Re: Charge door no longer locking and unable to CCS charge now

Mon Feb 11, 2019 1:15 am

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.

... it seems to wear out and need replaced every 3-4 months.
Has anyone had this issue and arrived at a solution which worked long term? Or, for a sanity check, are there other folks who are changing their charge lock more often than their brake fluid?

I replaced my charge socket lock (61136842870) about 4 months ago because it was getting stuck in the locked position on my home L2 charger.

The new one worked for a month or two then stopped locking. That's not an issue for home charging but I did want to address it to allow DC Fast Charging. I removed the "new" charge socket lock from the car and tried to manually turn the "emergency" arm to extend the locking pin to no avail. I was putting a decent amount of force on that arm and only held back because I didn't want to break it. Even trying to assist by "pulling" on the pin with pliers at the same time didn't work.

I tried jumping the lock with 12v across the outside pins and could tell there was a slight jerk, so the motor was trying to do something but no movement whatsoever. Even after opening up the mechanism, I couldn't get anything to move any of the gears inside in either direction. Finally, I removed gear #2 and then things started moving when I put 12v on the motor since it was only connected to gear #1 in the picture.

If I ran it like this for 10-30 seconds it would eventually stop and it seemed like gear #1 was binding in a way that was jamming the motor.

Long story short, I reinstalled my 'old' charge socket lock from the previous time (with the cap from the new one) and so far (3 lock/unlocks with the charge cable connected), it's working correctly. I just don't particularly want to have to do this again in 3-4 months. And more-so, I don't want to have to do it again in 6-8 months possibly in the freezing cold!

According to BMW, the proper way to access the charging socket plug is to remove:
1. the rear bumper
2. the wheel arch cover

After you do that, then you can access the charging plug. If you don't mind doing the disassembly work, then you shouldn't break anything.

Here's the repair instructions from BMW:

For what it's worth, you do have to remove a lot of stuff to get to the charge socket lock (remove wheel, inner fender, etc.) but it's all fairly simple with one exception. This is a good video that shows the steps, though it's a European i3, so note that the the charge socket lock will look different and be oriented differently on a US i3.

Around 4:20 he shows the only part I struggled with. You have to release some tabs which you can't see, and the charge port hinge really limits access to the forward side. Be patient, and it's possible to do but I was tempted to just break it and buy a new one a few times before I got it to pop loose.

I had a problem with the charging lock actuator on my i3 about a year ago. Ordered the part (61 13 6 842 870) along with two unique fastener screws, but they took so long to arrive that I no longer have the i3.

I'm happy to offer these to anyone willing to pay for the shipping.
