Fuel warning at 20% remaining
Hi all, just had my 2024 M2 go into a sort of limp mode due to low fuel. I was turning right at an intersection from a stop, and all of a sudden the throttle response went to crap and the car slowed down, and I saw a fuel warning saying "Full engine power not available, please refuel". But I was at 20 percent fuel remaining, and driving very slowly (car not warm, still in break in too).
Luckily I hadn't pulled out in a tight gap, it was quite a jarring loss of power. Gas station was right there, chucked in a couple gallons and warning disappeared. I have searched this and only found reports of people getting this falsely on track, presumably due to fuel sloshing around. But has anyone else seen this during normal in-town driving? Going to talk to the dealer too of course. I could see this being dangerous if I was counting on the power to pull out in traffic. |

Does the G87 have a gas light? Are we not allowed to use the car until the gas light comes on, then find our nearest gas station, like every other car?

I have taken it down to 15 miles with no power issues (just warning into fuel reserve).
When I filled it up, it took 12.8 gallons (tank is a 13.7 gal tank). |

I got the reduced power alert in my wife's X3MC when it was down to 17 mi on the range remaining display which would be about 1 gallon of fuel remaining. |

With the range at 35km I got the reduced power warning, it needed just under 48 litres to fill the tank, so about 4 litres remaining.
I did manage to drive 630km (391 miles) on the tank to that point though, for a fuel consumption of 7.54 l/100km (31.2 US mpg / 37.5 mpg) |

My average efficiency in August is 23mpg, can't imagine it was spooked about range. I'm going to run it low again and see if I can reproduce, I should have taken a picture of the warning next to my fuel gauge and MyBMW app to show the dealership. |

think people are mixing up the two alerts, first is the low fuel alert which for me goes off at 50 miles of range remaining. second is the reduced power alert which again for me goes off around 10 miles of range left.

Ah, I have never got that low so I didn't know there was a second one.
So is there a way to change the low fuel alert? I think that the alert going off at 1/4 of a tank is a bit too high for me |

My initial warning is at 50 miles left. Another pops at 30. But the power cut doesn't happen until about 12 miles left. When that was identified just made sure to refill by 2nd warning at the latest going forward.

I’d make some changes on the mileage/power alerts if someone points me in the proper location. |

Same. I have been at well below 20% multiple times without receiving that warning. It wasn’t until I was on near fumes based on the read out that I got the notice of change in power.

i think you need bimmercode to change. from what i understand there is no factory settings that can be adjusted. i am sure the lawyers prevented that...

I get the one at 50, and then at 30 a "hey, dumbest, you are running low" but as I haven't gone lower than 15 miles, no limp mode. |

Found out the Supra had the same gas tank - and read about fuel starvation incidents on track when the fuel was getting low. i made it a rule to keep the tank at least 25% full (approx 12 L). I noticed the M2 has a similar gas tank to the supra. I also find the fuel indicator on the M2 iffy, so i monitor fuel via Bimmerlink. That said, experiencing that fuel cut out from making a right turn seems a little much. Again, i don't quite trust the fuel percentage. Last edited by motorknut; 08-13-2024 at 01:36 PM.. |

It's possible I saw the ability to change the alerts in Bimmercode.

I’m anal with new cars, actually and any piece of technology-phones, tablets, televisions, etc. I push every button, select every option, change all the settings basically to learn and secondarily to see if I can escape the mistakes without crying “uncle”. I’m not a bimmercoder so I can’t fu** that up to any extent. |
