I have a 2011 528i with over 200k miles. When i first bought the car it would randomly go into neutral while driving. This would happen maybe a few times a week, moreso on longer drives. Since its gotten colder outside, the issue happens much more frequently to the point where the car is barely driveable and now it stalls out completely sometimes when going into neutral. Everytime the car goes into neutral, the Oil Temp Gauge(far right) will jump up to a normal reading for a second(otherwise stays cold for the first 20 mins) and the check engine light will flash. On the second or third time of going into neutral, DSC malfunction will appear and remain on for the rest of the trip.

I have replaced the EGS harness, Mechatronic sealing sleeve and adapter and did a fluid change to no avail. Car has mutiple DSC, EGS, Engine codes which i will attach screenshots of. I was told to have the car diagnosed with ISTA and was told the C and D Transmission Solenoids are dropping out which causes the car to go into neutral. Ive run the codes on the car several times and never saw anything about solenoids. My question is are ALL these codes related to the same problem?? Is it a computer or wiring issue?? What am I missing?? Should i have the car thoroughly diagnosed by someone else??
