I've owned my new (used) 2011 BMW 328i xDrive w/Steptronic Automatic Transmission for almost two months and I must say that I've never had an issue with harsh engine braking. Nor have I experienced any high-pitched sounds. Try disabling the courtesy lights (via iDrive under the lighting menu) which activate for about 30 seconds when you unlock the car. Maybe you have a defective electrical component in the lighting circuit that is causing the sound. Or, it could be the fuel pump priming (the fuel pump runs for a few seconds when you unlock the car so the fuel rail is up to pressure). Not sure what to tell you about the transmission. You can try pushing the shift lever into N (neutral) just as you let your foot off the throttle. That way the transmission will be disengaged as you coast to a stop. I owned a 2004 BMW 325xi prior to this car and I can say that I absolutely LOVE my 328i xDrive. Love the fit and finish, love the styling, love the handling, and absolutely love driving it. I look forward to my morning/evening commute every single day!Report it
your high pitched sound is a defect. Run-flat tires are harder than normal tires and if you have narrow tires, they'll run harsher over bumps no matter what size. When you need new tires, get the regular tires and your ride will improve, plus theyre cheaper. Engine braking is good for me. I appreciate the feature. Sounds like 2 of 3 of your issues could have can be resolved. Getting car sick from engine braking is unfortunate!Report it
