Year of Manufacture *: 2004
( Optional ) Engine Code or CC: td5

Hi

I have above with intermittant amber ace lamp on
fault codes using launch
hydraulic or mech fault in pressure control system
pressure signal out of range
direction control valve fault
hydraulic pressure too low
all intermittant codes
in live data system running, pressure is fluctuating between0.6 & 1.1 bar is this correct? seems low,i have read the pump max output is 135 bar
looking at the resoviour whilst running theres lots of fluid movement,leading me to a faulty valve block assay on the chassis rail,is there a return valve that sticks?
this unit is £960,your input would be helpfull
keith.

Hi

Can you give the corresponding fault code numbers for these codes?

Hello Keith,
I have changed a few pressure sensors in the end of the valve block, but I would check the wiring down to it on the offside inner wing for corrosion at the connectors also.

Hi

Thanks for your replies gents,after analyzing live data for sometime as the fault showed itself, system pressure fluctuated from 19 bar to 4 bar very rapidly
an immediate code read revealed the pressure signal out of range code,even with engine off

Replaced pressure transducer on the valve block & all works fine

Thanks again

Keith.
