I bought a 2016 Rex in the middle of last November with 128k or so miles on it. Since then, it's done about 800 miles, and is granny charged about every ten days and the Rex tank filled up about once every 2-3 weeks. Absolutely over the moon with it, my first BMW.. in fact, the first time I've ever been in a BMW. I think mine is Tera spec, it's got the larger screen, leather upholstery, led door handles. It doesn't have acc or front parking sensors but it's so easy to manoeuvre. I've just recently fitted a PremiumRetrofit kit to get Android Auto on the big screen. As it involved taking the back seat out, there was strangely a load of glitter under there, a vacuuming job for another day. As the weather is starting to gently warm up, I've noticed the battery range estimates about 70-75 miles so it's been treated well before I bought it. The original owner was someone working at the Alphabet company for 3-4 years! I need to code a couple of things through OBDeleven like always start in Eco mode as it's primarily used for short commutes (I say short, about 5 miles in 50 minutes, Birmingham traffic is crazy). Love this car though. Starting it the first time for a test drive it was weird, with no noise at all. I only really hear the Rex when it's HSOC up a nearby hill.
The only thing I've found on it is the fuel filler flap doesn't open easily. I guess pressing the button in the drivers footwell should release the flap and it springs open like the EV flap? It does nothing and I have to fart about a bit getting my fingernail underneath to get it to release. I asked my local BMW dealership and they said they'd have to run a diagnostic on it. Is it a cheap/easy fix as I guess it might be a dud solenoid, or perhaps a not quite pushed in cable connection? Is it also a BMW UK recall item?
