    So--yesterday I take my 2007 Adventure (36k miles) into the dealer for a couple of recalls and alternator belt replacement. As I pull into the parking lot the "Brake Failure" light comes on. A couple of hours later the dealer calls and says the ABS module has failed---$2200 repair. In my research here it looks like Module Masters in Moscow, Idaho can rebuild these. This the non-servo Teeves version that first came out in 2007. Has anyone had this version rebuilt and can someone point me to instructions for removing the unit. Thank you.

    Don't be in too much of a hurry...unbolting and shipping off somewhere.

    Others will chime in with specific things to check before repair/purchase.

    Panic...not.

    Before you take it apart, do a thorough flush of your brakes, then disconnect each electrical connection, clean it and reconnect it. Make sure your sensors are gapped right, and all your switches are working correctly. Also, check all your battery connection, and make sure you battery is fully charged. Not as critical on the non-Servo ABS, but it still matters.

    IMHO it is very odd that it broke right after getting it worked on.

    It never fails. I wake up, think about buying a BMW, and then I read a thread like this by lunchtime.

    EVERY.

    SINGLE.

    TIME.

    Good luck brother, that really really sucks. :eek1

    Thanks Jim. It occurred when I first pulled into the dealer not after they worked on it. Can you point me to a description of how I get to/remove the module and the process for checking gaps on the sensors?

    Dom, for every one of these threads there are thousands of us out enjoying our bikes. Don't let the "problem" threads scare you. This is where we come for advice before paying the dealer. Often we find out it is something easy to fix and do the repairs.

    Hi dwf,
    I had the same issue on my 07 1200GS (not A) about 6 months ago. Down here in the land of OZ the repair was quoted at $3300. A little searching on the web (including this forum) revealed that the ABS units in 07 GS's is a known issue, and you may have a case to argue with BMW.
    I chatted to my dealer (procyles st peters for anyone local) about what I had found on the internet, and he was very helpful. He offered to speak to the importer to see if they would supply a new ABS unit at no cost.
    The request eventually went to Germany, with the response being that "if the bike has been serviced by a BMW approved technician in accordance with the service schedule, a new part will be provided at zero cost".
    Thankfully my bike met the criteria, and I got the repair completed for labour only (abt $300).

    I would have a chat to your friendly BMW dealer ASAP.

    Thank you. Since new I have done my own brake service. On the non-servo brake system the fluid flush is very easy and I have not seen the need to have the dealer do it.

    Can anyone describe the process for removing the ABS module? Given the fault reading I'm pretty convinced the failure is in the electronics of the unit. I spoke to Module Masters and they can repair it for $250.

    Haven't seen any documented instructions. Confirm using SEARCH.
    Is the process documented on the BMW DVD for your bike? I don't have one.
    If you have to remove it the old fashioned way...getting in there and yanking it out...you might want to consider documenting your process for others here at ADV who might/will be faced with the same task.

    That simply adds to the knowledge base here. Thanks in advance.

    Here's my pictorial, as an example, of "How to Remove an Alternator"

    PS...you can SEE the ABS unit in my pictorial...several steps in...but I have no idea what it takes to remove/reconnect it.

    Get off the computer and buy one. Just make sure you always have warranty coverage. Or you can take your BMW money and build a bomb shelter in your back yard and sit in it, your choice. My BMW coughed up a $2200 bill recently but the trip from ATL to Prudhoe Bay was worth it. She brought me home then took a dump.

    From experience, the servo brakes on the 1150 are fine until the ABS unit fails, in which case the system reverts to "residual braking" which is just a little worse than dragging a cinderblock on a rope to slow down. The non-servo ABS failure was largely transparent except for the obvious lack of ABS action.

    I suspect the system used in the non-servo 1200 bikes is similar to the non-servo 1150s in that you still have decent brakes but no ABS at all.

    My own opinion of the system has come around 180 degrees - I used to be a huge proponent of ABS brakes, until mine failed. I attempted a repair, and I *think* I got it right, but in the end I didn't trust the system to work. So I removed it and have come to the conclusion that proper braking technique trumps technology. I know some will disagree, but unless they're willing to buy me a new ABS unit, I'm going to stick with my unlinked/unservoed/unABSed brakes.

    I rode mine back from the dealer today and the brakes were fine minus ABS. It's a feature I paid for and want.

    What was the cost of the module? I assume $2,200 included labor. Although I thought I had kept up, I have not heard of frequent failures of the non-servo ABS modules. I like Jim's idea of cleaning out the system, adjusting to specs and giving it a go. Simple way to check if ABS is working...use it on dirt.

    $2,200 did include the labor. The fault codes indicate an electronic failure. I have talked to Module Masters and they immediately responded that they know what the issue is and they can fix it for $250.

    Then go for it. The lines should unscrew from the unit easily enough. They'll drip in the pan where the unit was, so I'd ziptie a finger off a nitrile glove onto each (not too close to the fitting, you want room for fluid collection) and be ready to bleed the system when the module gets back. The harness connector may take a moment to figure out, the connector on my 1150 and 1100 required a screwdriver to lift a latch, which simultaneously pulled the connector off the module. Bag and ziptie that, too.

    OK...although now a moot point, since Module Masters say they can 'repair' it [what exactly do they say the repair entails?],...But what is the cost of a new BMW ABS Module? Just buying the module and not including labor.

    Personally I would try the flush and fill, check connectors first and then send in the module for repair.

    Module Masters fixed ours and did a great job. The brushes on the motor get stuck in the holder and fail to make contact. They replace the brushes and holders with new parts.
    This failure will show up as two faults on the abs pump. There is a post here somewhere explaining the whole thing
