Having same "ABS" issue. Already cleaned all (4) sensors, still having "Stability Control Fail" about every (3) start cycles, it will stay on for about (3) start cycles. Viewing this thread, I think I'll go ahead and check the solder joints. My question; Do I need to bleed the compete brake system after re-installing the lines on the module?
Thanks for the help.....

They are in business to make money. Cleaning the sensors might not fix the traction/ABS issue, but it's free to try it and it might save you $2800. The brake pads and rotors can be done much cheaper than that. Here's a complete set of drilled and slotted rotors plus ceramic pads on eBay for $480.

That's FOUR rotors and FOUR sets of pads for under $500.
Changing the pads and rotors is an easy do-it-yourself job. Even if you're never done it before you can probably do both sides in under three hours. Just make sure you have the right tools to start with. Running back and forth to the hardware store/parts store eats up time. If you need some instructions on how to change pads I can easily take some pics and show you how easy it is. I'm no expert, but I bet I can jack up the car, remove the wheel, remove the caliper, replace the pads, reinstall the caliper, and reinstall the wheel in 20 minutes.
Also, why are they telling you that the rotors need replaced? How many miles are on the car? They might just be trying to add to their bill.

I was told by the dealer that I needed new pads front and rear. I agree it looks about time (60k on vehicle, prob done once before but no dealer records. Have only had car since 49K). Rotors look alright. Only a mild outer edge lip. Not sure what tech spec thickness is considered minimum.
Any step-by step or photos would be GREAT!!!!!!!

I had the ABS/TRAC warning issue on my 2000 XK8. Cleaning the sensors didn't help, a new battery didn't, either. I changed the pads, still had the problem, though much less frequent.
The dealer said I had a code (can't recall the number, sorry) indicating the connection between the wheel sensor and the ABS module was bad. I replaced the short wire that leads from the wheel sensor up through the wheelwell to the top of the shock tower where it connects into the wireing harness. (Couldn't be easier, $45 for the part and less than an hour of my time).
99% of the problem solved, it threw the fault once since then.
GREAT job on the resoldering! That's my next move if it comes back.

Well My ABS solder project did not turn out like the above.. followed the steps .. all of the4 above.. put unit back in car .. terminals back on battery .. keyed it up and got .. incorrect part fitted. low brake fluid.. and a red brake light on the dash came on .. which is new since I did this. speedometer does not work now either.. before i did this just the abs light would come on the dash .. along with restricted performance. now .. codes: p1637,u1260,p1799..
just ordered new abs module ebay ..

So I did the ABS solder fix.. step by step .. solder joints looked bad.. so took out old and replaced with new.. looked good .. hopes where high.. re installed abs module.. put harness back in along with brake lines.. reconnected battery .. then got.. incorrect part installed ... low brake fluid.. red brake light on instrument cluster.. never was there before.. started it up .. restricted performance.. speedometer does not work now either.. orderd new abs module on ebay .. will see what happens when it gets here ..
just wanted to note.. the bolts that hold the abs module strip very easily .. also .. there are retainers on studs that hold the cover of the module to the main part of the module that have to be taken off also before the cover comes off .. not just the bolts mind you.
if you take the brake lines off for any period of time the brake lines have to be bled.
this was not a simple fix for me.. but had to be done.. I hope the new module corrects these issues.. still do not know why the speedometer does not work now.

Have you tried doing a google search on the codes you got?
Based on the fact that you have a U code it sounds like the ABS module may not be communicating properly with the other modules in the vehicle. A U code means a communication problem between devices. That might explain why you have no speedometer reading - the instrument cluster isn't getting the vehicle speed from somewhere.
If you didn't have these problems before you started working on the car, obviously something was either damaged, or not put together right. Id suggest checking over everything you worked on and making sure all of the electrical connectors are OK. Anything you unplugged for the work, unplug it again, and check all of the little pins in the connectors to see if one is bent out of place.
