I was on a long awaited one day road trip yesterday. A good friend and I made our way across the state to meet other close friends for an early dinner, and then a visit to a very well regarded craft cidery (the sparkling alcoholic kind). A visit to the tasting room there was followed by a concert by a singer songwriter/musician that I really enjoy, and for free no less. It was about a four hour trip each way.

On the way there, for the first time ever, since I purchased my beloved 2009 R8 the car a year ago, I experienced a mechanical issue. And a very unpleasant it was, with the AC. Conditions outside the car were about 85 degrees and very humid, with brilliant sun. For the early part of the trip, I found I found that I had to turn up the AC a bit more than usual. Then a couple hours in, we started getting increasingly hot, and I turned it up to max. Even then, it was barely able to make the inside of the car livable. Not comfortable, but somewhat bearable. Both the level of cooling had dropped by a lot, and, even the fan speed (with it all the way up) was less than it should have been. We made it to dinner but were sweaty and worse for wear.

On the way home, beginning at 8:30pm, with the temperature now 79-80, and obviously, no mid day sun beating down on the car, the AC worked quite a bit better, Granted, that with it still near max, and certainly not at the level it should have been with that setting. I am nothing resembling an automotive cooling system expert, nor do I play one on tv, but I don't "think" this is the well known compressor failure. Granted, I could absolutely be wrong. But the fan also slowing down, and the fact that it worked at least well enough to get us home more comfortably, granted without the harsh sun and with lower temps, are hard to figure.

I know there is a great deal of expertise on this forum. Any thoughts or educated comments would be appreciated. I did speak to a friend who spent forty years in engine development, and knows everything about cars, and he said it could be a whole laundry list of things. That list included aging hoses having worn out and leaking, a core, or something similar in the dashboard, all the way to still possibly being the dreaded compressor failure.

Back in mid April, I got a Fidelity Platinum extended warranty coverage plan for peace of mind, so I know that any major failure will be covered. But if it is something like hoses, given that this car is mid engined, I suspect that might not be covered and could cost a fair bit, though I certainly hope not. Between the extended warranty, a new steering wheel, and scheduled work to replace the head unit next week, I've had to lay out what, for me, is a lot of money in a short period.

I had a similar issue a couple of months ago and it was a refrigerant leak. Turned out I had a small hole in one of the condensors. Any competent A/C specialist should be able to test the system using a dye to check for any leaks.

I bough my 2011 Spyder v10 June 27th and the ac went out a week later. 24,550 mile on it. Inspected by Audi at purchase and everything passed. Cost me $2,500.

Could be the ac sensor on the left wheel wheel/light side, but good luck.

Sorry to hear - sounds like a pretty terrible ride out there but a fun event, nonetheless. :)

Let us know what you find out!

I would guess with the age of the car it's just a little low on refrigerant. Not sure how hard it is to fill it back up in a r8 but it's not too crazy on other cars. Fill it back up and it will run fine for years even with a small leak. With what you said about the ac working when it was cooler out I don't think it's the compressor. Now if you keep running too low on coolant it might actually can damage the compressor by overworking it.

Refrigerant doesn’t just go low due to age or wear out. It’s either there or it isn’t. If it isn’t then there is a leak. After reading this long story I’m guessing you have a small leak somewhere.

Thanks to everyone. I have an appointment set up at the Audi Dealer for next week (soonest they had). I'll report back. I'm praying it is not something similar to what yellowpad expereinced. I know the warranty will not cover that. With my major recent outlays for the R8, that would seriously hurt my finances.

Cost of AC compressor removal and replacement below. Just had mine done today covered under Fidelity for a $250 deductible. phew!!!!
$2,400... $7,152... no great choices here. :) Let us know what you find out.

On a side note, though - the $7k+ seems a bit steep for the A/C compressor fix?

Yes, Fidelity is money well spent. Very glad I bought a six year warranty from them back in April. Just for things like this.

Well, I got a call from the dealership this afternoon. They say the problem is a "pressure switch"? They called it in to Fidelity to get approval for payment, said they will have an answer by Monday morning. I would certainly think this would be covered?

On another note, they also said that my power steering fluid needs to be changed, and that the fuel system should be cleaned given that the car is a 2009, and has only been driven 18k. These two things add up to about $400.00, so, in the interest of keeping this vehicle in optimum condition, as it is otherwise perfect, I approved the work. So, okay, I should be able to trust them. This has always been the most trustworthy and reliable Audi dealer in the entire area. However, they also said that my brake fluid needed to be changed. Interesting given that THEY replaced it a year ago when I brought the car in after purchasing it and driving it back form Florida. Now I am wondering about the other two things they "claim" need to be fixed?

Yep, glad to have the Fidelity. Nice little $250 deductible. Pretty labor intensive in the V8, given the engine removal. I have heard they have found ways to do the AC compressor w/o removal, but i know they did remove it. Spoke to one of the tech’s after. I am happy to have ice cold AC again tho AND to have only dropped $250. 6 years left on the warranty glad it happened only 5 weeks after buying the car too! Fresh new compressor!

the $7k+ seems a bit steep for the A/C compressor fix?
That's stealership prices! I got mine done, OTD, for $5K, including a service, since they have to remove the oil anyway.

I talked to a friend of mine today, a nearly forty year top automotive engineer. He said to tell them to scratch the power steering fluid change, as hes never seen that change required in even twenty year old vehicles.
