Hi, just wanted to introduce myself. Bought my first citroen a few weeks ago, c5 auto diesel 2006. Its in desperate need of some tax but I love a good project. I'm a bit of a novice when it comes to citroens so Il probably be calling on you for some advice at some point. The c5 is in fairly good condition cosmetically, but that's where it starts going down bank. I've had to order a new rad fan, new driver and passenger front door glass. The suspension creaks like I don't know what, turbo only seems to wind in first gear, esp fault keeps popping up, and my biggest concern is the car judders then stalls when I put it in drive or reverse but don't put a bit of pressure on the accelerator. Yes, it's not in the best condition, but I've always fancied one and it was an absolute steel of a price so I couldn't say no!

Welcome to the forum.

 

It will be worth while you getting the Haynes manual for the C5. Also have a look at the C5 technical section and the pinned Common Problems post. Which engine is it ?

 

The suspension on the C5 does not normally creak unless possibly the rear suspension arm bearings need replacing - check for rear tyre wear and for them leaning in at the top.

If the 2.2 hdi 136 hp engine, then check at the gearbox end of the cylinder head for a broken plastic ball joint on the swirl flap actuator diaphragm - a new one is about £20.

On the egr valve check the actuator hose for splits at the ends, unless it uses an electric actuator.

It would pay to get a full diagnostic check for the faults including the turbo and the auto gearbox and others that may be present.

 

My biggest worry would be the auto gearbox and would get an estimate for any repairs to that before even doing any of the other things - on the basis that if it costs more than the value of the car then the other things are wasted money and you may be better sourcing a car in good condition.

Hi, thanks for the reply. I was a little concerned about the auto box when I went to look at the car, but it changes gear seamlessly, never over revs and kicks down bang on cue. I'm wondering if there is some sort of idle position sensor? The car drives well, and will do motorway speeds, it just takes longer than I'd expect to get to them lol. I know someone with a snap on diagnostic thing so I might get him plug it in and see what it throws up. Thanks again!

I would not bother with the snap on check, you need to use a Citroen Lexia diagnostic tool.

 

The 2.0 hdi should be 138 bhp. From a brochure, the hatchback 0 to 62 mph time for the 2.0 hdi auto is 11.3 seconds compared to 9.8 seconds for the manual version. The estate version is 11.6 and 10.0 seconds for auto and manual. Maybe you could time it to see how your car compares.
