Hi

my ACE system on Disco 2 is not working correctly. I will determine where the bastards have cut the instrument panel lamp wire. Previous

I've diagnosed the ACE subsystem on T4, and here's what I got:

PRESSURE CONTROL VALVE
48 ms - ON time (should be 4ms - 50ms)
1020 ms SYSTEM time (should be less than 90MS)


direction valve 1 and 2 parameters are well within settings.
I understand SYSTEM time is "time taken for pressure to reach upper threshold" (T4 Explorer)

If you have stumbled upon ACE valves problems before, please share :)


Oh yeah, it leaks from filter or drain plug..... a little.
