Redlined in 1st Gear, Now in Limp Mode

AAA guy said battery is fully charged and no issues there. I will have it towed to the dealer tomorrow. Thanks!

This escalated quickly. Buy an OBD2 scanner if you want us to help. If it goes to the dealer you can deny modding it, but they’ll know it was over normal boost levels.

Get an OBDII scanner before doing anything, then remove that jb+. the dealer sees that jb+ your going to be paying more than what a scanner costs. Get rid of that intake too while your at it lol.

Why has OP not scanned for codes?! This is like diagnostics 101… figure out the code to see where to look… it’s so cheap to have a scanner lying around

Exactly what I said. This could go bad for him.

i removed every aftermarket mod that might be electrically related before taking to the dealer for service.

left on the hypercore because it was too much of a PITA to switch out.
dealer said nothing about the crankcase ventilation error code with the sensor wire disconnected from the turbo inlet.

did not get charged for diagnostic service because car is still under warranty.
i got lucky...i guess.

Yes, the dealer runs the ECU history so I have been transparent with them about it. I’ll keep everyone posted on what the issue was. Thanks again

You did everything but buy a scanner?

Hey OP if you're in SoCal hmu you can borrow my obd2 scanner.

Yes, we will now see if the extended warranty I bought is worth anything!

Extended warranty works the same as normal warranty unless the shop or advisor isn't transparent about mods. They will typically deny a claim if the vehicle is modded or the mods had anything to do with the failure. They don't want to pay for any repairs that were due to mods just like manufacturer warranty

Probably not since you modded and told them. Hopefully they’re cool about it. Let us know the outcome

Ok, mystery solved. There were two problems, both caused by me: The first was the cold air intake, where it connects to the turbo/engine was loose letting in more air than necessary and thus was throwing a lean code. The second was that after doing the spark plug change, I did not re-clip the high-pressure fuel pump sensor and it was loose thus throwing a fuel system code. The dealer removed the cold air intake and reinstalled the factory air intake and "fully seated" the fuel pump connector. The car is back to normal. I got to pay the dealer what I call a "stupidity fee" for them diagnose and correct these issues. I appreciate everyone's thoughts in this thread!
