battery drained due to OBD port

My turn to chime in
I can personally verify that MY 2017 F-Types are not immune to this ongoing cluster! Yesterday, I returned from the dealer to get a simple PA State Inspection/Emissions, and sure enough, my hazard and door unlock buttons remained illuminated well after locking the car in my garage. Luckily, I contacted our in-house expert Unhingd and he walked me through the process of rebooting the battery--I'm a slow learner, right Unhingd LOL! After the reboot, the hazard and door unlock buttons went off a couple of minutes after locking the car. Thanks Unhingd!
Apparently, the dealer needed to access the OBDII for the emissions. B/c I was on top of this issue, I knew right away that the car wasn't going to sleep b/c they accessed the OBDII port. I too am amazed that JLR has not been able to successfully address this issue! My car's build date as per the driver's door jam notes 11/16 (although my invoice from yesterday notes a production date of 12/5/16???). Perhaps this "Enhancement Letter" which has worked for Unhingd may do the trick, but I find it hard to believe my car would not have been updated given its relatively new build date???

So this is the BS I get from my dealer after I complained no one got back to me yesterday as a courtesy:
I talked with both of my shop foremen and they have not heard of an instance where plugging something into the obd II port would wreck havoc on the electrical system. The "Jaguar vehicle enhancement program" letter you received does not address such concerns you might be having. Most new Jaguar vehicles have received this letter and we typically perform software updates to certain modules if there are updates available. There is most likely another issue.

Not to sound like a moron myself, but how would this letter help my situation?
God, first I come across your replaced differential, and now this. I certainly hope I didn't make a mistake coming back!! j/k, so far so good, but....

In my case, why didn't my car go to sleep when nothing was plugged in?
Like I said, I have to pick my battles. This was an easy fix for me to do myself, and hopefully it will only have to be done once a year following my annual service. Although, I will be sure to test and see if the car goes to sleep before leaving the dealership next time!

So even with the letter in hand, they did nothing to your car?

with regards to the obd port issue I definitely know mine will not go to sleep after anything is plugged into the port. Discovered after borrowing friends diagnostic kit.
luckily I found this thread so performed the reset
What I am curious about though and I haven't found an answer for as yet. If a wifi or Bluetooth diagnostic chip is plugged into the port and the battery module is then reset with the chip still plugged into the port will the it still go to sleep or will it only fully reset when there is nothing plugged into the port
Anyone know

Just adding to the list... I frequently plug an OBD device, a couple times a week, with key on engine off, and have not encountered this problem. 15 R coupe. I do not leave it plugged in all the time. I use it and then unplug it.
Before unplugging I hit "end communications" on the tool. Maybe that's relavant?

Ok, so here's what I did and it seemed to "fix" the problem without disconnecting the battery:
First what happened: Checked the car with the OBD (a handheld device with screen), after finished I selected disconnect on screen to end the communication with the car like I always do, then unplugged as usual and turned off ignition. Got out and closed the door. It seemed the car was more lit up than usual to me. Waited a while and the hazard light button never turned off.
I don't know what parts of this are relevant or not relevant, but here's what I did: Opened hood, connected 10 amp charger to jump points. After a few minutes he charger stopped and went into maintain mode, since battery was topped up. With charger still connected, I turned on ignition (charger now went into charge mode due to increased load as expected), I pressed OK on steering wheel for the couple messages (door open, etc), I waited 30 seconds or so, then turned off ignition. Exited car, closed door, didn't lock it. Left car alone for less than 10 minutes (I had set a timer), and the hazard button light was off. Good. Disconnected charger, closed hood, locked car. All seems OK. I'll connected the charger tomorrow and see if it drained based on whether it charges for a while. Like I said I have no idea what if any of this did anything or if I merely got lucky....

I think your right, not sure what it is but yesterday I was washing the car had all doors and trunk and hood open and at one point switched ignition on without starting the engine to raise the spoiler to clean underneath.
This morning infotainment defaulted to DAB radio on startup I have USB stick set as source so something reset.
so maybe is ignition on without starting engine with or without hood open

Let me chime in here too. I scanned the CEL I got with an Acutron scanner. Yesterday morning and this morning (CEL was Saturday), I got "Battery Low, Please start ignition" warning when I first go to start the car. Forgot about this thread, but remembered vaguely reading about battery drains here. Going to disconnect the battery now. Forums FTW.
