Exhaust fume turbocharger low side

Themythx · 04-16-2012, 09:47 AM

So out of no where today my check engine light popped on, so i drove and connected my usb to the procede and i got code 12543 which i looked up is Exhaust fume turbocharger low side... no idea what that means before i bring it to the dealer is it something i can fix on my own? Could i have installed the procede wrong? I have had it installed for a week and really haven't got on it yet so idk figured if i connected something wrong i would have got something sooner.
Install
Procede,DCI, exhust unplugged (golftee)

What stage and map are you on? Can you show a log with intake air temps?

to throw a 30FF with procede means you got a huge leak. Basically you are not even reaching the stock boost targets.
Check the vacuum lines that actuate the wastegates, those are prone to crack and there are TONS of threads showing pictures so just search. Could also be a wastegate that does not close anymore which means new turbo or turbos.

I understand that and i check everything i could without the pressure thing and everything seems... fine. I havent thrown the code since. Should i go to the dealer and have them look at it cause im not that technical lol i am about to put new DP's on tomorrow but i think maybe i should go to the dealer

Everything appears to be fine from these logs.

Enjoy the car.

This car is finicky. Disregard the code. Let the problems find you.
