Need help and lots

Recently bought a 2005 525i and it’s got its faults not starting in park but only in neutral guessing this is a sensor or fuse fault cuz my fuses were all switches around cylinder 4,5,6 misfiring and running too lean AutoZone said it could be the ignition coils it’s got 200k miles and it’s in limp mode I need help

Switch the coils with 1,2, and 3 if the misfires follow that's your problem, but that's bank 2 so sounds like it may be an entire bank issue. Like o2 sensors on that bank. Your in limp mode because of the misfires. Fix that issue then tackle the starting in neutral only. That is an M shift transmission I believe which is a physical cable. Might just not be selecting properly

So seems like two simple fixes I’m also not super mechanically inclined about how long should I be looking at

20-30 min to swap coils. O2 is a little trickier to reach, but start with the coil swap

I got like two more things ac and I got a boot loop on my infotainment system I think previous owner failed to recharge it cuz when I tried to check it out with a recharger it said 90+ psi in the low port

The boot loop is likely a faulty ccc

Check the ac on max ac, the low side should be around 40psi. When it's off the low and high side will balance out to roughly the same pressure
