Re: Need some advice on my 2003 1200 LT
Depending on what is wrong with your modulator, there may be a solution to make a repair. Long story short, about 10 years ago my 2003 K1200LT developed a very slight leak in the ABS Modulator. It was one of the very first of these incidents that I and my dealer had even heard of. The bike was in the dealer’s shop for 11 months straight while I made hundreds of phone calls searching for a fix. I learned at that time, that ABS Modulator failures were caused by either a mechanical issue such as I had, or an electronic issue in its circuit board. We checked into a few claims that repairs were possible, but soon learned that was true ONLY if the problem was in the circuit board. To this day, I have still not ever heard of a repair being possible if there was a mechanical failure. I was in close contact with BMW Corporate all along, finally opting for a $2700 replacement. BMW did provide some help, which was much appreciated. When I finally had the bike back, I took it to a different dealer, for a thorough check-out. My LT got a clean bill of health.
Now to my point: I still have the failed pump - the one that developed the leak. Presumably, the circuit board is okay, but no guarantee. For the cost of boxing and shipping this HEAVY hunk of aluminum, it can be yours. Frankly, I’m not sure it is worth the effort to swap circuit boards. It may make the most sense to just disable the ABS as others have done. Good luck.
