I got this message last week and took the bike to my BMW dealer. They said the last guy who came in with this ended up with a new bike.
Mine has been diagnosed as needing a new exhaust manifold and the error codes ultimately related to the fuel pump which they are not going to replace as all seems okay with it. Will get the bike back next week and see how if runs then. This is the fourth time it has had to go back due to error messages like this and I am getting a bit fed up with it if I am honest.
That said, the dealership have been absolutely brilliant throughout with first class customer service. I have also really enjoyed the loan bike - S1000R! Want one. Perfect companion to having a GS.
