I've got a 2010 R1200GS Adventure with 8500km which I bought new and have been having a great time riding. Last night the fuel gauge (and range reading from the onboard computer) suddenly started giving really erratic readings - over a 20km ride with less than a quarter of a tank giving readings of over 3/4 to less than 1/8th and back up before finally settling to what I *think* may be close to correct. Up to this point it seemed very accurate and reliable. Contacted my dealer and they weren't overly suprised and said they would "recalibrate" the fuel strip. I've read through several threads here about this issue and in general it seems that recalibration is a temporary fix at best and in many cases doesn't help so they end up replacing the strip... So my main question is this: is recalibrating the strip just a waste of time - ie: should I just push the dealer to replace it now (since it's on warranty anyway) in the hopes of saving myself the hassle of having take it in several times? Anybody out there had this issue, got the strip recalibrated, and that solved the problem permanently? Secondary question: anybody know (not interested in speculation) what would cause these things to go out of calibration in the first place? FWIW, I avoid ethanol blended gas... Oh, and please don't tell me to just use the trip odometer - that's as helpful as telling someone with a defective seat to just stand on the pegs. Anyway, I've lurked and learned a lot on this site in the past, and am hoping for some good guidance on this, so thanks in advance!
