Post by: WayneC on June 11, 2015, 03:05:46 AM: The codes are telling you the fuel pump overloaded the fuse with excess current which presumably blew and so fuel pump circuit was then open circuit.

Since the faults are not currently present I assume the fuse was replaced

Beyond that I will leave it to others who know the K50 better than I to comment further

Post by: backdraft on June 11, 2015, 05:05:16 PM: thanks, managed to get one locally, very similar specs on flow rates for $110 CAD which is $80 US.

Little spending but don't have to wait for shipping.

Surely the K50 is still under warranty? Or am I missing something?

Pathetic behaviour by BMW, what are the RTW guys expected to do ?, return the bike to their home country to claim warranty ?, I dont get their attitudes
