I?ve got a 2004 R1150GS with 15,000 miles. Replaced the battery with a new BMW gel battery at about 13,500 miles. About 4 weeks ago I returned from my daily commute and put the bike away for the night. When I returned the next morning the bike would not start. It would crank but it would not fire. Initially I thought it may have been a fuel problem because lately I?ve noticed that it would knock and ping around 4000 RPM. However that was not the case after draining the fuel and replacing it with fresh fuel it still would not start. Checked for spark and noticed that it was intermittent at best.. At that point I took it to the dealership to let the pros with the diagnostic dohickies figure it out. They first thought it was the HES sensor and replaced it with a new one. Still dead. They thought it was the control module. The new one being $1300 the dealership wasn?t willing to take the gamble of getting stuck with the part so I suggested used from Beemer Boneyard. Ordered and installed?. Not the control module and after 4 weeks my GS still sets at the dealership with intermittent spark and fuel.
Has anyone else experienced these symptoms and if so what is the remedy?
Any ideas, suggestions welcome at this point!
