Hold State of Charge issue & Issue with gas flap

Fri Feb 05, 2021 6:49 am

I have a 2017 REX and had no issues coding my car. I made some updates and now my state of charge will not work? Used Bimmercode. So weird. I also coded spot #1 so can hit the REX when I went below 70%.

Second issue is the gas flap. Anyone else have an issue with it sticking? I get an error message and need to manually pull that green tab under the hood. As a result I get a check engine light and need to reset with my Bimmercode app.

What exactly do you mean when you say your State of Charge won't work??

The gas flap issue shows up when the fuel tank pressure sensor fails or is out of calibration - you should be seeing it stall during the depressurization cycle at 25% - 50% in the dash display . Known issue to the point BMW has extended the warranty on it to 10 years, 120,000 miles. ... 9-9999.pdf
