Does anyone know what the fault code for turbo under boost is?

 

Octy went into limp mode, I pulled over, plugged in my code scanner, forgot to write the code, remembered it saying 'turbo under boost', restarted the engine, limp mode gone and went on my merry way.

 

Having read some of the turbo issue threads here, now I'm scared I'm going to face another big bill :(

 

FWIW: 57 reg VRS PD with 120k on the clock.

 

Many thanks, as ever, Briskodians!
