How do i reset the abs on my r1100rt. my battery keeps going flat (i am getting a newone), could it damage the abs? Can i reset the abs while riding? Thanks

Look in your owners manual there should be a code when you bought the car if you still have it.

There are a number of comprehensive solutions for the BMW R1100 on youtube. Just search for "BMW Service".

Hey Gerard,
This sounds a little serious,,, I would not risk anything going wrong with such a nice bike,,, take it to qualified professional, let them listen to it.. and go from there..
good luck,,

Go and ride the bike Normally the ABS light should go off ...

I will need more info, but to start with did you reset the motronic after installing the new battery? Its pretty simple: turn on the ignition, open the throttle from closed to fully open 3 times. Then start the engine.

This is common on all bikes of this era. A new battery will resolve this problem for a while until it starts to drain down after 6 months to a year or so. The problem is the ABS system needs a good solid 12.5V or better to work at start up. This is the same time the starter also needs good power which puts a heavy load on the battery. They both end up competing with one another and the ABS computer creates a fault but the bike still starts. By starting it again and again helps because the battery is quickly charging each time you start. So, a new battery can help or put your bike on a trickle charge from time to time. The problem will never be fully resolved. You need to eliminate the fault before riding or your ABS system is non functional.

The abs light flashes when the battery is not good, to replace the battery on your bike you must remove the seat, then the two black panals both sides of the bike, then remove the two side fairing panals then the belly pan, undo the bolt that holds the tank down, lift up the tank and there id the battery just remove and replace, hope tis can help
