Went to go to see family in the GSA this morning and it wouldn’t start. Error message on TFT and zero juice in the battery. Still waiting on BMW Assist who were meant to be here an hour ago!
Epic!
Epic!
Bike let me down this morning
- Thread starter RallyeGS
- Start date
Assume it's always kept on a trickle charge?
It wasn’t no. I must have missed that bit in the owner’s manual!
Hopefully it’s something that simple.
Normally they go into limp mode if a fault detected but it started earlier then nothing so sounds more like a connection issue. Something like a battery or earth lead loosening. Good luck 
and let us know when it’s diagnosed.

Why do you assume? I've never ever used one. I can't understand why it should be necessary? It's there a fundamental problem with the newer bikes?

This will save you if battery is very low, but if battery has dead complete only new battery can help, more cheap online but this never fail in few years and used many times on friends and even me.

Not needed if bike out often and more than 1 hour good ride
Chap that recovered the bike, says he deals with battery failures on 21 plate GSs all day!
Shame he didn't just bring a new battery with him....job done.
If tracker had drain battery battery can be jump start no problem, but if battery dead, it is dead my friend had dead battery few weeks ago, no possible jump start, we change battery and all was good.
Because they now come with trackers, which are quite power hungry. Really, the dealers need to be advising people when they buy these bikes, mine did, though I'd been already aware of the issue. Fitted alarms add to the mix.
btw, you can set up low battery alerts using your datatool dashboard.
Don’t believe mine came with a tracker, bought new 4 weeks ago. Is there an obvious way to check ?
Mine has a Biketrac. The consumption is very little - the tiny internal battery was still active more than two months after being disconnected from the bike.
In my experience, it's a myth that they flatten batteries quickly.
I think it's fair to say that there are some varying thoughts out there, though also claims that the datatool is quite hungry. What I would say is this, I had no problems with the battery on my 1200 that simply had an alarm fitted, but that during cold weather and having forgot to keep my 1250 (alarm plus tracker) on charge for just a few days I found that I didn't have enough charge to turn a month old bike over.
Now, it could be that BMW has downgraded the battery or something else to do with the electrics on the newer bikes, but there's plenty out there on other bikes to suggest that certain trackers do hit the battery.
I guess the bottom line has to be, why not use a trickle charger regardless?
Exactly my situation
