There's a mechanical safety valve that opens at 23 bar. Normal (maintained) operating pressure is 19 bar, dropping to about 11 bar after a pulse.

Unfortunately we've been told that before. I'm currently on my third PP hose.

My only concern now is that my compressor pump will be running continuously until the hose is replaced on Friday.

The ECM monitors operation of the PP system and if it detects that the pressure in the air reservoir isn't increasing at a pre-defined rate (ie there's a leak) it disables the pump and logs an error code. PP remains disabled until the error code is cleared.
