OK, I've posted in the A/S3 forum before on this, but things have changed (and I don't think for the better /ubbthreads/images/graemlins/frown.gif)

For a bit now, my AC Compressor has been "Whining". It's done it with the compressor on AND off, so I figured it was the Clutch/pulley. I went ahead, and spotted an earlier model compressor from the 97-00 1.8T's (Mine's an 01) on ebay for only €81, so it's no big loss if it doesn't fit (HOPE it does though).

But we haven't had time to get the car in yet /ubbthreads/images/graemlins/smashfreakB.gif

Now this morning, I started up the car, and as usual when cold, she sounded a bit rough, only the compressor sounded a bit worse. HOWEVER, by the time I got to work (108.7 kms later) the compressor is ALMOST back to normal /ubbthreads/images/graemlins/confused.gif So, since it's no longer making the loud, bad noise, I figure it DIDN'T magically fix itself, and that, things may have gone from bad to worse /ubbthreads/images/graemlins/suicide.gif So I'm posting this to ask y'all's opinions, and see if MAYBE someone out there has some experience with this problem.

Now, Daniel, Jereon and Sven, y'all got to hear it first hand, so I'm DEFINATELY interested in your thoughts /ubbthreads/images/graemlins/crazy.gif

Thx all, /ubbthreads/images/graemlins/grin.gif

My opinion if it aint broke don't fix it! /ubbthreads/images/graemlins/grin.gif

Is the climate control working? Maybe it was the clutch that was stuck....but now it's free /ubbthreads/images/graemlins/confused.gif

If all is functioning A OK then leave it the HELL alone! /ubbthreads/images/graemlins/beerchug.gif

Well, the thing is, it now makes noise when the compressor is engaged /ubbthreads/images/graemlins/smashfreakB.gif

I'll take the NSC DigiCam out and make a quick MPEG so you'll know what I'm talking about, but it tripped me out this morning dude /ubbthreads/images/graemlins/smashfreakB.gif I pulled off the Autobahn, rolled down the window to show the guard my ID, and was like.... wait a minute, it's QUIET /ubbthreads/images/graemlins/UHOH7.GIF /ubbthreads/images/graemlins/EEK2.GIF

At least it doesn't sound like a Audi hoover now /ubbthreads/images/graemlins/yelrotflmao.gif

i would say try swapping it with the new compressor as you've already paid for it anyway and hopefully it will fit and solve all you headaches /ubbthreads/images/graemlins/beerchug.gif

Yeah, that was the plan, I just thought I had a bit more time /ubbthreads/images/graemlins/suicide.gif
PLUS, the fact that it originally got quieter when the compressor was engaged led me to think it was just the clutch/pulley. But NOW, it's louder when engaged /ubbthreads/images/graemlins/smashfreakB.gif So I've NO CLUE WTF?!?! /ubbthreads/images/graemlins/Flush.gif
And if the "A" compressor DOESN'T fit, then things'll get expensive /ubbthreads/images/graemlins/frown.gif Which means no more mods for a while /ubbthreads/images/graemlins/suicide.gif (btw, I just got the lower i/c pipe, and it looks sweet /ubbthreads/images/graemlins/grin.gif, gonna try to get spacers next)

Anyway, I'll try to get the MPEG up before/around lunchtime /ubbthreads/images/graemlins/crazy.gif

Movie's going up now, it's a .mov and like 5 mb /ubbthreads/images/graemlins/smashfreakB.gif But you'll see what I mean. The sounds a bit loud, and at first, it sounds worse on the .MOV than it does to the ear /ubbthreads/images/graemlins/suicide.gif

So anyway, you can check it out here.

And if THAT didn't work, then it's on pg 4 of the General Gallery.

Drill what's the idea that took me at least 1 minute to download /ubbthreads/images/graemlins/yelrotflmao.gif

It does sound pretty bad, and again sounds like the clutch, but it's hard to decipher really....

Dude, trust me, this DigiCam we've got at work..... /ubbthreads/images/graemlins/dung.gif

Damn thing's an HP PhotoPC 3100Z 3.3 Mega Pixel Piece'o'crap /ubbthreads/images/graemlins/smashfreakB.gif But it did the job, eh? /ubbthreads/images/graemlins/suicide.gif

I WAS gonna try and get the car in as soon as we got the other compressor, but Carmen's Oma passed on Saturday morning, so she hasn't been in the mood for much /ubbthreads/images/graemlins/frown.gif But I figure next week sometime, as it's getting kinda iffy /ubbthreads/images/graemlins/smashfreakB.gif

