"brake failure" on the dash

[Bendy toy]

That's quite sad really...

With what we spend on farkles, fuel and running costs - how much more would the "stuff" we all buy today - how much more would it make the end products..

But then if the multiple is £0.40-£3 - makes a bike quite expensive....

Very true but how many front engine covers have BMW thrown away because they have never sorted out the corrosion problem? The total repair costs must be enormous but they carry on with the same old same old. Similar story with shock absorbers. If they sold the bike with officially serviceable shocks they could include them in the service schedule, make money on that work and save on warty costs of "sealed for life" shocks failing due to glooped up oil.

This happened to me. It was the rear wheel sensor. Looks like an easy and cheap job. A GS911 would help here. Mine was done under warranty.

A side isssue for me was the self cancelling indicators not cancelling. That sensor seems to supply info for quite a lot of things.

So now the speedo is intermittently working! Set off and it reads zero then after about 3 miles suddenly starts working. Presumably it is a sensor confusing other sensors over tha can bus?

Check the sensor wire for a dirty connection or chafing. It runs to a connector just behind the shock absorber top mounting.

Change the final drive oil and look for metal filings. The sensor itself will play up if it gets to clogged with filings.

speedo failure is rear sensor.

speedo failure is rear sensor.

Thanks to all. Booked in and will be sorted shortly.

The bearing was £3 for me to buy. If BMW were buying it in huge numbers i expect it would be far far cheaper.

So it turned out to be the rear sensor as predicted. Fault was due to rather a lot of water ingress into the final drive oil. Unfortunately the job card recorded the cause of the fault and water ingress is not covered under warrantyso £100 lost. Not sure how the water got in as I had not washed the bike or been in deep water for months.

Interesting other problem which occurred from the sensor were the mpg and average speed on the computer went mad reading 19 and 2 respectively. Anyway all sound again.

i was wondering if the breather on the final drive is water tight, cant see any other way for water to get in, i have seen a relocation kit for it, i had a few droplets of water at last oil change.

When I was changing the faulty rear sensor on mine at around 25k miles, I noticed that the oil in the final drive was a bit milky looking, too.
Got it changed asap!
There's obviously an issue with water ingress there.
Good old BMW holding up their hands to a problem again! Oh, what a minute, they didn't.
That's why I cancelled my BMW Extended Warranty. Only time I ever used it was for front wheel bearings for my K1600GT. By the time I paid the excess there was no benefit at all.
Now have European Roadside recovery for £57 for the year. Any use? Don't know, all will be revealed if I ever need it.

I change the FD oil at every engine oil change using the old swing the FD backwards method.

Simply dropping the oil with the drain bolt changes the oil (obviously) but does nothing to make sure the expensive paralever bearings are lubed. They move only a few degrees each way so the needles will rub themselves dry.

Why all the fuss? My bike needed new paralever bearings and bushes at 50K. The parts alone are silly money from BMW. If they had been regularly opened and moly greased they would still be running fine.
