EWG Failure

This is a repost from the maintenance sectionn. Looking to see if it'll get more views

A quick question.

What are the symptoms of an EWG failure? I hit the rev limiter today responding to an out of state family emergency and heard a pop. Getting error that max power output is not available and I think I hear the turbine. Unfortunately I don't have a code reader. The engine stumbles a little at start up. Top side of the charge pipe appears to be intact.

The car is sitting as I'm not supposed to drive home until tomorrow afternoon.

I'm wondering if I can limp the car home.

2015 435i N55, MPPK. 60k miles.

Try to run your hand around the charge pipe. If it's stock, they usually crack around the connection to the throttle body. May not be noticeable from the top.

Found it. Charge pipe broke off at the throttle body. Time for some duct tape.

Similar thing happened to me running jb4 map 1 which peaks at 12.5 psi. Forgot I was in manual shift mode and gunned it. Bounced off the rev limiter and CP blew. Took me an hour to limp home(kept rpms below 2k). That was 5 ish years ago and the car is still running fine.

I hope a metal chargepipe is in the mail. If you can get an intercooler and do the cp and intercooler swap at the same time.