Thx, /ubbthreads/images/graemlins/beerchug.gif

Thx Dude, Will do /ubbthreads/images/graemlins/beerchug.gif

TBH, it kinda made me feel like /ubbthreads/images/graemlins/dung.gif for having such a good day on Sat /ubbthreads/images/graemlins/smashfreakB.gif And to top it all off, Carmen knew before we even made it to the Ring, but purposefully didn't tell me so I could enjoy the day /ubbthreads/images/graemlins/frown.gif Not sure how I feel about that, I would've left in a heartbeat if I'd've known she needed me, but it was a nice gesture I guess /ubbthreads/images/graemlins/crazy.gif

C'mon, change of subject /ubbthreads/images/graemlins/smashfreakB.gif This one's depressing /ubbthreads/images/graemlins/suicide.gif

If its anything like the noises mines been making since March, then its the compressor thats faulty. My garage replaced the pulley for free, and the noise went away for a while, but now the cold weather has returned, the compressor makes the same noise as before. When I first bought the car, the noise was like a high pitched whining, and after a few weeks, when I start the car in the cold morning, with the air con on, the noise sounded like an electric motor with dry bearings! Really loud. If I turned the air con off, then started driving, and turned it back on again after a few minutes of the engine bay warming up, the noise didn't reappear.

My garage says the compressor is at fault, and its not on the 3rd party warranty, and its £1200 to replace!

I live with the new starting procedure. Park the car, turn off the air con, turn off the ignition. Get in the car in the morning, start the engine, and after travelling a few miles turn the air con on. If I select Economy of course, I get heat from the blower on the windscreen, without using the air con.

I'll download your clip when I'm back at my desk, and listen to hear if the sound is the same as mine.
Mine's deafening when it goes off! Once warmed up, the noise goes for the rest of the day, but when cold, its likely to exhibit the fault.

Thanks Graham /ubbthreads/images/graemlins/beerchug.gif

What REALLY confuses me, is that it just got BETTER /ubbthreads/images/graemlins/smashfreakB.gif Which naturally makes me even more nervous /ubbthreads/images/graemlins/crazy.gif

Difficult to tell from the compression used with the sound clip, and on my SB16 card with cheapy speakers, but it does make a racket, and like mine, sounds like the compressor could be the culprit.

The thing is, it originally made the noise with the compressor disengaged, which would point to the pulley, right?

Drill I would like to help you but I am not a technical whizzkid (like Gammba).
It is strange tho that the sound went away and I did sound horrible there in Essen.
What I would do is try if your replacement thingy you bought fits and then bring the old one for refurbishing (and after that perhaps try to sell one of the two).
I can understand that you're worried tho, but I would replace and refurbish.

Drill...

When you say whining compressor...does it sound like its coming from around the dashboard compartment area as if it is.. I've had a similar thing happen on the A3 and fixed it myself or is it from the engine bay?

Drill mate, first off all my condolances to both of you... /ubbthreads/images/graemlins/frown.gif

As for the compressor, I didn't hear it cause that time the receptionist was hassling to get a connection with the credit card thingy and I was waiting in the lobby... So no idea what it was like, and I find it difficult to determine from the movie. Sounds like the clutch, but then again... /ubbthreads/images/graemlins/confused.gif

May be the best to see if you can fix it with the other compressor, at least then you know. Let's hope that cures it eh?

Good luck! /ubbthreads/images/graemlins/beerchug.gif

Thx Sven, Carmen's starting to adjust, but it while I only worked 3 days, it was still a LONG week /ubbthreads/images/graemlins/smashfreakB.gif And I would have sworn you were there /ubbthreads/images/graemlins/crazy.gif Must've been the other half /ubbthreads/images/graemlins/grin.gif

Mo, it's DEFINATELY under the hood /ubbthreads/images/graemlins/grin.gif I'm about 99% sure that it's the compressor, just not sure if it's the whole thing,or just the clutch. What I've been thinking, and y'all's comments just reinforce this, is that I'll prolly have the "A" fitted (if it works /ubbthreads/images/graemlins/suicide.gif) and run it for a few weeks/months and in the meantime, have my original one refurbished. I figure all in all, the "A" compressor, the cost of refurbishing (if possible) the std compressor, and labor should STILL be less than buying and installing a completely new compressor /ubbthreads/images/graemlins/crazy.gif

Thx again, /ubbthreads/images/graemlins/beerchug.gif

Yeah, it was the other half... /ubbthreads/images/graemlins/grin.gif

She said it was "a terrible noise", so that was very helpful to determine the cause... /ubbthreads/images/graemlins/grin.gif

Think y'r right, try to find a decent place that specialises in refurbishing these things (as they'll proly offer the best price). Unless the other one is running perfectly, in which case you might not even have to bother...?

Let me know how you get on, as I'd like to have mine replaced/refurbished too. Doesn't look an easy job on the A6 2.8 though (is there such a thing?)
