8000 3601 is EU, RON 95 & new injector
Part No 07658860 - 5000 3611 is EU, RON 95 & old injector
We have Haakon to thank for taking a pic of the old Moditec Dealer System screen when he first purchased his GS & was with the Dealer tech in the workshop, it had a table setting out the firmware versions/injectors for all of the single spark production, FYI the 5000 Series only went out to EU markets in the first batch of production, BMW then realised their error, there are a few here in Oz as we get EU spec machines
I am a little surprised re the Mfr Date of 1400-04-10, it is usually correct, is that a typo ?
Re a BMW updating the firmware to the 8000 series & messing up the VIN, I assume a Dealer not BMW AG ?, having a different VIN will not affect operation but it should have been easy for the Dealer to change the VIN to suit the bike, cant imagine what silly stories they would have tried telling, BMW have put incorrect/invalid VIN's in some bikes during production, we have a dual spark in that boat here in Sydney, GS911 picks up the incorrect character in the VIN the Dealer system does not hence it was never corrected to match the compliance plate on the frame
Re running 5000 series & a new injector, Haakon did try but encountered problems, he realised later he had failed to do an adaption reset/rebuild & unfortunately he did not have the opportunity to try again
