Odd fuel gauge

[neo]

Ok so i fill up fuel gauge goes up.. 10 miles later sudden drop to half, 20-30 miles later down to 1 segment lit!, refill get about 18 quid in, I was rather hoping to achieve 200 miles to a tank, it's a 1200 gs non adventure, I have heard you can get the fuel gauge "re-calibrated" can anyone elaborate on this or do I need another sender? Or what?? And advice would be great and thanks in advance, also as for the mileage (cough) 72,000 (cough) good history tho, only had her a week hence the post, just changed from my 1150 gs (hoping not to spark a "why'd you do that for" debate)

Sorry to ask a daft question. Just to be clear are you saying you filled the tank to the brim, rode about 30-40 miles & it was half empty?

Welcome
The search function will reveal lots of info
I just zero the trip when I fill up

no i filled up and rode around 100 miles without the fuel gauge diminishing (sorry i missed a zero off) , then i just drops to half, then in about another 20-30 miles it drops to about one cell showing before the last cell... i will search the forum on this matter now, many thanks

Mine does the same.

Trip buttons reliable at least.

They all do that. Just fill it up set the trip and in about 170 to 180 miles start to look for a filling station. Don't start to panic if you can't find one straight away as you do still have a good twenty miles left in the tank.

Honest try it.

You will get between 180 and 210 miles on most tank fulls - some time more - sometimes a lot less

Ok I will do this many thanks, I can't see how such a well talked about and expensive bike can have such a fundamental problem, seems there plagued with this. Come on bmw sort it out!

Fuel gauge is an expensive way to avoid fitting a main/ reserve fuel tank. Trip is annoying because it defaults to total miles all too easily.

Mine stays on whatever the last trip setting was until I change it or disconnect the battery. I think it onlyu defaults to total miles if you don't let it go through its check cycle when you turn the ignition on.

As I said it defaults too easily. Also you can't safely change the display without stopping. The button is too far away to reach safely. I don't see why the miles display can't simply stay put until I choose to change it. No mechanical odo would mess about and is far better for that.

Can't see the problem myself - just turn your ignition on while you're putting gloves on if it worries you that much, it hardly takes very long does it?

Of course it's no biggie but Someone went to all the trouble to program it like that. When was it ever useful? 3 out of 4 times using the bike it's fine then you forget & ride away. Sod's law that will be when need to see the trip.

Use the bike a lot and it does become an issue.

From a programming point of view its always best to put the important stuff in first on an initial power up - such as brakes/ ABS checks. I would think the BMW engineer responsible for deciding what the trip defaults to didn't think it quite so important so left it to the end of the 3 second cycle. Plus its hardly difficult to press the trip button at the first set of lights if you forgot

I just scroll to the trip I need using the button on the left hand controls

You sure you're in the correct section?
