hey guys - have a 2014 F31 328d xdrive m sport w/adaptive suspension and auto trans.

for the past few days, regardless of what mode i'm in or how easy or aggressive i drive the car, it's doing this hesitation / slight jerk thing before shifting gears. it's almost like it's slipping but not.

if i'm in traffic and going around 15km/h or 10mph, it does the same thing repeatedly. almost like it can't decide whether or not it wants to shift.

any ideas?

Mine does this or something similar. I will accelerate slightly and watch the rpm drop and a fraction of s second after the rpms drop on the dash I feel a slight jolt/kick. Does it from 1-2/ 2-3 after that it's smooth as glass and I can't even feel it shifting.

how many k are your at?
might be a sign to change Tranny oil and filter.
just a thought.

This was happening to me as well on my 335. I had around 57K on the ODO and swapped the trans oil and pan. I purchased the kit from FCP Euro. Transmission is silky smooth now in all modes. Obviously Sport and Sport+ are going to be a bit less smooth, bit it's by design. I'd get your transmission oil changed (NOT FLUSHED) and go from there.

100,000kms / 60,000 miles - feels early

Thanks! I'll give this a shot.

Do you have a procedure on how to do this?

I took it to the dealer. This procedure is a bit involved and I wanted to make sure it was done correctly. Certainly it can be a DIY deal, but I didn't have all the proper tools or a lift to do it right.

My tranny does this only when cold, but the behavior is what you describe.

Not yet, had to go on a business trip so service got moved to this Thursday. Will let you know how she drives after!

My car is at the dealership because I felt this issue. Apparently they haven't been able to replicate this yet...

How did they come to that conclusion?

They test drove and then did some diagnostics and ran it in RWD only and it was smoooooth, car never had any codes, but apparently it's not the most uncommon issue with F30/1/2 x-drives... I did a quick search afterwards and there's quite a few similar experiences.

https://f30.bimmerpost.com/forums/sh....php?t=1407191 - this thread tracks a lot of other experiences and the guy found a correlation with staggered factory setups, which I have. What wheel setup are you running?

Thank you for the info. I have a square set up from the factory. Hasn't been changed and haven't wanted to change it for the risk of screwing up the Xdrive.
