Looking for a way out
Turning my BMW multi-functional wheel thing no longer has any effect.
I can still move between GPS pages by pushing left and right, but the zoom is dead. It also no longer controls the HEX ezCan, so it looks like a switch failure rather than the GPS unit/connection.

Is anything user take-apart-able or serviceable? I can live without it, but if there is something I can open and have a look, I'd like to restore it to operation. I don't know what a new switch cluster is, but I'm pretty sure rather more than I'm prepared to pay.

Cheers
Jimbo.

It’s connected to the GPS Jimbo and is designed to self-destruct once it’s been on the wrong side of the Severn Bridge for too long...

Alas with my sense of direction and without a GPS I don't even know what side of the border I am on....
 
Thought of trying motobins or moto works ??
They break bikes regularly might be less hassle than trying to fix it

I'm not sure if this information is still relevant, but here is a picture of the printed board prior to LINbus. (Pre 2013)

The board is supplied with a regulated 5V from ZFE. The rolling action is sensed by means of two hall-effect sensors, and there are magnetos in the wheel. There is no physical contact between the wheel and the switches, it's all done by magnetism, and the signal that is returned to ZFE is a square pulse from each of the hall sensors. Since the sensors are offset to each other, one pulse is preceding the other one, and there by is it possible to detect direction of rotation.
The clicking action is sensed by the black rubber at the center of the PCB. There is one switch on each side of the PCB, hense front and rear click. Also, the clicking action center position is held by a magnet centering the wheel, i.e there is NO spring that will pop out.

If the rotational signal is no longer working, the problem is either a faulty hall-sensor or magnet issue in the wheel.

If I should make an educated guess, I would start to search for a broken cable. Also, one of the hall sensors may have failed, They must both work in order to sense rotation either way.

This is pre 2013 print. I have no idea if the after-2013 wheels works the same. But even if the newer ones is LINbus, it must still contain hallsensors and magnets, and it must still make square pulses. However, the signals created might be converted into serial data prior to leaving the switchgear.

The signal from the board in the picture are as follows: +5V and gnd: 2 cables. Either of the clicks: 2 cables and the last two are the signals from the two hall sensors. The 4 signalcables a

The wheel unit used to be purchased as a separate unit, and is not all that expensive. It used to also contain it's own wiring. But LINbus might have changed all that...

Well there's an offer!

Thanks for the Help. I'll try and get it off this weekend and see if there is anything easy for me to sort. I think knutk's excellent post may be partly beyond my abilities. If I fail Andy can make me happy.

Have you given the GPS unit connection and the GPS holder connectors a really good clean ? My 15 GS wonder wheel becomes unresponsive from time to time, and a really good clean of the contacts between the two always sorted it out.
 
Mine died after less than a year from new (not a 1250, but same part). Exactly the same symptoms. Made sure I never sprayed water anywhere near it and bike has never been out in a bad downpour. Gave it a good clean but no difference. Dealer replaced the wheel under warranty in a day. I’m guessing you don’t have a warranty but is it worth asking if there is a goodwill replacement given it’s not too pricey?
 
I've yet to get out there and pull it apart.
It's a 2014 bike with over 50k miles, so I suspect a goodwill replacement is unlikely!

I suspect it may be water ingress? The garage build at the new house is not happening fast, so it now lives outside.

I don't think it's the GPS contacts as the HEX ezCan should let me adjust the brightness of the front lights via the wheel and that's not working either.
 
I can't help with the Hex ezCan part of your problem, but when my wizzy wheel started playing up, i was advised on here to do an update on the satnav, and it worked. Everything went back to normal. It might be worth a try doing the same update.

You might be pleasantly surprised if you ask nicely for a goodwill replacement.
My 13 plate GS had a new switch cluster fitted last year with a contribution from BMW. I sent an email to BMW customer services stressing the low mileage, FSH, and that it is garaged and not left outside in the rain etc etc. They liaised with my local dealer who replaced it. If memory serves , it cost me £220 instead of £450.
Be aware that the BMW FSH was crucial...without it they wouldn't have been interested, regardless of it not being a service item.
 
Looks like water ingress is the issue...

My bikes has a FJSH, BMW's input has been limited to parts...

Happy new year guys :beerjug:.

Back to reality.
This does not look too promising. However, sometimes, corrosion leaves a fluffy layer on the outside only, making shortcuts, rather than etch it's way into the print. If this is the case, hot running water and scrubbing with a toothbrush will wash it off. Then you make it dry again by using a vacuum cleaner, since it sucks out any water that may have penetrated under the components. Clean water as such will not hurt the components.
Water ingress as such does not damage the components beyond perhaps attacking the outside connecting pins, so if there is no visible damage to the outside, the component is most likely ok.
