Hi all

My M340i xDrive (European model - Denmark) had good deep burbles on downshifts when I got it back in October 2019, however in Europe the M340i never had the pops on upshift like in North America.

But since the latest software upgrade in December 2019, the burbles have almost disappeared. My trusted BMW dealership tells me, that it is due to EU regulations to lower emissions and noise!? You also see the same thing happening to the good sounding Audi RS3 which is now almost quite as a bird. Also the new AMGs are suffering badly under the new regulations.

Still love my M340i … but will consider getting it “ECU mapped” for more sound and horsepower when the warranty runs out 😊
