I went to BMW of Valencia today for a software-retrofit on my 335i coupe to activate the alarm and they did a complete software update.... I asked specifically about the 29.2 and told them i didn't want any negative effects. if thats what i was getting i didnt want it.
I was told that the latest version v31.1 is good
. i'm a truster, so i went for it. i bought my car at the beginning of August and
my guess i was post v.29.2 but pre anything near v.31.1..... as my car drives differently now after the update.
feels to me like there is more low end power and with a smoother delivery. I am happy. tho i have not "nailed it yet". Hope i wasnt fooled by my own wishful thinking.
