Alright guys help me out here. Was doing a pull a few days ago and the car threw itself into limp mode with a service light. No codes came up so I reset the service light, but now the car still seems to be in limp mode. I still hear the turbos spooling but when I let off the blow off sounds like a huff instead of the usual pfft. Scanned the car again, no codes came up so I did a deep scan and these are what came up. I was thinking it was going to be a boost leak but I'm not getting any codes for boost. Car drives fine otherwise just feels like an absolute slug.

While you are waiting for some troubleshooting ideas..... get it on a battery charger and let it get to full 100%

Umm...have you popped open your hood yet to visually inspect the engine compartment? You never know...:)

Make sure everything is tight and secure in your engine bay any vacuum lines or any connections that may have came loose and check your battery terminals make sure there tight and have no corrosion

I took a quick glance earlier and from what I see all the vacuum lines are still connected as well as the CP. Don't have much time to look at it atm
