BMW 2008 R1200GS question ?

[Bams]

Hi All
I went for a ride today and noticed no tyre pressure reading on dash, Yellow light ! on dash lit up, RDC and the flat tyre icon on.
My best guess is tyre sensor battery gone. (after doing some reading)
My question is if one sensor goes flat first they both indicate flat and show no reading back and front ? or has anyone had a different experience.
I would have thought that when one sensor goes flat you would see one tyre pressure ready ok and the one reading nothing.
I think it stopped working mid ride as I never notice anything until an hr into the ride.
I'm just wondering if I have a deeper problem than tyre sensors. Seems a great hassle to remove tyres and replace sensors to fined out a reboot would have done it.
Interested in others experiences with this issue.

Sounds expensive .....

See - just more shit you don't need to go wrong.

I have some experience. Maybe this will help.
The last time I got a flat tyre I noticed the handling went to shit and not long after there was a 'labia-labia-labia' sound so then I knew I was in for a cunt of a ride home :2thumbsup

You better buy a tire gauge ... to confirm the tire is (or isn't) flat ... ;)

In the "Old days" ... you knew when you had a flat tire ... :weep:

If a sensor is going flat a, it affects only the one sensor, b, things like the limit setting (ie, should warn at 24psi or less) also plays up, so mine would warn at 28-29psi.

If no reading is possible, pressure is shown as a dash. Earlier than that, it takes longer to give a reading than normal, ie, the good one will come up quickly, and the low one takes noticeably longer.

So I,m taking from what your saying you have had one wheel sensor pack up but the other wheel kept reading fine?

Yep, front one I think, wore out last year I think, bike is 2010 with 127k ish. Rear one still works.

Been doing a bit of reading online it might be because I left battery disconnected for a month or more and needs a simple rebooting to reconnect RCD to sensors or I have both sensors flat at same time and in need of a battery replacement and it seems easier to replace your own batteries than buy new sensors (no need to go to dealer to sink bike to new sensors)
Will have a go

GS911 will also do it I believe, unless you need the super duper tool that wakes the units. Definitely be careful leaving the modern bike batteries disconnected. A lot of electronics going on and they don't like not having power.

I've stopped visiting the dealers and now use Deano, an ex BMW tech. https://www.thebmshop.nz/

Replacing the batteries is a little more tricky as they're sealed into the units, you need the right batteries with the tab etc. Something I'll play with as I kept the original unit that came out of the wheel. Unlike the latest wethead updates, the camheads (and probably the oil heads) allow for 2 sensors per end (ie, 2 sets of wheels).

Thanks for that info . I had a look at Deano's web site you sent ,he sounds like a good guy to know I have often driven past his shop a number of times and wondered about him .
Looking at the You tubes on battery replacement it seems like they are having success with just soldering an off the shelf battery its just a standard lithium battery and gluing the back up . defiantly worth a go.

I think I meet you on mid winter madness ride 3 or so years back you where selling your GSA then if this is you ,you kept it? I was on a blue GS

I did the 2012 MMMMM ride (fark, tis a wee while ago). No, definitely haven't made any move to sell and don't plan to. Most likely to run it into the ground and buy another camhead as I've got custom bits that only fit the 2010-2013 R1200GSA amongst other mods.

Deano is a great guy, ex BMW NZ and ex Experience, plus you're supporting him direct.

Yep Then I think you should have your GSA for a long time then, I imagine if stored in a shed these bikes should do 300,000km plus with little effort.

Ah - not without lots of coin replacing bits. They don't get fixed with your favorite hammer like the old ones.

Go on, ask a honest owner with decent kms on them what they have cost ....

Does not stop them from being good bikes, like anything now days they are complex. Includes modern women. Very complex.

That was an awesome ride! last MMMM I did 5 of us came off on a patch of black ice so haven't done another winter version but we did do a Summer run from the Napier Taupo to the lake.

Distinctly remember seeing your Beama and thinking it was pretty sorted! even took another shot of it

I have a 1999 1150GS and my automatic boot sensor never fails. Just ... kick the tyre before you ride. My arse sensor comes into play to detect on the run deflations of the rear tyre, and my heart sensor is always at hand to indicate front tyre deflations.

I think you might be on the wrong forum for this question there has been a lot of discussion on the tyre pressure sensors try a serch
