Hi there, - At the moment the suspension has not moved from the bumps stops. With the old pump the fronts lowered, but I put this down to the drier end cap leaking like a sieve. I did not notice any lowering when I had things working a little better. - I did not get a new relay with the pump. I...

Still broken. The pump will run but and build up gallery pressure. It seemed to slow down at 109psi and then drop the C1A13-64 fault as soon as I try to go up/down. No movement off the bump stops though. What seems to be happening is the Pilot Exhaust Solenoid is opening slightly and this will...

I stripped out the wheel arch liner and after some head scratching I realized the 2008 D3 has the wiring connectors behind the LH headlight. Checked for continuity - all good. Checked for voltage to the connector block by the headlight. No sign of corrosion or chafed wires. After reconnecting...

Wow, thanks for all of this. It helps to know what I am looking for when I access the wheel arch. What a crazy place to locate wiring connectors! I had to admit defeat and will tackle it when I get home from work tomorrow. I have the 4.4 petrol V8 in the LR3 and the 5.0 V8 petrol in the LR4...

Thanks to you both for the responses. I will go and check the connectors in the front wheel arch. It is almost 9 pm here.........I may need to continue the fun tomorrow!

The D3 is a 2008 and I replaced the original hitachi with an aftermarket hitachi style compressor. I rebuilt the old pump and it was working well other than the leaking end cap. I sealed it with epoxy and it worked okay for a short time. The only fault was the one related to raising slowly. As...

Update: I am not now sure the exhaust valve is the issue. I had been hearing a high pitch whine from the pilot exhaust solenoid. I unplugged and connected the pins to a 12 volt supply and the solenoid opened with a clunk and I could hear the exhaust open. To test this further I removed and wired...

I have just purchased a replacement Hitachi style suspension compressor (SKP) and have had c1a13-64 pressure not releasing when venting errors. Having read as much as I could and having checked several other things suggested on this forum, I tried to swap the exhaust valve from the old pump...
