All, I have a 2004 K1200GT in fine condition at 30K miles -- in today for service (fluids; brake/clutch flush) -- fault code for speed sensor or ABS was noted -- was reset and occurred again.  Brakes are working fine at present -- service manager says could be either speed sensor or dreaded ABS unit -- $400 for speed sensor/3K for ABS unit.

...OR...I could leave it be and hope all keeps working despite fault code...

Any advice from you all -- fluids/flushing has been done routinely...brake fluid was clean at this flush...

Thanks for any insights

Kevin/KJO

If the technician wasn't able to determine whether it was the sensor or the ABS pump he needs to check his work. The dealership's sophisticated system can tell what it is. I have seen them 'fail' right after a thorough flush because the screens or filters inside have debris lodged in them which moves and seizes the plungers.

Your '04 K1200GT should be equipped with the 'dreaded' servo ABS unit and currently there isn't an easy or simple way to get those rebuilt. There's a guy I know here near Seattle who has the tools and successfully rebuilds the mechanics of the servo units. There's also a a guy in Japan who can repair the electronics...the logistics of getting it done can be daunting. Also, it's a pain to remove the pump yourself and most dealerships will choose to avoid installing a rebuilt unit due to liability.

Do you have a friend who has a GS911 or the Moto Scan app from Germany (my preferred method) and appropriate Bluetooth module and adaptor cord? It would be good to be able to check, determine the fault reason and attempt to clear the code yourself.

Thanks TWB -- his sensor did say it was a speed sensor fault but that it could be related to the ABS unit and could not guaranty  that, after replacing the sensor, that the ABS unit would not indicate a fault....not sure how they tie together but, apparently, they wanted me to be aware....

My question was more along the lines of if all is working OK at present (as it is) should I spend the money to replace the sensor simply based on the fault code for the sensor ...?

I have been looking around on fleabay and other places for a scan tool for my recently acquired BMW X5 and I saw a lot of scanners that with an adapter would do the K1200.   Less than $100 Ozzie
