Charging port not opening sometimes

Hi,

I have noticed a frustrating issue lately, not sure if it's since the last update. The charging port won't open from the home hpwc handle button when I get home to charge. However the button works to unlock the port before I leave in the morning. I am sure it used to open when the car was unlocked.

The only way to open the port is to open the app and go to the charging screen or via the touchscreen meaning getting back into the car.


I have a 2105 model S P85D
I have reset the mcu, twice
I can unlock the port with the button on the charging handle on completion of the charge with the car unlocked
I have the key in my pocket at the time

I have not tried another charger or supercharger as none close by

Any ideas?
 
2105 model s - is that future model better than what us mere mortals get?
I’ve also had this problem With random not working. Booked in a service and the charge port door was ‘recalibrated’, which solved it.
You should also be able to open the model S charge port door by pushing on the charge port door left hand side. There is a slight delay. You can also disconnect after a charge by pushing the little black button on the left side.
Note car must be unlocked and awake for the single press. If unlocked and asleep press twice.

If you have a V2 HPWC they are a bit notorious for the wire that powers the button in the handle failing. I understand that the same wire is used for communication between the HPWC and the car, so as the problem get worse you may find that the HPWC can’t communicate with the car and you will get a red light on the charger and an error on the screen saying no power detected in HPWC. Pressing the reset button will fix it in most cases. You can test this next time it happens by holding down the boot opening button on your fob to open the charge port. if it opens then the problem is with the HPWC. I’m guessing that it always works to unlock as it is powered from the cars charge port.
This is happening to my V2 HPWC and I managed to fix it by carefully recoiling the cable over the HPWC so as to reduce as much twisting of the cable as possible. I was lucky and it now opens the charge port and I get fewer red lights but it’s only a matter of time before I will need to replace the HPWC.
 
Thanks for the replies,

I've tried a few things.
1. Using the button on the remote, app, car touchscreen, and the UMC open the charge port to charge every time.

2. Using the HPWC no longer opens the charge port, however on completion of charge it will unlock it

3. The suggestion above to press on the left of the charge port doesn't work, and when opening don't see a little bleeding button either, this might be on newer models

4. HPWC never had a red light on It, I did reset it and left the isolator off overnight and no difference. Most of my cord is coiled over the unit as I only seem to use 1.5 m or so to charge

My HPWC is probably closer to 3 years old, and most of the time it's plugged in to the car as its only been a weekend drive if that. Only done about 15,000km so disappointing if its failed in that time in little use.

Ill stick with the remote option for now until another problem shows up with the charger.
 
I have an X and two S models. I have two HPWC. Either HPWC will open the charge port on the X or the older S. The new-this-week S will not respond to a signal from either HPWC. A signal from a fob or from the Tesla App will open the port, too. I conclude the problem is the new S, and I will report this.

Your charge port door needs to be calibrated. You should be able to double press on the left of it to open as well
 
Thanks. Manually pressing on the charge door DOES open it, but not the charge handle. I will let the SC sort it out....unless there is a way to calibrate it that is not obvious.
There is a button inside the charge port on the left. Press that to release handle. Car has to be unlocked first though. Calibrating has to be done by SC. I just press the chargeport door. Even after calibration I can’t be bothered doing the tesla model s charging dance.

I stopped at a SC yesterday to confirm that the door does not respond to a click of the charge handle button. So, it is the car, not my charge handles.
