    Not only does he repair them, you will get a 5 year warranty. He redid my ABS-II this spring and it has worked flawlessly since. I paid them $250 for the job as opposed to $2500 to BMW.

    You may be in luck. Here's the deal. The intrigal ABS module is dead on my R1100S. I sent it to module master who fixed up some of the issues with it. But still dies when it's hot. I found a used one at beemer bone yard yesterday for a different model @ $700. That would require me having the ABS computer reprogrammed. Both BMW dealers here in the Seattle area can't do it. I guess BMW doesn't support that program any more for the dealers data base.

    SO.

    1) You can send it Module Master

    or

    2) Contact your dealer and find out if they can reprogram a used one

    or

    3) Get a used one, swap the computer on yours over to the used one (and here's where you may be in luck), Since my computer side is pretty much dead, but the pump side works. I may be willing to sell you the module and you can put your computer on it.

    PM me if you want to try that. If any one thinks this won't work, chime in. But I don't see why it wouldn't.

    Very simple :D - You have to change the whole wiring loom, both brake switches, wheel abs rings, certain sections of brake line and many other incidental parts. But you can still use the same brake calipers.

    And if your bike is a twin spark you're goosed. As they never made an ABS only twin spark bike and the wiring looms aren't interchangable between single and twin spark ignition (plus the switch gear and plenty of other switches use different end plugs). .

    When did you send it to Module Master? They were having issues until early this spring. Mine was a heat related failure issue that proved to be bad solder joints on the circuit board. Tyler found the solution, repaired the board, and all well. He said they were having problems with some units before that were a little elusive to diagnosis.

    I just got it back a couple weeks ago. Mine is heat related, no faults until the bike warms up. Then the speedometer sweeps and the ABS faults with a "rear speed sensor" message. I talked to him the other day about it and asked if he could put it in an oven and let it heat soak. He didn't seem to sure about it. The bike has been down since last fall as the ABS unit had 8 volts on the case which was shorting out the CDI and keeping the bike from running.. Took me a while to sort out what was going on, and honestly, I was tired of f-ing with it. I was not aware he had complete boards. That may have worked. Wonder how you replace the board and not reprogram it? I'll bet the program is proprietary and no way is BMW giving up that nugget.

    I was planning on sending the busted one back to him and letting him screw around with it as the more exposure to these units his shop gains, the better we will all be. Then just keep it as a spare or sell it.

    The sad part is it's priced at the point where it is cheaper to replace it than to buy a new bike. And it's going to be hard to sell a broken bike with a 3k repair bill attached. But, since the thing is down, you could always take this time to put a chip in it, pipe, lennies sprockets and modify the intake. Make a new bike. One door closes, another opens. That's what I did any way.

    I had to graft a new (used) hydro unit to my GS's brain to fix mine 2 years ago. At first I put the RS unit in straight in but it would not reset. Then I went to the dealer (I have a friend....) and we dinked with it for quite a while. There is an option in the BMW maintenance computer to re-calibrate the module so it works on different bikes, but apparently not all units will respond,,, possibly due to slightly different inputs between the RS and GS. the long/short is the hydro was replaced & works trouble free ever since.
