need some advice on Throttle lag and clunky gear change issues.
when the car is cold there is a lot of throttle lag and clunky gear changes (up shift and also down shift)
when the car is warm the throttle response is better but when I come to a full stop at a red and then get back on the accelerator it jerks into gear.
and this is all happening in Comfort mode...
Is this a transmission issue ? or a software update issue ?
and its a 2010 E63
thanks guys.

Its like the transmission/clutch is not engaging right away and when at a full stop it seems to go into neutral and then hard shifts back into gear once you accelerate.
not sure if its tranny or software related...

I've owned the car for 4 years. It has always had some throttle lag on a cold start, but recently has gotten noticeably worse.

or... bad valve body
