Cabin overheat protection, how to?

Hi everyone, I’m confused by cabin overheat protection. It seems to be linked to the tilt alarm. One can’t work with the other. But my tilt alarm is greyed out (it’s on, just greyed out).
So how do I proceed ?
 
When I check the manual, there seems to be some reference to tilt intrusion as part of the alarm, which we do not have here in the US (at least I dont think so). Perhaps there is some combination that includes tilt intrusion on international vehicles that prevents cabin overheat protection from activating?
There is tilt intrusion on our cars. Very recently I had a service come out to my house and do tires for me, they used 3 jacks and se-sawed the car a little and the car alarm went off.

Yeah this thread is confusing me...
Yup... that's Tesla reality for you. People with different software versions (and nationalities) get different results. When our North American brethren chime in on a UK & Eire forum, things get muddled. With the latest update, Cabin Overheat Protection seems to be working reliabily, touch wood.

For me. Today. In Spain. Full moon in two days time.

I do beg your pardon. Numbnuts here posted it on the global Model 3 community forum. But the sentiment remains over in the UK space on this board. Perhaps forgivable since the temperature rarely exceeds 41C back in Blighty so insights might be rare from the home team.

Yeah my wife has a M3 and sentry mode and cabin overheat protection is controlled by app with no problems but with my MX, I have to goto car, turn on COP and then turn off sentry mode and leave car, then I can turn it off with app and re enable sentry mode but not visa versa?

anyone the same please?

And yeah I disabled tilt and turned off sentry mode, turned on COP and left car. Thing is I can then turn COP off via Tesla app turn back on sentry mode but not sure why we can’t do this I’m reverse?? On M3 you can with no problems.

If you set it to just fan and no AC, it could be engaging but incapable of going down to 40C.
That's how I have it set to and today, watching the inside temperature after leaving my car, it crept to 44.5C and is staying there for over an hour. Audible check of the car and the fan isn't spinning. Looking at the data from the Climate info returned from the API, I can't see anything mentioning COP was active.

So, according to the inside temperature, and parked for just an hour at home. charging with Sentry off at home, the fan should be ON, but it's not.

For all you EU friends, just checked it out and
without tilt turned off and sentry off it will not
cool the cabin. We tried to turn sentry on with
the phone app, it turns on tilt as well so that appears
not to work. Not hot enough today to see if plugging it
in will change anything. It seems its hard coded.
We could not find tilt in the phone app so we had to
do it in the car. We are on the latest software.
For the sake of completeness it turned on at 42C.

Just came from a ride about an hour ago. It's 32C outside, sunny. Car parked with the windshield facing South, Car is awake and charging with SoC at 73%. It's 49.6C inside. No fan to be heard :-(

Beside the different temperature, data is the same as yesterday. Fan Only definitively has issues unfortunately.

Yesterday cabin cooled fine. Today it did not work,
the fix seemed to be to turn it off and on (cabin protection)
with the cell phone, wow that some funky software.

I have a sneaking suspicion that the fan only setting is not working in my car also...

Please explain how you manage that. Mine will not activate overheat protection if Sentry is on. I can’t disable Tilt Alarm if I use Sentry. Catch 22?
I don’t do anything to manage it, they’re both enabled and they both operate at the same time. I know this because I get cabin overheat notifications while Sentry is active. I don’t have the tilt/intrusion alarm in my cars, so maybe that’s the difference.

For the ones that still have the issue of Cabin Overheat Protection greyed out, what worked for me is:
Try to enable dog mode. Then the COP will be able to get enabled.
I did that via the mobile app (Android)
Note: for my M3 in Greece with version 2023.12.9 I cannot have both sentry mode and COP enabled.
Anyway this seems to be a bug that Tesla needs to fix.
