CEL with JB4 (Account not linked yet)

def connections. you should also always do this with battery disconnected. If connected and the connection isn't lined up perfect, it can short across pins like what I am guessing and the computers on these BMWs are SUPER sensitive.

Okay I checked every single pin, they look fine. I guess now I just disconnect battery

This looks better now. The top list of codes you have are faults/shadow codes.

I am honestly surprised at how fast I took apart everything, checked all ports and put it all back on. Took only 30 min. Anways im gonna disconnect the battery now and reconnect yeah?

So I haven't disconnected battery yet, but CEL is gone, should I delete these codes?

I would have disconnected the battery before you adjusted any sensors and left it disconnected while you were adjusting it.

Yes.

Update, I disconnected battery and reset. No codes. No CEL.

Drive it to make sure

Drove it for about 20 min earlier and another 20 min just now. Still in the clear

The likely problem was that the car was 'awake' when you disconnected the wastegate and the TMAP in the chargepipe.

The car registered this as a problem, and doesn't clear those on their own. You should be good to go now.

Definitely check out the wastegate and MAP sensor connections. It looks like something(s) aren't quite right.
