2021 BMW 330i Fuel Range + Gauge After Coding

deepanpatel90 · 07-18-2023, 05:44 PM

Hi everyone. I purchased a 2021 330i in early June. I have coded in a few things using Bimmercode. One of those things was the M Sport instrument cluster. I noticed that after coding in the M sport instrument cluster the range on the fuel tank dropped as well as the fuel gauge level itself. My range went from 310 miles to mid 270's. Is this normal? I don't know what my exact fuel level is now. I also tried the other 6 options (Alpina, M sport, 160, etc....) the fuel range was a different number each time. This was all back in mid June, but I have just now gotten around to posting about it. Thanks!

Thanks. I just hate not knowing how much fuel I have in the car. Hopefully it corrects itself. I’ve done two tank refills since coding and I’m never sure if I’ve over filled the car or if the car really has more gas in the tank than being displayed on the instrument cluster.
