Rough idle jerking at stop

I got my 2014 vw passat 2.5l February 2019 the
second day I had it it went below freezing and the
car was completely dead so I did some research
and I replaced the map sensor cleaned the throttle
body replaced the secondary air sensor replaced
the pcv diaphram twice got new spark plugs and
still to this day September 2020 it stall or had a
rough idle after driving for a while it jerked at a
stop light. It put a code p0106 a few times but I
really have no idea what to do I might have to take
it to the dealership and pay for the labor but if
anyone can help that would be awesome
