Hall sensors

Which years & models had these hall sensors problems?

The R1100s except the R1100S all had HES wiring harnesses that failed. The sensors were typically just fine. The very earliest R1150 bikes also had the bad insulation on the wires in the harness.

There have been occasional outlier failures of sensors but that is extremely rare.

So should I be making plans to replace the HES on my '01 R1150GS with 80K?

Probably!

GS Addict to the white courtesy phone. We need the photo comparing the two wiring harnesses.

What year was the first 1150s?
I know the last year was 2004.
I had a R1150R liked it except the ''wizzy brakes".

I believe the R1150GS came out in 2000, with the other R models still being R1100. I have a friend with a 2000 R1150GS, and I owned a 2000 R1100RT.

Then in 2001, the other models went to R1150.

Any manufacturer with any component (engine, tranny, cab, brakes) can be subject to hall effect failure. They are used everywhere from door to seat to camshaft to gear selection.

The real trick is finding if the are truly the problem.

Visual inspection of the wiring and connectors is a great start.

I looked at mine one winter while doing routine maintenance and then we had a big rain in August. $75.00 to get on a flat deck home. The wiring sheath came apart within those few months.

If in doubt, replace it and it's not unique to BMW or R1100 engines.

Just had a Cat D6T made in France in September have the sensor for the seat belt fail. Grabbed the harness and chunks of sheath came off. I suspect the cold boat ride across the pond made the seat bounce and the sheathing couldn't take the movement in the cold. Looking forward to seeing what happens to those machines in Rankin.

It's just more of the same ... wiring harnesses everywhere on Oilheads are failing because new 1990s Euro regulations required they be biodegradable. This "problem" is endemic with all European vehicles of the era. Complaints about cheap parts are irrelevant, the harnesses are performing as designed.

Oilheads were the first generation subject to the new regulations. Given time, engineers learned how to better deal with them. Subsequent boxers, for example, have CANBus electrical systems which reduces amount of wiring. Also many times cable ties are no longer used, ~3/8 inch wide rubber straps are used instead. Brake hoses are no longer rubber, but now metal wrapped teflon.

Keeping an Oilhead on the road is going to be a labor of love.

Naaaaw. These old bikes will go 4ever as long as you deal with the couple of issues they have.
