Ses light on-I'm an amateur mechanic and have been able to fix everything so far without going to the stealership-any help with troubleshooting/fixing would be greatly appreciated.Love the car and this forum!

Like the OP, I've been an amateur mechanic as well (over 50 years of it), have vowed never to go to a dealer/stealer if I can avoid it (a dealer charged my wife over $500 just to recharge her Freon in her Fiero (in 2002), while I was out-of-town; and damaged other components doing so), and I have a
growing? list of codes I'm trying to fix.
https://xoutpost.com/bmw-sav-forums/...-codes-me.html
CODES encountered so far:
P0171 - fuel system too lean-bank 1
P0174 - fuel system too lean-bank 2
P0313 - misfire detected with low fuel
P0365 - camshaft Position Sensor 'B' Circuit Bank 1
P0369 - camshaft Position Sensor 'B' Circuit Intermittent Bank 1
P0505 - idle control system, idle speed not plausible
P0171 &
P0174 keep popping back up (4 times), even after the DISA was upgraded with the GAS kit
https://germanautosolutions.com/prod...sa-repair-kit/, and the intake smoke-tested for 20 minutes.
P0313 has appeared 3x, even after the same services done above. P0505 2x, after the same tests. I rattled the IAC, but didn't clean it, as I was out of carb cleaner.
P0365 &
P0369 haven't come back after I relaced the exhaust cam position sensor.
Since I used the parts cannon twice already, I guess that I should try a new IAC and fuel filter (or test my fuel pressure first?).
There have been no starting, driveability or idling problems whatsoever; the X5 idles smoothly in neutral, and in drive as well.
If I need to test fuel pressure, then what thread size is the Schrader fitting on the rail? There seems to be a question about which ones work, and ones that don't. And I guess I'll replace the rubber boots as well, even though I couldn't find any leaks.
