Glad you are back up - hope someone can help me with some advice. 2002 KRS, 20k miles, original battery, always starts immediately. About one week ago, ABS (Brake Failure) light came on (fast flashing) about 10 minutes into a ride. Rear servo is disabled, front brake and servo work fine. Stop, ignition off, resets the system, typically does not fail again until EITHER brake is applied. I am told that weak battery (or bad tail light) causes failure light immediately, not after several minutes. Trusted dealer hooked up to diagnostic computer, result is "Bad ABS Controller". Expensive news. Question - go ahead with expensive repair or swap batteries first. BMW cars are prone to bizarre behavior when the battery is weak. Should I impute this for the bike as well, or does the computer know best?
Suggestions are welcome.
