I take it the starter doesn't spin at all. If the starter works with jump leads then the starter must be OK. If the battery is new then that is probably OK. If it doesn't start with the battery fitted then I should start checking the pos. & neg connections. The positive connection at the starter and the earthing straps - probably around the gearbox.
Many workshops that do Chip-tuning' now offer the service. Put "FAP removal" into Google and you'll find plenty. DIY guys simply remove the box, knock out the filter and replace the box but at least one of the Google advertisers offer a replacement stainless steel pipe - at a price.
I had the same difficulty when I did my C5 for the first time. Now when the job is finished, I switch on, wait a few seconds and then switch off. I do that routine several times before trying the starter motor. Don't guarantee that a C3 will be the same.
The C5 differs from previous Xantia, BX etc. The hydraulic pump is electric on the C5 and it springs to life as soon as the doors are unlocked, so by the time the engine starts, it's already at the "OK" height.
Not definitely - but it might be similar to the C5. If so, you'll need to remove the front bumper because the bottle is behind the wing. To change the pump, disconnect the wiring and the pump body just pulls out of the rubber grommet.
At 63000 miles you should be OK for a while. The early cars needed refilling with eolys at around 50K. Later ones go much longer - 80 to 100K. You'll get a message on the centre display telling you that the additive is low. If you ignore the message, the filter won't burn off the soot and your engine will go into limp mode (It won't rev beyond 3000) The ECU can be reset by anyone who has a Lexia. Several guys on FCForum have them. It only takes 10mins. Particle filters are becomming universal on diesel engined cars. It's the price we have to pay for "saving the planet B)". Different makes of car use different systems but from what I've heard, the Citroen/Pug is much better than some. It's possible without any adverse effect to have the particle filter taken out and the ECU rewritten so that all reference to the system is removed.
What year is your C5. C5's don't need to go to a main dealer for topping up - it's fairly easy to diy and eolys fluid can be bought now at GSF together with the kit. But then the ECU has to be reset otherwise false messages will be displayed. Regarding the FAP, some guys on the forums remove their filter and pressure wash it.
I'm sure they were being evasive. A select used car warranty is backed by Citroen UK themselves and not by the dealer. Therefore warranty work can be done by any dealer. If it were my car I would contact Customer Services at Citroen telling them that you were dissatisfied with the way their agent was dealing with the complaint.
Not a C5 - but somebody obviously fancied his wheels. Saw this in a service area behind Marbella. http://i69.photobucket.com/albums/i53/Johndug/ManilvaNov-Dec-2010041.jpg
AFAIK - the pump only gets power initially when it's first switched on, so check that first. Also there is a relay under the bonnet which is prone to failing.
The lift pump is in the fuel tank. You'll find it under the rear seat. Look for a big plastic bung which needs to be prised out. Check that there's power there when the ignition is switched on. If there is and the pump doesn't work, it probably needs changing. Disconnect the fuel lines and the electrical connector. The pump is held in by a collar.
Coastline is right! The 1.6 is a good engine - in the right vehicle, but the C5 is just too heavy for it. You would find it gutless. Saloon or Estate? What do you want to use it for? It's an estate every time for me but the rest of the family always want a saloon. Satnav? Something else to go wrong. I prefer to use my Tomtom. I can update it when I want to. Where to buy? If you know a bit about cars then you'll get a better deal privately, but if not you can always go back to the dealer
Not all would agree with you. When I advertised my 2.1 Xantia Estate on Ebay in 2005 I had enquiries from two English guys, both living in France. One of them eventually had the winning bid. I picked him up at the airport, brought him home to 'do the business' - then he was off to Dover for the crossing.
A cheaper option would be to look on Continental Ebay sites for headlamps. For instance here's a pair for around 280 quid. http://cgi.ebay.fr/Set-CITROEN-C5-01-04-LHD-european-headlamps-headlights-/370123785559?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item562d18c557
