bought a 2019 i3 rex. do i need to code gas tank?

Mon Oct 07, 2019 11:16 am

Or is for 2016 and below only?

I will code hold mode. But someone told me the bigger gas tank is only for 2016 below models. is that right?

Absolutely correct, you do not need to code the gas tank. You will notice when coding that the settings are already applied for your vehicle (which is what I found when I tried to code my 2018).

FWIW, the actual tank size is identical for all i3's...the amount you can use is controlled via software. A bit of history:
- To meet a CA requirement and get certain credits, the electric only range has to be larger than the engine augmented range. BMW chose to secure that credit. But, as the battery capacity got larger, that restriction in 'size' of the tank became a mute problem.

The logic with the coding is that the gas tank had to be dumbed down in operable size due to the percentage of miles vs the electric miles. To meet requirements, the gas range can't be even with the electric range nor even within close proximity. I forget the exact numbers but that's the logic. So since the newer models have significantly higher electric range, BMW doesn't have to lower the gas range to meet their requirements. The gas range is already low enough at the actual tank size. No need for them to dumb it down.

There are some codings you might enjoy:

  • ECO mode - moderates acceleration to extend EV range with little impact on driving.
  • tire temperature and pressure - something I use to see if a problem is developing.

I'm not sure "dumbed down" is quite the term I'd use when it was done to make one eligible for tax and utility incentives and perhaps other benefits. It wouldn't have helped me specifically, but would have made the car more affordable for some folks.

But it's certainly better that the battery capacity has increased in 2017 to where no tricks are needed to get your tax credit or HOV sticker or whatever.

As far as the description, each to their own. The point is that software purposely doesn't recognize the full physical capacity of the tank.
