In this episode I attempt to find out why my Porsche Sports Exhaust (PSE) has lost it's snap, crackle and pop. I also got a coolant warning a few weeks before. We go through how the PSE and vacuum system works and the potential areas to troubleshoot before visiting the OPC or specialist.

First we look at the exhaust valves and actuators to find out if they are seized before moving into the engine bay to explore the vacuum system and electrical components which control the system.

We then move onto the vacuum system, the vacuum system controls the movement of the valves and if there is a leak or the solenoid controlling the system fail the car can begin to throw coolant warning errors or the PSE valves will stop functioning even when pressing the exhaust button.
