My 04 AWD R is still showing DTC DEM005. which is a solenoid problem in the DEM controller. However the DEM controller was supposedly checked over by BBA reman who said the unit was OK, but I have had difficulty confirming 100% they were able to check to pressure switch and the solenoid.
Does anyone have a spare solenoid+pressure switch I could borrow for testing.
A full DEM controller is no use - coded to car but components are NOT.
The pump unit is fine. I've had 12V across the terminals and it rotates both ways freely. I had the chance of bits from an 04 XC70 - but waited for better weather - yard crushed it yesterday ....
Cheers
Bob
