Do you mean it's not opening? The tank is pressurized and it takes some amount of time to release the pressure before you can open the door. Someone else posted to hold the button down for a few seconds and you will see a message on the dash that when it's ok to open, or some such thing. Search this forum and you'll find it.

Just dropped mine off at the dealer this morning. Apparently if there is something up with the REX system, the fuel door will not open except by the emergency release under the hood.

The dealer called late this morning to say that the fuel pressure sensor was bad.

Good to know that I am not the only one. With 3 days to run to the end of my warranty, this happened to me yesterday after a prolonged use of the REx. Pressing the de-pressurisation button gives a Ready to Refuel at 25% message but the flap stays locked. Pulling the Frunk ‘emergency’ toggle releases the flap. The fuel cap then releases easily but no obvious release of pressure. I have it booked in for investigation: I will mention the possibility that it is the fuel sensor.

Yours wouldn't happen to be a 2015? If so, can I ask the month is was made? You can lookup the manufactured date here: http://bimmer.work/

Our 2015 (born in July) - (we didn't know at the time) had a Fuel Pressure sensor that was failing on a long road trip, where we had to rely on the REx. 9 out of 10 times, we had to do the manual pressure purge (green tab) to open the fuel tank...then in the middle of the trip, the REx drive train would not come on - luckily opening and closing the fuel door/opening the cap restarting the car a few times, eventually it came back online....after getting the fuel pressure sensor replaced, everything functioned as it should (open fuel door without issues, no REx drivetrain issues, etc)

I read somewhere that BMW started using a different/better? Fuel Pressure sensor sometime during late 2015 or early 2016....If yours is a late 2015 - if the rumor is true, then maybe they got around to putting the different/better Fuel Pressure sensor sometime in 2016....

My date of manufacturer was 6 March 2015. Is there an emerging trend here?

2014 I3 REX Electronaut edition. Bought from non-BMW dealer with two months of remaining BMW warranty. On my first drive and after using REX, fuel tank lid cover won't open. A Message about 25% appreared, and the nav screen saying to open the cover manually. Pulling on the green cord under the hood (next to the wiper fluid tank) released the cover. For every refuel, I had to release it manually. A BMW dealer is checking on it now.

My dealer has confirmed a faulty fuel sensor is the cause of my problem. New sensor arriving tomorrow.

Hello everyone. I have the same issue on my 2015. I haven’t put gas in it for maybe 18 months but now need to refresh the gas and open the cover to do my emission test and it hasn’t been opening! The dealerships in my area (Atlanta) have been pretty bad in terms of appoitnments and i need to open it manually. First time i pulled too hard and broke the green cable. Was able to find it but pulling is not helping me. Any tips? I used to love this car but have been frustrated lately and happy to be returning it in a couple of months:)
Thanks

Very common issue with mid 2015 or older i3 rex. Dealership replaced it in 3 days under warranty. And BMW sent a letter offering free extended warranty on it for additional 10 year/120 miles!!
