I have a BMW 1150 RT from 2004, the ABS problem is that both lights are flashing and I have resisual braking. I took the bike to the dealer and they recommend to relace the ABS unit that costs around 2000 Euros. What should I do first before expendind this huge amount? In fact the problem came only after a long period where the bike was stopped and after changing the battery. Regards, Miguel Silva

Alex ,
the battery is not your problem . it sound more like the starter motor giving you grief or alternator or regulator .
The electronic system on these are Bosch which are very sensitive to fluctuations of power .
Now when your starter draw power it really sucks power out of your battery and hopefully you have enough for the rest of the appliances .
the hard line of all this is that the battery may look good and hold the charge for a while but once the starter motor draw power to start the bike , you have very little power left to service the rest of power needed for the electronics . Make sure the alternator give you enough charge , test it while running , it should give you between 13.5 V to 14.8 V output or see if you accelerate the bike the headlight becomes brighter . If the light stays dole or dimms while giving a bit of gas , your alternator or regulator has a problem and will have to be tested and replaced .
have a look at all this and let me know how you go

I'm guessing the TPS is bad, located on the Throttle body. If that doesn't do it check fuel pressure, have had fuel pumps cause that problem esp if the bike has been in accident, cracks the fuel pump inlet tube causing it to lose pressure.

Because the fluid services both side evenly, you should only need to bleed the LHS. Just bleed it the same as you would a normal hydraulic system.

Put a small piece of plastic tubing over the bleeder valve, and make it as airtight as possible, I generally lock it with a piece of brass wire.
Place this into a jar with enough brake fluid to cover the bottom of the tube. Open the reservoir, it is easier with two people, open the bleeder valve, and pump like carzy, adding more fluid to the reservoir as required until no bubbles appear in the jar. Then lock off the bleeder valve and clean up the mess, after re-fitting the reservoir cover.

Easy job, but you need to take a few bits apart-
1. Remove the screen
2. Remove the silver plastic cover above the clocks (torx screws, should be in the tool kit)
3. With a little fiddling, you should now be able to get to the lamps at the back of the consul.
