Exhaust Flap short circuit HELP

[Shadows_mkv]

So I took my car to the dealer because it was throwing random codes at random times on my screen.

dealer told me it was my aftermarket BoostLogic exhaust.

Any ideas on what I should check or do? Or if anyone has had this issue?

fuse is not pulled

I attached the paperwork!

lmao. Those codes are not from the exhaust.

I mean, the one is for the valve, but the rest aren't.

As far as the exhaust flap goes. Probably have a removed fuse? That’s the code we all see when you pull the fuse to open the valve permanently.

As far as the other million codes, I have no clue. God speed

My car just started throwing the short to ground code on the valve. The only thing I notice is on a warm start, it does the roar with the valve closed when it used to do it with it opened. After that, it does open and stay open as intended.

No fuse pulled
JB4 on OEM valve setting
Stock exhaust
Started happening after my last track day

thats only the first page lol, I have 3 more pages

these are the other pages, pretty much the dealer blamed all of this on the “short to ground for the aftermarket valve exhaust”

so now im not sure what to do

Is that uh.. a print out of all of the codes?

Looking at it again, most are nothing/faults/etc. Maybe not even readable with most readers. It's probably fine. Remove the valve fuse.

Is your battery fully charged and the terminals secured on the + and - posts?

What was the error message on your screen?

lol nice of him to print the codes like that.

Looking at the other screen it only shows the 2 exhaust codes.
Did they by any chance, clear the codes to see if it comes back?

yes they were kind enough to print it lol

which one is the fuse? Turn car on open valve and then remove while on?

Cool. What did the message that came up on your center screen say?

Cool. What did the message that came up on your center screen say?

pretty much the whole saftey system turns off, chasis stabilization, cruise control

theyll pop up on screen and leave within 2 min then come back in min etc.. so there’s definitely a short

dealer claims the valve short is making everything else go off

 

[Shadows_mkv]

@zrk what fuse do I pull for valve? Pull when car is on?

I‘m curious because I want to do it. I don’t want any speaker amplification or exhaust flapping.
