OBD II
After having a flat battery 2x from the infamous OBD port II disconnect after the state inspections in years past, I asked the dealer today about when I took my 16R in for service as it's also due for the state inspection
He said they have an old bulletin which updates a module which should tackle the problem. I'm reticent about the software update because of the potential to dull the pops & crackles as I believe they're software controlled.
Are you familiar with this module update, if you've encountered this OBD disconnect issue on your car? If you've had it done, did it affect your exhaust sounds? I'm trying to judge if it's worth doing or not!

@Cheapo911 Don't know for sure, my 2 cents would be to let them know you experience the battery drain issue after state/emissions inspection, and are they are able to fix it. It may depend on how many F types your mechanic sees - my service manager said his level 4 tech was very aware of this issue. Asked what the bulletin/service number was, and apparently JLR has removed the bulletin notice - I wonder why, as it seems to be one of, if not the most, prevalent of its quirks.
I may well be wrong about the pops/crackles being software related/driven.. I would confirm with your service manager that the only software update they do is just this gateway module and instrument cluster.

Great to know @DJS and @winstonsalemncxk Peter - it was, shout out to the tech Jason Lanciki, service advisor Brandon Sisk and service manager Jack Thill for what seems to be a fix for this
