Panda boost pressure control fault
Summary of the thread
A 2017 Fiat Panda is experiencing a boost pressure control fault, leading to a check engine light, reduced engine power, poor throttle response, and increased fuel consumption. The suspected cause is a malfunctioning vacuum switching valve, which controls the boost pressure from the turbocharger. The solution involves inspecting and potentially replacing the valve, with a recommendation to consult a qualified technician for accurate diagnosis and repair. The issue was resolved by replacing the faulty valve, restoring the vehicle's performance.

The vacuum switching valve, eh? Interesting! Where exactly is that located, and is there a way to test it without specialist equipment? I'm reasonably handy with the spanners, but I'm not about to start ripping apart the intake manifold without a bit more of a clue!

Indeed, the vacuum switching valve. The location may vary slightly depending on the exact engine configuration, but it is generally found near the intake manifold, responsible for controlling the boost pressure from the turbocharger, if equipped. While some rudimentary tests can be performed, involving checking for vacuum leaks or electrical continuity, an accurate diagnosis often necessitates specialized tools. Considering the potential impact on engine performance and fuel efficiency, I would advise consulting a qualified technician for thorough inspection and repair.

Thanks a bunch for the advice! Turns out you were spot on. Took it to a local garage, and the vacuum switching valve was indeed the culprit. New valve fitted, and the Panda is back to its old self. Cost me 140€ all in. Appreciate the pointer!

I am sorry to hear that you are experiencing such difficulties. I had very similar issues with my Panda – the symptoms you describe resonate quite closely with a problem I encountered not too long ago. Did you by any chance check the vacuum switching valve? I suspect that might be the source of the issue.
