TheMK –

Thanks for those newTIS links!

Drilling down to the i3, there are a LOT of subheadings that seem to make no sense whatsoever. "28 Twin-clutch gearbox (DKG)"? :lol:

I think my problem is with the plug locking mechanism, but I decided to take it to the dealer before tackling bumper removal.

A note from the dealer drop-off...

They have seen this issue before and suggested that, not only could the locking plunger be at fault, failures of the control module and/or the interconnect between the two have been observed.

Once I get the i3 back I'll update this thread.

61-13-6-842-870 (High Voltage Charging Socket, Central Locking Drive) had failed. With a new one installed by the dealer, I'm now 2 for 3 in high-speed charging (versus 0 for ∞ before the repair).

Today I ran into an issue with an EVPump EVSE. The i3 locked the DCFC cable to the car (as expected) but the EVPump EVSE stayed in the "Communicating With Vehicle" state for five minutes.

Had to use the i3's manual disconnect to get the cable detached from the car.

Any ideas why this EVPump unit would accept my credit card but would time out in communicating to the i3?

Pure guess… Negotiation communications occur over the top pins in the J1772 connector. A CCS plug and cable can be so heavy that the plug can be pulled down which could break the connections of the communication pins. If communications problems happen again, try lifting the plug until communications have completed successfully and charging has begun. Some have reported success when doing this.
