I did see recommendations to clean the sensor, but my sensor seemed fine. Maybe that mindset caused me not to even look for a fill plug. Glad to get the inputs.
I'd like to know what the lube the splines interval should be.
I did a quick look thru the Maintenance Schedule [printout from the local BMW dealer for the 08 12GS] If you go thru water, it makes sense, but otherwise...
