Did you tell Module Masters that you think the servo pumps are operating?

The big hang-up in repairing the BMW I-ABS controller is the internal pressure sensors (they are/were not available) so IF your pumps are working then it doesn't sound like you have a pressure sensor issue.

It might be worth another call to Module Masters & having an in-depth talk with them as they might be able to repair your unit now.

Have an 04 R1100S ABS and am always concerned about this failure, so flush system every year. Have always found threads about removing ABS system that says the electronics can be separated from the pump to keep speedometer and brake light working, so possible to remove. Also, though I found this website, the company is in Germany, but maybe an option, but know nothing about the company, here is a link, https://rhelectronics.de/.

Don't hold your breath on this. For the 1150RT, they have been saying this since at least 2006 ish. I can't see them warranting the time to look into doing this for the limited number of bikes that will be left running. Most folk have ripped their Servo unit out and tossed it in the bin. It may well be different for the R1100S though.Me? Suspiciosly doubtful. However, as DR mentions, because it is the ABS element of the unit, they may be able to do something.

Hi, new to this forum. I've done two iABS removals (both on '04 R11s) due to failure and it is not hard. My first experience with iABS failure was while riding and that was NOT something I want to experience again. The electronic module can be detached from the pump (4 screws) leaving the wiring connection from the harness in place - this retains the speedo function. I used aluminum sheet from a hardware store to fashion a cover for the exposed part of the electronic module. Ditch the pump and associated hard lines and replace the old rubber lines with braided ones (I used Spiegler). For the front, I ran dual lines from the master to each caliper. The ABS light will remain on so I removed the light from the instrument cluster.

Hi to 041100S in Ark.
Lovely silver-looking bike you have.
Regarding the German firm RHelectronics, I know a couple of UK riders who were happy with their 800+ euro investment in having their iABS box repaired by that firm, instead of just ripping the entire system out.
Expensive, but if you so value the facility of the iABS, cheaper than a new module I suppose.


This is a list of the people I'd trust with my bike

After taking the bike to the dealer for a state inspection, failed. Tested iABS and told me servo unit needs replacement. I have copies of the test reports. I took the bike back, not paying them what they asked to repair. I then contacted Tom C at Rubber Chicken Racing for some assistance on this back in November. His work schedule was backed up to the point he was not taking any more new work. Put me in the "work to do file". I have not heard back from him yet. I will give him a call later this week in hope I can get him to take a look. Will be digging back into this shortly, as now my second bike has also failed iABS (2002 1150rt).

I quickly read through all of your posts on this and did not see anywhere where you said you checked the level of the fluid in the abs servo under the tank. That's what the low level error means. Before I would pay a dime I would check that . It doesn't cost anything for you to do it yourself. As far as I know the ABS servo will not give a low level error message for the master cylinders. It will probably give some other message for that. Pull the tank and check.

Thanks kioot, I have not done so, correct. I have taken the feedback from the dealership. I asked directly if the fluid was low, as I understood the readout to say, and the response was failure. I know, I know, probably not a good idea. As soon as I get a day above freezing, I will do it myself as suggested. Good point, thanks!

Additional details from Integrated Service Technical Application (BMW Tool) - readout from dealership

Identification Mode:

Fault description - measured wheel brake pressure at the front wheel is too high in relation to the control pressure.
Condition for fault ID - Voltage supply 9.0 V < U < 16.0 V Term 15 on
Fault Mem condition - Wheel brake cylinder pressure too high in relationship to control pressure
Action in service - Check break light with, hand, adjust break lights switch hand, check front pressure, check deviation values of internal sensors
check control unit
Note on effect - Brake servo assist front deactiveted, ABS control front deactivated
Fault description - break level too low
condition for fault memory - Brake level fluid detected too low for more than 8 secs
Action in service - check level in wheel circuits, check break fluid sensor and cables

Diagnostic Mode:
1st report -
Break Fluid Level - faulty
Break light switch - front and rear not operating
pressure - master rear = 22.38, master front 22.76 bar, wheel cyl rear = 21.79, wheel cal front = 66.07
control valve front and rear not active
Operating hours counter - front 3:15:00, fear 2:56:32
Battery voltage 12.05
Break light switch front = 2.75, rear = 2.75
Speed Sensor rear = 1.46, front = 1.56
Control valve front not active,rer not active
ABS control time front = 00:00:02, rear = 00:00:04
Operating Hours control unit = 64:50:42
Breaking time front = 3:15:00, rear = 2:56:32

I have readouts on my second bike(r1150rt 2002), but it looks like the test was unable to be done, will post separately.

Additional details from Integrated Service Technical Application (BMW Tool) - readout from dealership

Identification Mode:

Fault description - measured wheel brake pressure at the front wheel is too high in relation to the control pressure.--This could be pointing to a failed or failing internal pressure sensor (somewhat common I-ABS failure point).

Condition for fault ID - Voltage supply 9.0 V < U < 16.0 V Term 15 on

Fault Mem condition - Wheel brake cylinder pressure too high in relationship to control pressure-- Could be pointing to an internal pressure sensor issue as it would be difficult to get wheel side pressure too high without also having high control side pressure.

Action in service - Check break light with, hand, adjust break lights switch hand, check front pressure, check deviation values of internal sensors
check control unit

Note on effect - Brake servo assist front deactiveted, ABS control front deactivated
Fault description - break level too low
condition for fault memory - Brake level fluid detected too low for more than 8 secs
Action in service - check level in wheel circuits, check break fluid sensor and cables
--This usually points to either a low wheel circuit reservoir being low or a failing reservoir level sensor.

Diagnostic Mode:
1st report -
Break Fluid Level - faulty
Break light switch - front and rear not operating-- might be due to starting engine with foot on the brake pedal or holding in front brake lever during engine starting.
pressure - master rear = 22.38, master front 22.76 bar, wheel cyl rear = 21.79, wheel cal front = 66.07
control valve front and rear not active
Operating hours counter - front 3:15:00, fear 2:56:32
Battery voltage 12.05
Break light switch front = 2.75, rear = 2.75
Speed Sensor rear = 1.46, front = 1.56
Control valve front not active,rer not active
ABS control time front = 00:00:02, rear = 00:00:04
Operating Hours control unit = 64:50:42
Breaking time front = 3:15:00, rear = 2:56:32

I have readouts on my second bike(r1150rt 2002), but it looks like the test was unable to be done, will post separately.


On this problem I would check both under fuel tank ABS controller reservoir fluid levels & if OK then check the integrity & continuity of both reservoir level sensors (probably not the issue but could be so is the place to start)

It is sort of pointing to failed or failing internal pressure sensor or sensors but verify the above first.
