I posted on N54 forums but didn’t get much help. I’m running 335is 2011 with jb4 mobile ok current firmware with DCIs that’s pretty it. No codes in the jb4 app so I bought a k dcan cable and started learning my way around inpa and ncs expert. My version of inpa is half English so that makes things a bit complicated. But I’m trying to rule out simple things before I immediately orders a abs until. DSC light DBC light abs and take off assist all popped up out of nowhere.

Here’s some weird things I noticed first gear will not rev past 3500 no matter what and is way below target boost. Secondly radio speakers occasionally just quit no sound at all. Garage door will not open sometimes with home link, some times comfort access will not detect the key at all. I’m not sure how many of you have the jb4 mobile app but if I display gps speed vs mph mph is way off 20 plus more than what I’m actually going? Any input?
