The vehicle can be coded to allow the full use of the tank. The dealer won't do it, but it's not all that hard to do yourself. You do need to buy an adapter that plugs into the OBD-II port (which one depends on the s/w you use to program the car), but they are not expensive. If you have an Apple product, the Bimmercode app can do it. If not, you'd need to download a bunch of software and work your way through configuring it and figuring out the programming. Some people offer remote programming.cancad said:Where are you? What is the range displayed when the tank is full?
I am in Canada and was told we have American version, in which the tank is limited to 1.9 gal. I am trying to figure it out but don't know how.
2014-2016 North American i3 REx's have their fuel tank capacity software-limited to ~1.9 gal. This software limit can be eliminated by coding.cancad said:I am in Canada and was told we have American version, in which the tank is limited to 1.9 gal. I am trying to figure it out but don't know how.
This makes a lot of sense because for MY 2017 and later the battery capacity has been increased so that even with 2.4 gal the fuel range will not exceed the electric range. Full use of 2.4 gal tank is what I thought it would be.alohart said:2014-2016 North American i3 REx's have their fuel tank capacity software-limited to ~1.9 gal.

2017 North American and all other market i3 REx's allow full use of the physical fuel tank capacity, so no coding is needed to be able to use the full fuel tank capacity.
Starting with 2017 models, no REx models anywhere in the world had software-limited fuel capacity. So there was no possibility for you to increase your i3’s fuel capacity via coding.cancad said:Today I had a chance to code my 2018 i3. Under “Increase fuel capacity” the original parameter was “unknown value”. I hit “active” and then “code”. After coding completed the fuel bar on the cluster has no change. In the app “unknown value” is gone, and “active” is the only option. These may all mean the fuel tank was always in its full capacity.
