Megaudlark Posted November 24, 2013 Posted November 24, 2013 Hi. I have a 2003 C5 2.0 HDI and the pump has stopped working.He height control in the centre console brings up the images on the display and changes them but the pump does not run.I have accessed the connectors on the front of the pump via the OS headlight and the command wire is dead but the twin plug is live. I ran a wire from the battery to the command socket on the pump but alas... still dead. PS ignition was on !!I am wondering if the pump siezed and blew the fuse for the command wire and if so where is it?Has anyone else had this problem or know what it might be. Obviously the car is not worth spending fortues on with Citroen dealers . Thanks for reading this. Any help would be wellcome. Quote
paul.h Posted November 24, 2013 Posted November 24, 2013 Welcome to the forum. The suspension pump has a maxi fuse MF8, 40 amp, according to the RTA French C5 manual. I think the maxi fuses are located in the engine fusebox but under the top layer which will need removing - but you seem to have a 12 volt supply from this. There is also a fuse listed in the glovebox fuses, F23, 15 amp - this should be listed in your handbook. Also check the pump earth connection. Somebody here had a pump problem and by using an earth wire against the pump body it would run - there was an internal fault and the pump needed replacing. Quote

Megaudlark Posted November 26, 2013 Author Posted November 26, 2013 Hi. Fuse OK and earthed pump body but still dead.I can change pump but worried about command faultTrouble is I can't drive the car to get it plugged in. Maybe there's a mobile service. I'll try to find out.With these dark evenings you don't get much chance to do anything so the job drags on !!! Quote
paul.h Posted November 26, 2013 Posted November 26, 2013 It will need plugging in to a dealer type Lexia to read faults on the suspension system, an ordinary code reader will only read engine codes. The post with the pump that ran when earthed is here http://www.citroen-owners-club.co.uk/citroen/topic/20241-c5-suspension-pump-fault/ Quote
Megaudlark Posted November 26, 2013 Author Posted November 26, 2013 Cheers, I read that and just realised that the command wire is dead so I don't suppose earthing the pump was worth trying until I put a live feed in the command socket. Weekend job I think for safety reasons. Thanks for help, I'll let you know of any progress. Regards, Mudlark. Quote
