Car is 100% stock. 2022 G80 6 MT. No tune, no aftermarket anything. Original owner. Car is not abused. I use 93 octane whenever I can get it. Car is not tracked. 26,000 miles. Driving at normal highway speeds all of a sudden I see a check engine light. Car is still driving normal.

Car is showing 1/2 tank of fuel. I fill up the car and the guage does not move. I drive the car the next day and fuel goes to 0. Watching the guage drop to 0 was a little nerve racking. I was not sure if the fuel pump would shut off even though the car was driven 70 miles from another refuel I did. I did get a reduced power warning.

Way before this I would get this feeling that the car would surge under a light press on gas pedal at HWY speeds. It’s like the sensation of a stuck throttle on a motorcycle for a split second.

I have an appointment for this Thursday.

When it’s resolved I’ll update the post.

UPDATED:

A damn mouse chewed a few wires that connects to the sensor that feeds information for the float. (Now my garage has a generous amount of mouse repellent pellets around garge. Also some crushed mice poison.) Garage smells like I have a big “mint” air freshener. Anyway it’s described as wiring harness damage. A few wires apparently touched and shorted every electrical component associated with the fuel system. The tech did a fantastic job with the video and describing the steps he was taking to resolve. (Tried to tip the tech but he was out for lunch when I picked up the car.) Also did a video of undercarriage, tires, brakes etc. the M3 got a clean bill of health for that part.

Repair cost: $1,463.67 ($20 in parts rest labor) for the repair obviously not covered by manufacturer warranty. It was covered by Geico under comprehensive coverage; “animal damage”!

Geico went to the dealership paid them direct and I paid my deductible.

While car was in for repair they did a covered no additional charge scheduled service. Oil and filter, air filter, spark plugs and software update.

Car is running butter smooth glad to have it back!

I wouldn’t drive it anymore until it’s looked at. Without a scan, you don’t know what exactly it is and driving it if it’s got a fuel supply issue isn’t going to be good with the engine, especially since you got an additional warning for reduced power. Stop driving it.

Agreed.

Parked it last night.

I have another car I use as my daily driver.

Float sensor went bad and the reduced power is because his car thinks he’s out of gas. It’s not a risk to drive as long as he knows he has fuel. The car would alert or shut off if there was low fuel pressure (high or low side).

Good luck. Pls keep us posted

Maybe so but without a scan to be sure, I wouldn’t risk it. Why I think one should always have scan software if they’re an enthusiast… helps when you work on them too and need one.
