Hi guys. After along time I finnaly was hable to read the error codes on my gt (I was grounding the abs plug instead of the ecu one :bang::bang::bang::bang.
And I got the error 2134 - Over-boost electrovalve (Pierburg valve/PBV) malfunction - short or open circuit.
I have a boost controler that the previus owner put on the car. And the pierburg valve has no vacum pipes going to it.
How do I fix the code? Cant find anything on it.

is the pierburg still plugged in? i recall i put one of these on a gt many years ago and it needed to be plugged in to stop the light.

The pieburg valve is there. It had 1 vacum pipe on the side that only has 1 conection, I took it out and blocked that vacum line. i dont know if its connected to the wiring, Will check.

it needs to be plugged in whether your using it or not, bit of luck you plug it in and the light will go away. If not then assuming there is no issue with the wires themselves plugging a working one in is the only way for it to not put up the management light.

If you not using it then it needn't have any vac lines going to it at all

It would bee the back plastic with the 2 prongs right?

Yeah looks like the right part , it’s under the plastic cover in the middle of the engine bay .

yes that, its a good idea to blank the unused vac ports off to prevent debris getting in there and stopping it working cause that will make the management light come on.
