S80 T6 ABS Module Issues - Help?

I own a 2000 S80 T6 - no sympathy please - I should have read some of these threads before buying this beast - but it's mine now and I'm trying to enjoy it until I can sell it....

I'll spare you all of the details, but after two blown turbos, new brakes, struts, and tie rod ends - I am now struggling with an "abs module" problem.

My story starts out like many of yours - intermittent Brake Failure - Stop Safely ASAP warnings, along with check engine and brake light flashes....once they started staying on all the time, I started researching what can be done about it and what the culprit might be. In all my research, most of the thoughts pointed towards a bad ABS module and that there are several reputable folks who can repair them. Turns out, after being rejected by 3 rebuilders - I have the DSTC module (2% of these ???) and it can't be rebuilt??? As a result, I purchased a refurbished module and installed it. Same problem persists - dash board lit up like Christmas.

I did have new tires and brakes installed and this problem may have started shortly after this. I've been dealing with issues for over 2 years and the darn car spends most of it's time in the garage...can't recall the order of events.

I think I had a bunch of front end work done -tie rod ends, sway bar linkage, struts, new tires on all 4, rear brakes, etc. This was all done in August/Sept 2008. My first inquiry regarding a bad ABS module was in November 2008. Any thing sound suspect here?

I have heard some say it could be wheel speed sensors - not exactly sure how to check them - can I hook up an ohm meter to them to check for continuity?

Anyone need the refurbished ABS module I purchased?

Anyone have any direction for me at this point? Ideas?

Next stop - the driver's door lock actuator is now bad....

Thanks to anyone who can provide some self help direction on this thing.

Regards!

Craig

The last time someone posted with continuing ABS messages after replacing the ABS with a rebuilt, I suggested checking the plug into the ABS module. That turned out to be the problem. Were I you, I would check for bent/corroded pins and a clean,tight electrical connection. I doubt the front end work is to blame, but you never know -- the cable connector might have gotten jostled during the process. Good luck! Steve K.

Thanks for the tip - the plug was very clean, and for good measure, I blew it out with canned air. Went back on snugly - in fact, it was almost vacuum sealed when I took it off - nice tight fit.....
