Hi Passat Owners,
Sorry if this is long-winded for a BB, but here it is… I’m told the ABS Brake Module failure is a known problem for certain years, which happens to include mine, 1999. Nearly a year ago my ABS Brake Light went on and the dealership charged me $200 to tell me that it’d cost around $1,800 to replace my ABS Brake Module and pump.
A quick search of ebay turned up techs who remanufacture/recondition these modules for $179. With some directions and some hard work, I figured out how to remove it - I’m now a pro! - and sent it in. When it came back, I reinstalled it and all was good. Saved close to $1,600!!
Then recently, the light comes on again. I didn’t initially think to take the remanufacturer up on on their warranty. Instead, was a bad consumer and let a mechanic fleece me for a new alternator and battery which of course didn’t fix the problem. (Per the mechanic we needed to eliminate those as potential causes. Thanks, buddy!!)
Finally came to my senses and sent the module back in. They had it for nearly two weeks and when I got it back and reinstalled it, the ABS Brake Light remained.
Was told that I need to pull and clear codes. Since neither the Generic (OBD) scanner nor the AST Scanner were capable of communicating with the ABS Brake Module I took it to a mechanic with the VAG-COM scanner system. (It’s a 3rd party diagnostic software tool designed specifically for VW and other german made cars.) Anyhow, VAG-COM wouldn’t communicate with my ABS Brake Module either.
Conclusion: Either I’ve reinstalled the module incorrectly or, it’s simply dead and the remanufacturer/reconditioner sent me back a useless module and failed to honor their warranty. (I’m gonna get back to them about that.)
I guess I’m just sharing as I don’t think there’s much more I can do short of rechecking the connections and if that doesn’t work, replacing the module. I suppose I’d go to a junkyard and see if I can find one there as it doesn’t seem to make sense to put in $2,000 in a car not worth more than $6,000.
HOWEVER, if anyone out there does have any ideas or experience with this issue, I’m all ears!!
If anyone needs advice about how best to remove their module for reconditioning I can help with that.
P.S. An Emission Leak code did come up which a mechanic said would require quite a bit of work as the whole system needs to be checked for even the smallest cracks. Could take hours. Anyone have experience with that? THANKS!!
