    ABS Light and Brake Light

    I have a 1999 VW Passat with 163,000 miles on it. As of like 2 years ago, the ABS and Brake light would come on and then shut off. Then after a few months of that it just stayed on all the time. Occasionally it will shut off and the ABS works fine for a few minutes then the lights come back on. I had my car scanned by 2 different shops about a year ago and nothing came up on the machine. In my original post from awhile back people said it probably my rear rotors being really rusty, so I replaced all 4 along with pads this weekend. All the rotors were still the original ones! So now we have all new rotors and pads on it and the lights are still on. I took my car over to my uncles shop and he now scanned it with this new genesis machine and all that came up was a code 00532. I think he said its something to do wit the airbags? After messing around with the genisis for awhile he came up with a message that said to check the #10 pin on the ABS module to check the current. Has anyone had these issues or have any advice? I live in Wisconsin and have driven 2 winters without the ABS so I don't really car, the light is just annoying the hell out of me. HELP PLEASE!!!

    It is common for the ABS module in these cars to fail. I new ABS module should cure your problems, but it won't be cheap. Look at spending $100-$150 for the module alone, or ~$300 if you get the pump/module. You will also need to take the time to match up the part numbers because they vary depending on years and models.

    I believe you have very common ABS module failure. You can't scan the code for ABS module failure unless you have a VAG-Com. Most people just take the module out and send it for refurbish. Here is a recent thread which may help you:

    Why is it that the abs works sometimes then?? How hard of a fix is it if I order a replacement?

    The ABS module failure usually consists of tiny connecting wires inside that become loose or corroded. They make intermittent contact, but it gets worse over time. Note that the prices cited aren't for a new unit; a new electronic module is more like $700. He's probably talking used, or a rebuilt. A MUCH better idea is to have your existing module rebuilt; you can drive without it, and there's no issue getting the right one. Removing and replacing it is an easy-to-moderate DIY. A rebuild of your existing module averages $200. Some places less, a few more.

    I found a guy on ebay that will rebuild it for $95. Here is the link. Let me know if it seems to be the right thing for me to do.

    Personally, I'd prefer to use a well-known service like ModuleMaster, rather than an eBay seller. But I must admit I haven't heard many horror stories about bad rebuilds from anyone.

    Generic scanners will not determine ABS faults on VW's, only engine issues. A Factory tool or the VAGCOM/VCDS will be able to better determine what is happening. If there is no communications, then the module is bad.
