Am I sad enjoying this thread? You better fix it now

I think it is always good advice to disconnect the battery before disconnecting any ecu. On the C5 the suspension pump stays live when most other things are shut down so disconnecting the battery before unplugging or plugging back in the pump is probably a must. On the Technical section there are pinned topics, one for a bsi reset and another of common problems which has a procedure for just disconnecting/reconnecting the battery to avoid odd electrical faults.

I think you may have misunderstood me Paul, someone had the suspension pump multi plug removed before I acquired the car, I wasn't familiar with the setup so connected the battery and went through the BSI reset. It was only when I was digging around the pump after checking the fuses that I realised the connector was off the pump. I took the pump off the other day and tested it off a battery and the motor is spinning but I discovered that not only was the multi plug removed but someone had the single 'command' wire disconnected too! I'm going to fit a pump I took out of a 2004 car seeing as I went to the trouble of removing it. Might be a few weeks before I get back at this but at least I seem to be making progress. Thanks for opinions and assistance.

Maybe the previous owner disconnected the pump if it was running all the time and draining the battery. The plugs are also known to come loose so an occasional check is needed. There was also somebody on here who ran their own supply wire to the pump with a timer when the control developed a problem and found this a low cost way of keeping the suspension up.

Time will tell! With a bit of luck I might find some time to fit the pump this week. I'm itching to get it fitted to see if it works! If it works I will be elated but if not then the car could be on borrowed time.. Will update as soon as I get the pump back in. Incidentally what is the Capacity of the LDS reservoir/system? Thanks for the help.

[paul.h]

The service box procedures give the suspension system lds fluid capacity as approximately 4.8 litres.

Thank you Paul.

A little update. I fitted the suspension pump from a 2004 c5 hdi and reconnected the command wire and multi plug, refilled the lds reservoir and reconnected the battery, started up the car but unfortunately I still have the message 'serious suspension fault'. It's looking like I need lexia involved which I unfortunately do not have nor am I in a position to purchase at the moment. It's probably no use doing a BSI reset but I might try that at the weekend. I'm feeling a bit deflated like the car! I thought I had it cracked when I saw the command wire disconnected but maybe the suspension is 'locked out' or something like that..
