Passat (B5) :: 2000 - AC Compressor Makes Squealing Noise
Jul 8, 2010
All was fine with it until a month or so ago. Now, after the car is first turned on and the AC is turned on, it makes a terrible squealing sound. The moment the AC is turned off it stops. If the AC is left on, it will generally make the noise for a good 20 seconds, stop, and then repeat that a couple more times(and the noise will cease for as long as the car is on).
I popped the hood and took a look (I'm assuming the compressor is on the lower left), and when the AC is off it spins fine. However, when the AC is turned on, the fan starts up, then it visibly stops spinning and really struggles to spin, causing the noise. Do I need a new compressor?

My 2003 Passat 4cyl turbo makes an extremely loud noise whenever I am in reverse...its seems to happen only when I tap the brakes. Several of my neighbors have heard the sound and expressed concern. I have had it at the dealer and they found no problem. I bought this car new in 2003 . The sounds seems to come and go. Maddening....It just happeneded again today. The car is garage kept, has only 31,000 miles on it, and has always been dealer maintained. The car is in pristine shape in and out.

So I have a 2003 Passat wagon. While driving down the road with no brake pressure applied the front right brake makes a squealing noise. As if the caliper doesn't release pressure....what should I do? Any hints?

Going to take a look at a 2000 v6 passat with 130k on it. They had the car serviced at Jiffy lube and now the engine makes a loud noise after running for a minute or so. The wrong oil was used. So I'm thinking the oil pump and screen are clogged up or the oil becomes to thin when warm therefore not providing proper lubrication.

It has been raining, finally, in bay area, thats the good part. The scary part is that, today I was driving normal close to 15mph and took a left turn at a traffic light and the car spun out. This was the second time in couple of months. Both times it had rained for long periods, road was not water logged.
First time had spun out of control on right turn and second time on left turn. Tires are close to 30K old. Wheels aligned 6k back, rotated 1k back. And passenger side CV makes clicking noise occasionally. Do not remember, the CV making the noise around the time of spin out on both occasions.

I have an 05 Jetta Wagon GLS 2.0 which has been amazingly resilient. I had the 100k check up done recently and everything still came up positive; the battery conked out at 120k; and I just recently replaced the stock head and tail lights out of proactiveness rather than them going out. But, I think I've run into an issue now. When I drive through a puddle (or otherwise get water significantly on the underside of the car) if I am running the AC at the same time the engine makes a squealing noise as though a belt is slipping due to the water. I presume is the case that a belt is slipping--and I imagine that is part of the reason it idles noisier than when it was new, but before my wife and I make a budget I'd see whether there are other options. As it is there are 130k miles on the car, it's a 5spd standard, and other than oil changes and the checks at 30, 60, and then 100k no real service has been done.

(2008 ES 350) I hear this squealing noise under the hood, I had the AC compressor rebuilt because I was told that was the cause, low and behold it's not, I only hear the noise when the car is in gear, but I don't hear it when in park or when I drive, but it's loud in drive and reverse. The water pump has been replaced too. Where is this coming from?

03 focus SE Wagon, Automatic Tran, has a bit of a problem. Whenever it gets driven through a puddle (big, small, paddling pool, etc.) it will make this high pitch squealing noise, and then when it gets shut off after driving through said puddle, will have trouble starting. (It will turn over, catch, run for .2 seconds & then the engine will cut out, but all the electronics will work) THEN! if you can get it started, it needs to be reeved constantly or it will stall when it idles. Lastly, if the conditions are ridiculously horrible, & you need to go some place, you have to '2 foot drive' the little beauty to whereever you're going. Now, she's been in to see the Ford mechanics and has 'stumped' them.

I have a 00 Passat 1.8T and the blower fan for A/C and heat has been intermittently squealing. I can sometimes get it to go away by changing the speed of the fan but I was wondering if there is any way to lubricate it up. Or should I just be looking for a new fan.

I have a 2003 Accent with 30,000 miles on it... It is making a variety of noises right now but the latest and loudest is that when I am backing out of parking spot or something like that it makes an awful squealing noise... What that might be?

I've got a 2000 Toyota Camry with about 120,000 miles on it. We bought it used in 2012 and it's been a great car except it makes a wha-wha-wha noise when driving. The sound speeds up as the car speeds up and becomes a whine at highway speed. The noise can be heard from both outside and inside the car and sounds like it is coming from the front of the car. About a year ago I took it to a mechanic and he said that he drove it as did another mechanic in the shop and they couldn't even hear the noise. The noise now seems to be getting louder. I think it is probably a wheel bearing and it is time to take it to a different mechanic.

Recently I've noticed more that when we first start the hyundai in the morning or after sitting a while and we use the brakes it grinds/ squeals a little and then doesn't after about 2 or 3 miles. Is this something to get checked out or should I spray something on my brakes to lubricate?
My next step that I though of was to get a simple automatic car wash cause it's been a bad winter in Rhode Island and the street shave been flooded with rock salt. I figure that might cause some friction under the pads.

Well I just put a junkyard motor in my cousins 06 passat. Fired it up today runs great and runs smooth. The only thing that concerns me is the top end makes some noise. Is this normal for this direct injected engine? Sound like its coming from the injector area and the injection pump......

Yesterday, i bumped into the curb as I got home, and today when I went to work the car is pulling very hard to the right, and makes a squeeling sound when I get up to speed. The ball joint looks bad, but can that cause this problem?

My Variant (2007, 48K miles) is experiencing a squealing noise during cold morning (below 45F) start ups? AC always off at start up and the noise goes away once the engine is warmed up. I brought it to the dealer last week and after leaving the car over night they told me the noise can't be duplicated which is a total BS. [URL].....................................

Have a 06 2.0T Passat that decided to start making some kind of god awful squeling noise today.. Sounds like it is come from the drivers side underneath possibly.. Funny thing is when you turn the car off it stays on for a few seconds till it runs out of pressure or something..
Car does have 103k on it if that matters..

I have an 02 Passat GLS. Its seems that when uts really cold out and I got to start my car in the morning it lets out a squealing noise. I just had my engine serviced so I doubt its any of the belts but I dont know for certain. Any VW buffs out there who know?

Since it's "auto repair season" in my driveway, I was working on my daughter's car (2001 Accent, 1.6 GSi) and noticed that the air conditioning compressor makes a noise (like a cross between a burble and a shriek) when it cuts out. I'm assuming it's the head unloader and was wondering if it's supposed to make a noise that's quite that loud or if maybe it's getting low on refrigerant - the compressor runs quietly when it's turning and the clutch doesn't make any strange noises.

Just picked up a 2001 GLX wagon and it is something my 93 did -- when opening the sunroof all the way, it makes a "popping" noise. With my last car, it was from something that snapped rendering it useless.
