Good evening,
I have a question about my Porsche sport exhaust on my Panamera turbo 2010. After pressing the PSE button, the valves did nothing, I replaced the solenoid and the vacuum from the engine works towards the left valve. After putting my finger on the right hose that goes to the right valve, I found that the left valve works after pressing the PSE button.
Now I think that the right valve is leaking and that it is therefore not drawing a vacuum.
