Second post about my CPO 2016 328i - just got it a month ago - preface: BMW ran diagnostics on the automatic transmission and state there is no issue according to their testing. However, I notice that when i accelerate from a stop, and when I drive under 20 mph or so, sometimes there is a jolt/snap into gear. it's not so much so that the car lurches, but it is also not smooth like when the car shifts when I'm going over 30 mph or so. Does anyone have any thoughts on this? Is it the way I'm driving? BMW reset the adaptive transmission settings or whatever, which didn't make much difference.
There are throttle position/speed/RPM combos that will cause a shift that seems harshly out of character. Usually very slight acceleration and very light throttle application at a low speed. Like when driving in a residential area where you're just putzing along.
Hey thanks for the reply. Are you suggesting this is normal behavior?
It's possible. Do you usually only notice it during the conditions I described? If it accelerates normally when you're actually accelerating, say from a traffic light, then it's probably nothing to worry about. Even more so if it only happens with a cold engine. A cold engine will exacerbate the dramatic shifting at "low speed, light throttle, slow speed".
Ask the dealer to install a data logger to monitor the usual suspects for your problem. This is better than taking it to the shop, as it probably never happens in the shop.
If they won't do it, as to speak with the BMW Zone rep.
A dealer will install a data logger. If they say no, then ask to speak with the BMW zone rep. Remember, if you never ask, you'll never get a date.
This is exactly what I was searching for.
I have a similar issue, at trivial speeds, like walking, with the barest touch on the throttle I get a jolting/knocking when I want the car to ease forward. More prevalent when up a slight hill. If I give it any proper push then the car pulls away nicely.
Did you make any progress Twoseconds?
