My build date (based on the label on the front drivers “A”pillar) is 5/17.
My car with a build date of 04/17 has a 4G label on the Telematics Control Unit. Yours should as well, but you would have to pop up the rear seat and remove some brackets to get to it.
When the BMW online shows up in the corner of your I drive screen, does it indicate 3G or 4G..? Of course 4G requires a 4G SIM card AFAIK….
Mine shows 3G, but I don't think that "icon" is generated by the Telematics box. I'm pretty sure it is generated by that version of the iDrive software, so it is rather misleading.
Related Anecdote: Sometime last year I read a post (where I do not recall) of someone with either a 2015 or 2016 model that had a 3G Telematics Control Unit failure under warranty. It was replaced at no charge but BMW did not have any 3G units, so they put in a 4G unit and programmed it. The owner noted that if he paid retail for the repair, it would have been about $1500 USD. He also noted that despite the new 4G box, the screen still displayed "3G".
The real telling factor is that owners with 2014-2016 models that have 3G are not allowed to renew their Connected Services when they expire because BMW can't guarantee service past Feb 2022. If I go to the Connected Drive portal either via the app or via the website and log in, I am now within 30 days of Expiration, but allowed to Renew Services for $50 for a year for basic remote access. They also are now offering me Basic Remote Services PLUS RealTime Traffic Info for $90/year which was not an option a few months ago. These options are not available if you have a 3G Telematics unit.
BMW did offer to extend full Connected Services to ALL model years affected by the 3G sunset. This meant if your services expired and you could not renew, they allowed you to click a few links and Services would be restored for no charge for less than a year, until Feb 2022 when they would shut off.
But again, this does not apply to the 2017 model year based on everything I (and others) have found in the past few months.
