Here goes my story.. I have a 1999.5 Golf GL with the 2.0L 8v AEG engine. For a long time now the bearing inside the A/C compressor clutch has been squealing. Finally this month it became really bad, like it sounded as if it was going to seize up anytime, but the A/C worked 100%. I finally parked it into the garage and then pulled the compressor. I checked on ebay and they're many replacement bearings and clutchs for Vw A/C compressors...only not for my VW :( After checking the part label on the side of the compressor and then comparing it with a $60 working one I was about to buy. I soon realized that VW put two different compressors in their Mk4 golf/jetta cars. The used one is a different brand called Sanden (model: SD7V16) and I have one made by Zexel of Japan (VW Prt#: 1J0-820-803B). Most of the used part places near me have the Sanden and almost all of the replacement parts I find on ebay are also only for the Sanden :mad:. I typed the VW part# into various online part sites including Vw's and it gives me a Sanden reman compressor, not Zexel...? One thing I haven't been able to find out is if both compressors are compatible (parts, hose connectors, and electrical plugs?) Does anybody know? I have been able to find so much info on the Sanden SD7V16, and the opposite for the Zexel.

I have a feeling the reason for this is my MK4 was made in Wolfsburg, Germany and somehow made its way to Canada and any reman Zexel compressors I found online were in europe or the middle east, while the majority of Mk4's in N-A came from Brazil and seem to have the Sanden, hence why I can get one practically anywhere.

I would really like to keep my AirCon, but if I have to I'll just leave the compressor out of the car and get a different belt for the the Alter + Ps.

If all you need is a bearing, pull the pulley off, clean the bearing really well and look for some small numbers stamped on the edge of the exposed bearing race. A good auto parts store should be able to get just the bearing based on those numbers. I'm not talking about autozone, but find the warehouse that supplies the mechanics in your area. That's the place you need.

I've replaced a few of the bearings on the sanden compressors, but haven't seen your model. I agree, probably has to do with the fact that its built in Germany..I used the guy on eBay. Get the whole clutch kit for $115. Much better than the $600+ the dealer wanted. But that's only for the Sanden compressor, as you have already discovered.

I'm not sure about being able to swap a sanden compressor into the car, the hoses may be different, as well as the clutch connector. Did you talk to the parts guy at a VW dealer? They might have more info.

If you are able to get the bearing, be very careful pressing it in. If you distort the pulley, it will wobble when reinstalled and that will cause trouble with the pulley rubbing against the clutch.

I'm going to pull the bearing and have a look. I found a junkyard that surprisingly has one that will work with my golf and he's going to sell me it for $75. So might be worth it to just do a swap.

I tried to take apart the compressor, but apparently for the Zexel compressor you need to use some special VW puller tool to remove the pulley unlike the sanden. So that's it no go with changing parts. I've also looked at every used parts place with an hours drive of me and nobody has a working Zexel. I"m screwed.

Have you completely removed the compressor from the car? If so, take it down to the auto parts store and compare it to a sanden replacement if they have one.

You could also check part numbers on the AC lines. If the parts guy only shows one suction and one discharge line, with no note regarding what type of compressor is in the car, that's a good sign that the sanden compressor would probably bolt right up in place of the current one.
