AC Compressor problems....

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

Thx all, grin.gif

Yeah, that was the plan, I just thought I had a bit more time 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 smashfreakB.gif So I've NO CLUE WTF?!?! Flush.gif

And if the "A" compressor DOESN'T fit, then things'll get expensive frown.gif Which means no more mods for a while suicide.gif (btw, I just got the lower i/c pipe, and it looks sweet grin.gif, gonna try to get spacers next)

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

Dude, trust me, this DigiCam we've got at work..... dung.gif

Damn thing's an HP PhotoPC 3100Z 3.3 Mega Pixel Piece'o'crap smashfreakB.gif But it did the job, eh? 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 frown.gif But I figure next week sometime, as it's getting kinda iffy smashfreakB.gif

Thx, beerchug.gif

Thx Dude, Will do beerchug.gif

TBH, it kinda made me feel like dung.gif for having such a good day on Sat 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 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 crazy.gif

C'mon, change of subject smashfreakB.gif This one's depressing 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.

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.

Good Luck!

Drill mate, first off all my condolances to both of you... 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... 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! beerchug.gif

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

Mo, it's DEFINATELY under the hood 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 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 crazy.gif

Thx again, beerchug.gif

Yeah, it was the other half... grin.gif

She said it was "a terrible noise", so that was very helpful to determine the cause... 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...?

Well, we're gonna try and get it looked at by Audi this afternoon. Figure we'll go in and say, it's making noise, tell me what's wrong. And see what they have to say.

I also spoke with my Dad last night, and he mentioned that it might be low on fluid. And if I've a slow leak, it may not have shown up back in April when I had it recharged smashfreakB.gif

Any ideas/comments for this afternoon?

Thx, beerchug.gif

Did it make any noise before you recharged it? Or was that as a precaution?

Me thinks low gas wouldn't make such a racket as it did in that movie, but that's a guess really. IIRC that could produce a 'whining' noise, but not that loud. (A mates car had this once, but that was a big Chevy, and quite a while ago, so memory may fool me).

Having it looked at wouldn't hurt anyway, they should be able to tell you what it is when they see (hear) it... beerchug.gif

Hmm... so one could say the recharge had some effect at least. Cold usually effects gas, so I see what you're thinking... But in that case a recharge should cure it, at least temporarily (if there's a leak).

It could be, but I'm still thinking towards the compressor/'clutch'. Maybe more towards compressor, since recharging might have made it's job easier for a while...?

You found any place yet where they overhaul these aicons? They might offer even better expertise (in case the dealer is a bit iffy).
