Having had a few reads thru RAVE and reading of woes with burst pipes, fluid loss & possible pump seizure I'm curious if the following would get you home in the event of valve block-front/rear actuator pipe failure...?

Unplug the connector to the pressure sensor on the valve block, the ECU would see no pressure/sensor fault and would put the yellow warning light on & default to 'locked bars' condition, ie no fluid pressure would be passed to either of the actuators.
The pump would still circulate fluid through the valve block & back to reservoir and therefore not be damaged providing the reservoir was full and of course the HP from pump to valve block was OK but no fluid would go to the broken pipe or actuators....

...just a thought...:doh:
