I recently added an EVchargeKing Tesla Button to my tethered PodPoint charge point at home.

When it didn't seem to work very reliably (at least the remote opening of the charge port anyway) I assumed I'd probably done something a bit wrong, and would need to pull it all apart again soon and check my soldering. FWIW it has always reliably interrupted charging and released the locking pin as expected.

However, I've just come back from a loooong trip that involved no less than 10 different superchargers, and hardly any of them managed to remotely open my charge port either. Seems to work about one try in ten, but not more.

Has anyone else had a similar issue? Is there something obvious that I could be doing wrong? Or is it one for the snagging list?

Timsk, there are lots of posts about this. It frequently seems to be the charge port rather than the cable. The small round button inside the charge port opening (once the flap is open) appears to be a magnet. That is all that keeps the flap shut. The flap sticks to it. It can be forced apparently, without the risk of damage, as it is only magnetism holding it shut.
Several remedies suggested, including a bit of grease/oil or similar on the magnetic button that holds the Flap shut. So every likelihood that your buttons are fine, but a non-opening flap is certainly NOT a new problem. As a last resort, a bank card at the point of the flap (by the magnet), followed by sharp blows to the rear of the flap sometimes works, they say.

Push on the very rear of the flap, behind the hinge point, whilst operating the key or other flapping mechanism.

I've never worked out how the button works. Does seem quite random but it may be because the car locks before you have time to open the port. I think it needs to be unlocked to work?

Thanks for all the replies. Now you all mention it, I do vaguely remember reading something about non-opening flaps ages ago, while I was still waiting for my car, but I'd forgotten. Ta for the reminder. :)

The charge door on my first Model S worked perfectly.

The one on the P90D is a pain. Fails to open as often as it succeeds.

Don't expect this to improve in the near future; the US cars now all have motorised charge ports so there's no way TM will invest any time redesigning this part :-(

Use a rag and clean the port every now and then. It seems to help mine be a bit more reliable.
Thats the most effective way!! Use the rag to clean the magnetic contacts
AS for the charge port opener on my UMC, I have the same issue as @mgboyes , but it opened today with the first press of the button, not sure whether its a coincidence or not?

The odd thing is though that it always opens first time when I do it from the touchscreen or by holding the button on the key. They're my failsafe options when the supercharger button or my DIY-installed button doesn't work.

I'll certainly try cleaning the magnet and possibly putting some electrical tape over it to slightly weaken its grip on the charge port door, but I don't understand how it can open remotely from the touchscreen or key but not from the charge connector button.

In my case I'd say 2/3 of the problem is the signal not being picked up (and with the onscreen button, or fob, this isn't a factor) and 1/3 is the port itself sticking.

I saw a comment somewhere that there was some sensitivity around where the head of the unit is in relation to the back of the car when button pressed. So it might be worth waving it about when button pressed.

I was coming to the same conclusion. The fact that one over-powerful transmitter can apparently cause all the charge ports in a row of Teslas to pop open means that there's a receiver for that radio signal that separate from the one for the encoded key fob; and if my car can't even pick up a signal from a transmitter that's right next to it (but will respond to the key fob) suggests that there's a problem with that radio receiver.

I'll mention it when it's going in for a service, and in the meantime just wave it about, as Royz suggests above.

Used my UMC button this morning.
It didn't work!
Unlocked the car again, it didn't work!
Used the key, it opened.
Conclusion: The UMC is pants or broken :(

As you probably know I do not have this problem I just reach into my boot and press the secret button and all charge ports in this sector of the galaxy open☺

We also noticed the charge port wouldn't open using the button on the Superchargers last week. I don't think it is a charge port issue because it opened reliably using the dash or key fob. Maybe just a glitch?

I reported the charge port not opening properly at superchargers last month when the car went into Manchester for a few jobs doing.

After they had a mess with it, it does not open at all now, always got to use the key fob, back in next week again

I would recommend buying a "stegen" remote control - it works every time as it sends out a signal strong enough to travel 100ft or more - you just need to find someone who accidentally bought a batch of 10 (the minimum quantity) & is looking to sell the spare ones off 1 at a time, or start a thread to form a group of 10 to share it out. £18 each + postage
