Di2 misbehaving

My Di2 has started to act up. Full battery but will only shift when it wants (both ends). The lights also just come on and off as they please while I'm riding.

Another strange thing about it is that it won't work at all when the bike is upside down, only when it's upright. Could this point to an issue with the battery itself which is in the seatpost?

    sounds like a loose or corroded connection. failing that do a firmware upgrade just in case. or check and do firmware upgrade anyway.

    I'll book it in, haven't got a PC so can't update the firmware. Reckon it probably is a dodgy connection though.

    You can use the etube app on an iPad if you have the wireless sender wired in...

    Update the firmware. If that doesn’t sort it, get SRAM red eTAP

    You think replacing the entire groupset with a completely different system is a valid suggestion, Nick?

    He probably has a spare one in his 40kg backpack :lol:
