Update: I knew I potentially had an issue as I tore the MAP sensor o ring when I tried to install it in my new aluminum charge pipe last week. The only o ring I could find locally was a little small. I had the first opportunity to really get on it Friday night and shortly thereafter went into limp mode. I had the new correct sized o ring in hand and replaced it Saturday morning.
Initially I had some issues, then realized I had not plugged the MAP sensor back in. I had to remove the charge pipe to change the o ring. Reinstalled it and cleared all the codes and now my SES light is off!
This started with:
29F4 catless downpipes detected
29F5 same
2C7B Lambda propel behind catalytic converter 2, signal
2DED Power management, standby current control
The 2 catless codes are still there but are not throwing an SES light. Not sure how this worked out, maybe it was all the o ring leaking boost that caused other issues. I’ll keep an eye on it.
