Help Identifying This Sound 228XI
Featured on BIMMERPOST.com For some I know this will be hard to believe (since I've owned the car since 3/13) but I just drove using Sport + mode and heard a strange sound. I had to pull out on a street here in NH, the speed limit is 55 and had lots of traffic. I switched the car into Sport + and booted it The sound came when the engine was revving down to shift gears, I'm assuming it is the excess pressure of the turbo being dumped. I never heard this sound before and wanted to check with those who know, it is a cool sound though Thanks ASM |
