Hello Sergio,
I have the same year car.
Three weeks ago I had similar problem, no power, warning lights on, it seemed with a piston off, etc.
I run the engine between 2000-3000 rpm ( just the engine, not the car ) "pumping" on the throttle for about 10 minutes.
After that I have driven normally and after one day the VSC light switched off.
I have connected then an OBD2 tester and it visualized the diagnostic code P0093: Fuel System Large Leak Detected.
I think to the following possible malfunctions:
- low or high pressure fuel pumps
- pressure regulation valve mounted on the high pressure pump
- discharge valve mounted on the common rail
- one injector temporary opened
Probably the malfunction of these devices should set other code errors but I didn't have it.
Fortunately the problem solved itself without any intervention.
I hope the same for you!
Bye
Walter
