Low fuel = reduced power

translux · 04-01-2021, 02:59 PM

Low fuel indicator came on followed by a reduced power notification.
Power was severely limited with something like a 3500 rpm cutoff.
I didn’t pay attention if the reduced power came on right away or increased after I drove a few miles with the light on.
Filled up and message popped up with something like fuel recalculated.
Car is now operating as expected.
Never seen this before, hopefully doesn’t happen as soon as the low fuel warning comes on. This is usually when someone wants to play

Interesting, thanks for relaying. I am never a fan of seeing that light, always prefer to fill up at about 1/4 tank. Low fuel light makes me anxious..

spacecowboy85 · 04-01-2021, 06:40 PM

Weird hasn’t happened to me yet and I purposely ran it low once to see what the actual range is after low fuel warning, I went down to 10 miles left till empty got warnings never power reduced

C'mon that's soft... it's how many miles you go after it reads 0 that counts

umm i just got back from filling up when remaining range was reading 50km ... nothing of the sort re: power limit came up

translux · 04-02-2021, 12:31 AM

Given my poor history with 1st year BMW’s this has me little spooked.
Hopefully it was a fluke.
500 miles to go until break in service. I’ll have them check the logs to see what happened.

Just noticed you’re local to me, when did you get yours? I’ve to a couple of cars and coffees looking for another G80 to park next to. Lol

dms-01 · 04-02-2021, 07:39 AM

Happened to me when I test drove one when they first arrived at dealers. Tank was Low and had like 10 miles or so.

I used to get the low warning right around 1/4 tank in my F80, maybe a little more. Glad the F92 has a larger tank.

I’m in the south suburbs. I need to get out of the house so would definitely meet up at a c&c really anywhere. Please shoot me a pm when one is coming up. Hopefully I’ll be past break in

Hearing that I’m not the only one to experience this makes me feel better. Thanks for commenting.

translux · 04-07-2021, 11:52 PM

Definitely a real thing for me at least.
At around 20 miles to go got reduced power message with reduced 4K redline.
An attempt to avoid someone running lean during spirited driving?

freshxdough · 04-08-2021, 02:08 PM

Seems like a smart idea honestly. You shouldn't really be pushing the car with less than ~30 or so miles left of fuel anyways.

Yep, agreed.

Especially on my M2C with it's lousy 13.7 gallon tank.

I’ve experienced this twice now

dms-01 · 04-14-2021, 06:27 PM

Did OP really say he was going to have the dealer check the logs over this? It's by design man what are they supposed to check?

hova00 · 04-14-2021, 06:44 PM

Happened to me the other day. Tank was extremely low.

kingmonkeyjr · 04-15-2021, 12:02 AM

It caps the car at 4,000rpm

King

Well I’ve never seen this before from any car I owned.
At 1st service writer said it was not normal, then called me back and said it is.
All good just an interesting feature.
Given how this thing goes through gas at full send it’s probably a great thing.
Lean is bad
