After switching on the ignition, check that the PR018 “Hydraulic pressure” is between 40 bar and 50 bar.If this
is not the case, apply the interpretation for fault DF166 “Pressure sensor circuit”.
If the checks described in DF166 "Pressure sensor circuit" are correct and that PR018 "Hydraulic pressure"
indicates a lower pressure than that measured previously following activation of the pump motor, replace the
pressure sensor (see MR 411, 21B, Sequential gearbox, Solenoid valve unit: Removal - Refitting).
