Ahhhhh.....pressure sensors
Sorry, but if you can't tell the difference between a flat tyre and a fully inflated one, you deserve to be stranded in a strange place
Did you have Nitrogen in the tyres?
Yeah, but it's only flat at the bottom.

Air goes down the valve stem, through the valve and then through the monitor into the tyre space. I'm thinking if the stem snaps off, the TPS monitor will still see the pressure around it, but the wheel will need a new valve. Putting the monitor back inside the rim with velcro might still work unless the valve stem itself works as a radio aerial.
Its just an idea. Ive never tried it.
Yep... think you're right.

Bit old this one to bring back but I'm wondering if its been tried yet (normal valve and tpsm stuck on inside of rim). Mines just broken and been quoted £200+ at my local dealer to sort it out. Some place on flea bay in Canada and Spain are selling original (probably not) ones for £36. Obviously would need coding in (wonder if GS 911 can do this, have seen a screen pic showing RDC panel)
Have seen some pics of the large part of the sensor without the valve part so I guess the valve pushes through the sensor, through the wheel and a nut holds it all in place. if thats the case the I wonder if its the large black bit that senses the pressure as well as transmitting it. If that was the case a car valve, like say of a Focus with TPSM, would do the job as its job is to put air in and hold all in place. Any thoughts?

I bought one of those Spanish EBay sensors, looks genuine enough. Not had the tyre off yet to fit and try it out so I can't confirm either way.
If you are thinking of fixing a TPS with a broken stem onto the rim, do bear in mind the centrifugal force trying to throw it away from the wheel will be very strong at speed, it follows square law, double the speed quadruples the force. Velcro might not be enough.

Hi magwych, look forward to hearing if your Spanish one works when you get round to it. I'm in no rush as leaving bike at home and heading south for a few weeks. I wasn't gonna use velcro, was thinking more like ararldite. I'm guessing the sensor will want to fly away from the centre of the wheel and the rim obviously stops it so araladite should hold it.
If the Spanish one works that would be the option Id rather use. Seen an American site sells OEM for $132, seems better than £200 even with import costs.

Got an update for this thread. I've managed a temporary repair in terms of cost, not time. My brother in law is quite inventive and came up with a solution. We removed the wheel, popped the tyre off its bead on one side and with use of thick cardboard and a quality tyre lever levered the tyre back over the sensor. Then placed some wooden blocks between rim and tyre to allow the sensor to be removed. We then countersunk the sensor from the bottom,drilled the broken stem in stages, inserted a mountain bike presta valve through the entire assembly covered with a flexible sealant then refitted it. Did take some pictures but can't post as not a subscriber. Only downside is I have to use a track pump to put air in the tyre. Total cost of around a fiver and a couple of hours.
The inserted valve has a cone shape to it which is why the sensor was countersunk, this would seal on its own and the sealant was belts n braces. Mountain bikes run over 60 psi these days so I have no worries about its capabilities. When I get a job up here (just moved) I will replace it properly. When I finished this I noticed my rear esa is leaking! Not sure what repair to do on this one!

I finally fitted that back oin October, and have done a good 5000+ miles on it, and it works fine. They appear to be the genuined article, but do not have the unit ID printed on a label, so the pairing process is a bit complicated, I couldn't get the GS-911 to do it, and ended up asking my local dealer to do it.
We are talking about the little valves that allow air into your tyres here,and not an engine rebuild,are we?
Yes, we are talking about what BMW do best!!.
It's another unnecessary complicated gadget to go wrong and cost loads to fix. How the feck did we manage for years without one on the bike? is it really that difficult to check pressures with an ordinary gauge? It's like these fancy electronic suspension systems they fit these days, gadgets and gimmicks for the bone idle and victims of marketing hype

Is that as, in teaching owners not to check their tyre sidewall for splits, which may cause the tyre to delaminate when you least need it too. Because you no longer need to check the pressures , kind of best.

Good repair. It's also possible to replace the TPS battery. I've not seen them for Presta valves, but pressure sensor valves (or any other type) wont break if an angled adaptor is used.
The issue of ESA shock rebuilds been covered in the last month or two. Alternatively, fit a Wilbers WESA at about 4x the cost but a much better ride and it's built to be serviced. I've ridden a (non BMW) with Wilbers back shock and IMO its well worth the money. Its such a shame BMW did not offer them as options when the bikes were new. Especially as they used to use Showa units.
By the way, Ive had GS alloys on my GSA for at least 6 months and still not got around to having them coded to the bike. Apart from the amber warning triangle Ive not missed the TPS reading.
But Ive not been riding anywhere that's likely to get the tyres damaged. I'm sure a quick run over stony unmade roads would have me being a lot more concerned.

Its a secondhand bike and fitted to it already so didn't really have a choice.
Windychuffer, I did put a normal valve in it to move it around. I didn't leave it in because I don't really want to ride around with a warning triangle flashing at me constantly, annoying and I might miss another warning. Bmw dealer told me it would be an hour to an hour and a half labour to switch off the tpsm sensor...if they could do it. Can't see how it takes an hour or more to press a few buttons on a computer but hey ho, it might run windows!
Had a bad experience with Firefox racing, they were uksuspension then. When cash flows forth I think I'll try MCT.
My Buell X1 runs aftermarket pressure sensors in the rims and they are attached by a giant jubilee clip holding the sensor into the well of the rim , there is also a small steel bridge piece that goes over the valve stem area to prevent the clip stopping you inflating the tyre.

Thanks for a pleasant reply.Why the ffs? What do I need to let go? And what do I have to do to live a bit?
All I did was give people my solution to a common problem. Didn't realise that contributions weren't welcome, my apologies.
