CEL - P2097 Error

Mon Oct 11, 2021 5:05 am

I bought a month ago a 2015 BMW i3 with range extender. I bought it used from a Ford dealership that had the car checked out by BMW, which said everything is running properly. I went ahead and got a Veepeak OBDII and Bimmercode. I enabled the Range Extender HSOC and increased the tank size.

Every time, that I use the range extender the CEL pops on and throws me the error message P2097: Post Catalyst Fuel Trim System Too Rich Bank 1.

Any idea why it's doing this?

Thanks!
