Don't take this lightly
The alternating lights indicate low fluid as El Jeffe pointed out.
I had this problem starting at 7000 miles.
At 25,000 miles I had to have the ABS unit replaced. List price for the part: $1700. Labor: 4.5 hours.
I was told over an over that nothing was wrong with the brake system. That was wrong.
I was told I had a low battery charge. That was wrong.
I asked where the fluid went, since my pads were not badly worn and it is a sealed system. I don't even want to go into the answer to that question, but it was along the line that the system must not have been properly bled initially.
The first time it happened, BMW Daytona didn't have a good answer and the lights were making me nuts, so I just replaced the rear pads even though they were only half worn. I figured that the reservoir sensor was just set wrong.
The second time, the dealer in Orlando added fluid and told me not to worry.
Finally, 10 days before CCR by the way, there was brake fluid on my garage floor. The ABS modulator was leaking.
I believe it was leaking slowly for a very long time. The problem is, if it is only leaking a drop at a time, the fluid burns up on top of the exhaust and you will never see it unless you take the left side body work off an carefully inspect. You might occassionally get a whif of burning oil, but if you are like me, you will assume it came from a passing car when you can't find any indication.
Eventually, the leak got bad enough that I found it.
BMW did offer assistance, to the tune of 50% of the part. They claimed they would have covered it completely if I had always done the 1 year brake fluid flush that the mechanics kept telling me wasn't necessary. They also said if I had brought it to them even 6 months earlier, they would have helped more. Well, I did, at a regular service, they added fluid and sent me on my way and it wasn't documented.
Do I feel abused? You betcha. But I wanted that bike ready for CCR and took the best deal I could get.
Make sure you don't take this issue lightly. Take off your left side battery cover and shine a bright light in there.
Better luck to you than I had.
