down. 😂
*without undoing the driveshaft.
It is hard to get it out with the shaft still on the compressor but if you unbolt the drive plate from the compressor you can slide the shaft out after
Go to min 17 it will show you the hub plate
Gotcha. Hopefully have time to tackle this stage tomorrow. Will let you know how it goes. 👍🏻👍🏻😎🍺
Hey man,
Ok! I am getting ass kicked. I have everything off (6 little ac driveshaft bolts removed) and the three AC bolts out but she just won’t rotate. Just so I am clear, am I trying to rotate the compressor clockwise? You hand movement right at about 16:40secs suggests clockwise but she just jams tight.
I am so close to having this thing on the bench it is killing me. .
The shaft and flange will stay in the car for now until you get the compressor out of engine bay. Once that’s out you can slide the shaft out and separate it in a vice
You might have to use a pry bar to get the pump to release from the dowels in the block
Hiya,
She is moving and free and basically floating in the hole. Should i rotate it clockwise?
Thanks for the superfast reply.
I’m texting from underneath the car right now. 😭🤣🤣
Yeah, you’re gonna have to rotate it. You might just have to use the prybar to bend the exhaust manifold, heat shield a little to give it enough from the squeeze out of it.
Glad you got it!
Glad it can help you! If you have any questions or need help please let me know. Thanks for watching!
Where are you located? I definitely need a carbon cleaning!
Sorry for the delayed response. We are located in Massachusetts.@@ShashankSingh-nr9gq
please answer asap are you sure that method will work on removing compressor without removing engine? thanks a lot if you answer 😁
left hand drive audi r8 v8
It should be inside the lines that connect to the evaporator core in the vehicle. Follow the lines into the dash and you should see the block where the valve is located
@@tsgarage523 ok thanks a
you can not answer my 2nd question because it can not pull out the compressor if you dont remove engine right?
It’s can be done easily with all of the pipes removed. You do not need to remove the engine at all
