brilliant, that's a good point. Not being present I took his word that it was smoke rather than steam. I'll ask him if he's using it for any kind of distance or just around town. I'll tell him to take a good run and "give it the beans" to see if it helps.

Hi again, I had some brilliant advice from some of you previously when I was doing some work for a friend's C5 petrol 2.0 16v. Basically he was getting anti pollution fault, catalystic converter fault and oil pressure fault. So far I've changed the cat (which is pretty much the whole exhaust bar the back box), both lambda sensors and the oil pressure sensor. Citroen have run diagnostics on it a number of times and have changed the auxilliary fuse box, which is apparently a common problem. After all that there were no errors for a few weeks but they've all come back again. Add to that that it's hard to start when the weather is a bit colder and the car generally runs very badly. It stalls quite a bit and it has about as much power as an early 90s 1.0 micra. not good for a 2.0 petrol. This morning he called me and asked how bad is white smoke and a smell of egg. apparently he got this when the car started and after a few minutes running it has cleared and has gone back to "normal" (normal being the usualy crappy performance, not factory standard). He has checked the fluid levels are OK and there's no emulsification in the oil. I'm pretty stumped. I don't know what to advise him, other than push it into a river. Any suggestions would be very much appreciated. cheers Nj

that's what I was thinking but my friend took it to the dealer yesterday and the diagnostics read 5 different error codes so they're going to change the fusebox today. I thought that was a bit odd but after a bit of research it seems like a particular problem with the C5. It's going to be a bit annoying if it was just that and my mate bought a new cat, which I fitted, for nothing. especially since I cut the old one in two to throw into his boot. still, if it's not the fusebox that leaves things open for the garage to start changing everything in sight. oh dear...

New cat fitted and left the battery disconnected for ages but the engine warning light and emissions light are still coming on. Does it need reset by the dealer with diagnostics or should the battery disconnect have done it? If disconnecting the battery should have done it then maybe I have to change the oxygen sensors too? I'm not sure what else, other than the O2 sensors, would cause these issues. aghhh!!! cheers nj

Brilliant, good enough for me mate. 9 years maybe isn't enough to soot them up too badly. I'll try the new cat to start with and see how that goes. cheers nj

Online Automotive have given me decent prices and will deliver to Finland. The question now is should I replace one or both lambda/oxygen sensors at the same time? I'd be incline dto say yes but at £47 and £87 plus vat each they're not cheap

I'd really appreciate first shout on that motor if possible mate as the rev counter isn't working just now and ebay sellers want to sell the full speedo unit, which is fair enough cheers nj

erm.. no idea. my finnish is rubbish :) But I'll get my wife to have a look http://www.biltema.fi/ onlineautomotive say they can ship to finland so I'll check both options. thanks for the pointer. Had no idea about Biltema although a local parts store did tell my mate he'd been looking at €400ish so onlineautomotive's prices would be way better

Ah.. good old angle grinder. beats WD40, rostoff etc and any amount of socket and ratchett shenanigans any day. Definitely good to get new hangers and whatever kind of brackets Citroens use for the flanges. I've emailed to see if they can deliver here so I'll update the thread with what they say and notes on the fitting of the cart once I have one. Probably best stick a new lambda/O2 sensor on there at the same time.

excellent, thanks John. I'll contact them to see if they'll ship over here. Looks like the flange of the cat will be quite far up into the engine bay so only way to know for sure will be to get under the car and get the undertray off. I'm wondering what kind of system is used to fasten the flange to the exhaust manifold or downpipe, whatever it connects to? Hopefully a simple bolt on bracket. I'll check this before ordering in case it has seen better days and needs replaced at the same time cheers nj

Sorry, what an amateur mistake. it's a 2001 2.0 16v estate LHD (not sure the LHD will make a difference though). Yes, it's the anti pollution warning light that has come on and the citroen garage have told him he needs a new cat at something around €700 plus fitting plus vat thanks nj

Hope it's OK to revive an old thread here? Thanks to this forum I managed to take a friend's speedo gauges out and swap over the stepper motor from the speedo to rev counter. So now his speedo is working again. Amazingly the garage here in Finland (we're both Brits living in Finland) declared that he'd need a new dash (at much more than £200 sterling) and said it would take a full day to do the work. literally thousands saved there. So now we have the rev counter stepper motor not working and I wonder of anyone has since found a way to order this part directly? Or would anyone have an idea of what other cars will have the same stepper motors so we can get a set of speedos from a scrappie and take a stepper motor from them? cheers Nj

Hi, I'm new to the forum as I'm usually into german cars but have been helping a friend with his C5 recently. We managed to find broken wiring that was giving a duff brake pad wear indicator light and also, thanks to this forum, I managed to take his speedo gauges out and swap over the stepper motor from the speedo to rev counter. So now his speedo is working again. Amazingly the garage here in Finland (we're both Brits living in Finland) declared that he'd need a new dash and it would take a full day to do the work. literally thousands saved there. So now we have the issue of an intermittent emissions warning light and the car has stalled on occasion. Also at times it lacks power and wil suddenly clear. The combination sounds to me like the cat has collapsed and the innards are blocking the exhaust system at times. We can probably find a cat here (although recommendations for a supplier who ships within Europe would be welcome) but I don't know anything about the exhaust system so would like some advice. Does the cat attach to a downpipe somewhere near the gearbox and is it easily accessible for changing? A quick search online suggests that the cat incorporates a huge bit of piping too, possibly going the whole way from the downpipe to a back box? Would that be anywhere near correct? Many thanks in advance for any help that can be offered cheers Nj
