Two questions about the locking mechanism
I fueled the car with my wife still in it, it doesn’t trigger the alarm or anything.

I fueled the car with my wife still in it, it doesn’t trigger the alarm or anything.
1. I come down to the garage, enter the car (unlock it by touching the door handle). but before I start, I simply wanted to shuffle some papers in the glovebox. after like 30 seconds, alarm was triggered due to movement inside. completely stupid and unnecessary. all this time, I have my key in my pocket. the car should detect that the key is inside, everything is under control. i am disturbing neighbours, FAIL. Solution: should have opened screen, click on car menu, swipe right, untick Interior monitoring...
2. some other time, i go to the garage and directly try to open the trunk using the handle, with the key in my pocket. the alarm is triggered for half a second (loud noise) but then the trunk is being opened and alarm stopped. most likely car was 'sleeping' from what I read in other threads. Solution: I should have unlocked from key to 'awake' the car, then proceed. so even if I have keyless entry I cannot trust it to work as it should every time. my previous non premium car never did this. FAIL
3. I stop for filling up. my wife and one child stay in the car. the oldest comes with me for a quick leak. I knew that I should disable the stupid interior monitoring (see the 5 steps at point 1), so ATA is not triggered. key is in my pocket the whole time. i fill and enter the gas station to pay/take my son to the toilet. my wife decided just to open the door and help my younger one in the back with something, alarm is triggered.... because car was not locked, but ATA was primed. FAIL
4. again, stop at gas station, I instruct everyone to act paranoid and not move/touch open anything while I fill the car. I proceed with the 5 steps at point 1. I take my other son with me this time, the two other passengers stay in the car and behave. when coming back, my son runs ahead of me and tries to open the door, i was lagging behind a bit. of course, key was not in range, alarm was triggered. FAIL again!!
5. I don't reiterate the episode at the tyre shop. there I disabled manually (the 5 steps the interior monitoring and towing sensor). but since the valet whatever moved the car several times (started stopped the car several times), the settings are reset every time. due to the car being raised several times, towing sensor kept being triggered, alarm screaming. they guy was unlocking from key, but car was suspended, so could not have opened door. after like 30 seconds, again, same thing, alarm turned on. the guy had to actively unlock the car from my key every 20 seconds to avoid it screaming in the shop. MEGA FAIL
there must be a way to disable this permanently, I contacted the dealer and asked for instructions, I find it completely stupid as design and I don't see who could benefit from it, while for sure I can see numerous people being annoyed by it.




Managing your herd is hard enough. You don't need this aggravation.
What happens if your wife has a key and locks it from inside, instead of your locking it from outside?
When I'm away from the car and my wife is inside, I like the security of a locked car. But I know if I lock it from the outside and then she tries to get out, alarms will go off.
I think the interior motion sensors aren't active if it's locked from inside, and my wife can exit without alarms.
I wonder if it behaves differently for different bottle of years or different versions of MBUX.
Good luck. Hope it's something easy.
EDIT: I just went back and read your detailed scenarios.
I think it's possible that you have a competing setting in Mercedes me.
There's a new version of the app that came out quite recently, and I'm still struggling with valet protection. And perimeter alerts.

Logically…there wouldn’t seem to be a reason to make the alarm any different in Belgium/EU than in the US.

In the aftermarket coding scene, I believe this is called "alarm auto-on". It appears to be a feature, god knows why, but it's far from the only idiosyncrasy on the GLE...
The dealer looked into deactivating it, but couldn't. All they could do was deactivate the whole alarm module, I said yes please, but then I heard back they weren't allowed to from Mercedes BE.
The easiest way to "get around" the issue while fuelling up, is to leave your key in the car, and turn the ignition on. Then the alarm won't auto-arm.
For me the biggest issue remains the tailgate setting off the alarm, even with the key in my pocket. At the moment I've resorted to always opening the tailgate from the key (long press on the tailgate button) when the car is unlocked but the alarm is armed. Then it actually bothers with an unlock event and disarms the alarm.
I'm starting to wonder if we need to start writing strongly worded letters to Mercedes BE about this, because it's infuriating.

The interior motion sensor is on when the car is locked, because recently I left the window open in the garage and when I reached inside, the alarm went off. The car was locked then, however.
When your alarm arms itself, does the car lock also? Or is it just the alarm?
I've had the car lock itself when I was nearby with the key. It happens when the door handles are very dirty, sometimes it registers that as a touch.

I think it would be worth verifying, because your situation is baffling.

Your car appears to behave as if it is always locked, continuously rearming the alarm—this applies to all scenarios you mentioned.
Could you or someone else experiencing this problem take a few screenshots from the Mercedes Me app? Specifically, the "Vehicle Status" and "Vehicle Alarm" pages would be helpful to see when your alarm is armed inappropriately.

Did they verify that the app settings don't compete with the car settings?
Or, why post on the forum if you don't want suggestions?




I cannot replicate this behavior either with the key inside or without it. If you open driver/passenger doors using KEYLESS-GO the alarm won't rearm and the doors won't close.
My car was parked/closed for 18 hours, not sure if it's enough for it to enter "sleep" mode. I came to the trunk and opened it by pushing on the release button with my keys on me. It opened fine without any noises produced. Once it happened, I could see that it did not disable the alarm and kept the doors closed. I waved my hand in the trunk areas for a while but couldn't trigger the alarm, which is likely the way it was designed. Then, when I clicked "Open/Close" button on the trunk door, it came down and the car produced a "confirmation" beep, indicating that was closed (I have close confirmation sound turned on). So, it worked as it should have.
My car was at the dealership and they moved / open / closed it like 5 times while changing the tiers and washing it, no alarm was triggered.
It's all of the same nature. It looks like your car thinks that it's ALWAYS closed and keep re-arming the alarm, it applies to #1 and #2 as well.
Can you or somebody else with this problem take a couple of screenshots from Mercedes Me app showing "Vehicle Status" and "Vehicle Alarm" pages when your alarm gets armed when it shouldn't?
It may help troubleshooting, and it may give more information for a technician to assist in troubleshooting.
That's what forums are for!
There is no difference in app settings vs car settings. It wouldn't affect any of the behaviour anyway. The alarm simply auto-arms in some markets, even without locking. Yes, it's annoying, and I too consider it a defect (especially the tailgate issue), but apparently MB does not.

I guess that means that you can't override the car with the app.
I can.
Need to get on with getting Xentry/Vediamo running so I can code out all this crap, hopefully.
But just to be sure, I just sent an e-mail to MB BE, detailing the issues I'm having (both auto-lock and alarm going off when opening the tailgate). We'll see what they say.




Everything points to a bug, not a dastardly scheme from Mercedes.
No Guard 360 (as far as I know), and definitely no aftermarket alarm. Just the stock system (that I didn't even order, it suddenly "became standard").
I know, and it's strange. Hence why I've asked the dealership about it multiple times.
Might be a European-spec thing then?
It's very simple. Have the key in your pocket, get out with someone still in the car. After 30 seconds or so, the indicator lamp on the dash will start blinking, this means the alarm is primed (lock button on the key, or the door handles were never touched). Passenger now tries to get out or moves too much, alarm goes off.
