Di2 known issues

Following on from the spat going on in Workshop about this Di2 stuff, let's have a convenient place to post issues and hopefully resolutions to users' problems with Di2.
If you want to crow about how useless / pointless / overpriced / poncy they are, start your own thread and do it there if you don't mind.
My issues turned out to be a corroding cable plug at the BB junction B, fitted in the most ridiculous place possible for sensitive electronics.
Other known issues from that thread:
Batteries aren't that robust and can succumb to extended exposure to cold
The waterproof seal where the cable enters a device (FD, RD etc) isn't waterproof if the plug doesn't properly latch into the socket. The latching mechanism isn't overly robust, esp if grit or sand gets in when trying to reseat it. Best to only do that in a clean environment, not in a farmers gateway or on a dual c/way in a downpour.
Knock on effect of that is that the connectors can corrode if road water etc gets onto them and isn't cleaned. So occasionally unplug things, eyeball them and clean them. Lots of electrical cleaning stuff is readily available in places like Maplins.
Like any other electro-mechanical device, things can break. I know of two RDs that have apparently failed, based on the system working correctly again after their replacement. Maybe RDs are not well built, who knows?
The battery mount is occasionally reported as the source of untraceable faults. Unfortunately substitution seems to be the only way to test & fix this.
