BMW G20 330i - Traffic fuel consumption

[nattubed 0]

Hello guys, I recently purchased a BMW G20 330i 2019 M Sport, and I've noticed that my fuel consumption in city traffic ranges from 15-20l/100km,  with no hard acceleration(regular driving)  and in comfort mode. I've seen reports of others achieving 8-10l/100km in similar conditions, so I'm a bit concerned.

I've checked for updates, and the last software update was in 2021. Could this potentially be a software issue, or should I be looking into other factors? I want to ensure that everything is running optimally with my vehicle, so any advice or insights would be greatly appreciated. Thanks in advance

Doesn't sound right at all, my 2008 135i modded with 419wkw (double factory power) averages 12-13L/100km in city traffic. 

You might want to get it checked at the dealer or euro specialist.

I can’t think of anything in a software update that would affect your fuel consumption dramatically, so unlikely to be that.

Does sound a bit on the high side, so would be worth getting it checked out so it doesn’t lead to bigger issues later on.

Do you know if the car has been re-mapped, tuned or programmed? Some of the Interweb specials can do funny things.

Hello,, please share more information

how many Miles done? your maintenance history would be helpful ~

Rattle Noise: "Have you noticed any rattle noise at low RPMs that might be coming from the turbo, specifically the wastegate? A malfunctioning wastegate can lead to inefficiencies and should be checked to ensure it’s operating correctly."

Injector Maintenance: "Have you ever had the injectors cleaned? Faulty or dirty injectors can significantly affect fuel efficiency."

Spark Plug Condition: "When were the spark plugs last replaced? Worn spark plugs can cause inefficient combustion and increased fuel consumption."
