I am also looking for this adapter (roadster to EU standard ), anyone happen to have this adapter for sale in Hong Kong? I also sent an email to Henry @hcsharp to get a quote for a brand new one. Thanks.

Dear Roadster owners, and Tesla enthusiastics, I've recently encontered some problems with my roadster. It starts with a brick being unbalanced (3.76V min vs 3.97V max). So I decicded to have this brick rebalanced. After transport the vehicle over 1200 km from Shenzhen to Hangzhou, the vehicle...

Just want to give an update about the vehicle. So the VMS was indeed the cause of the problem. After I put the VMS back into the vehicle the VDS can finally talk to the VMS and enter the service menu. The "VMS-VDS comms fault" is gone, and VDS no longer asking me to set a new PIN. Well...

I am really lucky to have Mark helping me debug the VMS and eventually managed to locate the problem and solve it with his amazing skills. It's amazing to still have those talented people like Mark and others (Spaceballs, ML Auto, Gruber etc.) around and help save so many roadsters. I'll keep...

Thanks for your help. Yes I did hear the pop sound when inserting the service plug, and the slight click sound of the microswitch, so that all seem fine. I managed to drop The VMS (thanks to ML Auto for the instructions), and opened up to check the LEDs. I disconnected the 2G modem as ML Auto...

Forgot to attach some photos... I also noticed that there's only one metal spring contact inside the ESS service socket (see attached photo), is this normal?

So I finally received a brand new service plug from Tesla SC. However when I inserted it the vehicle still shows the same problem - VDS screen showing a "VMS-VDS comms fault", but nothing else works. OVMS is on but not providing any information about the car except an 11.8V voltage (from the...

Vmin is consistently brick #29 regardless of ESS being empty or charged, Vmax varies.

Is that fuse rated at 0.1A? I think the brick went out of balance due to bad charging. I do not have a dedicated charging facility, so I use public EV chargers, which automatically turns off when fully charged, leaving no chance for the BMS to balance the bricks.

What's the maximum charging current if I were to bring the brick voltage from 3.7V to 3.9V? I can see the max 100mA charging current on the board but I think that's the current limit to save a brick from dead right? The traces on this BMB board and the connectors should be able to handle a much...

Hi Mark, I see that your location is Hong Kong, my roadster is also from HK. I am wondering if it's okay to have a chat with you just to ask a few questions about the car? Huge thanks!

So I supplied the vehicle APS with an external 12V power supply. Some part of the car starts running, the cooling pumps are pumping, the VDS screen lit up, all the shift buttons illuminate red. However, the VMS did not seem booted as the VDS still shows the same VMS-VDS comms fault, and could...

Dear ML Auto, huge thanks for your help! I'll give it a try later today. I love this community!

Thanks for your reply! You're right, the service disconnect handle is indeed broken and that is one of the reasons the car does not start. However, does the VMS boot in this case? I'd thought the VMS would still power up to tell me that the service plug was not inserted properly. I do also worry...

I then thought could it be a fuse blown due to the high current surge to charge the low-voltage 12V battery when I put the ESS disconnect back in? If that’s the case where should I check and replace the fuse? Any other ideas about what is going on? Thanks for your time!
