Re: c5 fuse box b
The MAXI fuses are under the fuse box on a sceond "layer".
Mostly the pumps blow due to a build up of carbon crud inside and short. The pumps can be switched and the original ECU switched over. (have it cleaned and re-brushed before fitting it ?)

Similar to this in the C6
Pump removal
Two clips under the C6 top layer...not sure on the C5Pump removal

Re: c5 fuse box b
i checked the big fuse with a multimeter and its fine. the haynes doesnt have a wiring diagram for the pump, is the main power wire in the 10? pin connector on the front of it?

Re: c5 fuse box b
If you go to the front right where the pump is located you should see the wiring loom feeding it. Open the loom (Cut back the wrapping with a craft knife) there are three wires, two thick ones and a thin one, the thick ones are the live and earth, you can check if the voltage is getting there by pushing a needle into each and measuring the voltage with a meter.
If you have voltage there and the pump doesn't run then most likely your pump's died, you can further check by applying 12 volts to the thin wire which should cause the motor to run if it's good.

Re: c5 fuse box b
right, spliced a wire from the battery to the thin wire and the pump whirred into life, it didnt actually raise the suspension though. a brake master cylinder of a mk6 transit has the same thread as the fluid reservoir, drilled a small hole in it and pressurised the reservoir with air. didnt do anything took splice off and the pump still works as it should- opening the door etc, for about 20-40 seconds, but doesnt raise the car. also no smell of burning.
im guessing that means the pump is buggered

Re: c5 fuse box b
I think the pump itself is not 'buggered' if it runs, It might be the bsi on the pump but usually if the pump runs it should only need bleeding, are you sure there is enough fluid in the system?scas wrote: ↑29 Feb 2020, 13:10 right, spliced a wire from the battery to the thin wire and the pump whirred into life, it didnt actually raise the suspension though. a brake master cylinder of a mk6 transit has the same thread as the fluid reservoir, drilled a small hole in it and pressurised the reservoir with air. didnt do anything took splice off and the pump still works as it should- opening the door etc, for about 20-40 seconds, but doesnt raise the car. also no smell of burning.

Re: c5 fuse box b
yes loads of fluid. i loosened the small metal hydraulic line on the front of the pump and fluid came out-no air. is there a way of bleeding the system/

Re: c5 fuse box b
just looking at this-
viewtopic.php?f=3&t=59281&hilit=10+time ... 15#p573444
so i need to bleed it by turning the steering wheel, i thought the 2 systems were not directly connected. i presume im wrong?

Re: c5 fuse box b
The steering is supplied with LDS from the same reservoir as the suspension, but they are entirely different circuits.
To bleed the system follow my guide here from the relevant part on bleeding after the refitting section:
