In the handbook the fob battery replacement will only be a couple of lines in the section on the keys/remote so can easily be missed. If you provide a bit more info on your other C5 and its problems we may be able to help.

You are probably best to look at the parts diagrams which is a free service if you register as another professional and a member of the Citroen Owners Club. Use your VIN (VIS) top left to find your car http://service.citroen.com/do/changerParametres

If you have the car handbook it will say how to initialise the fob after replacing the battery. In our 2007 C5 handbook it gives to turn on the ignition with the key and then immediately press the fob lock button until it locks the doors which can take about 10 seconds. The Haynes manual gives the same so it must also apply to earlier cars. If this does not work then remove the battery on the fob and try again.

It could be when the clutch was done that checks on the dmf showed it did not need replacing, so a new flywheel solid or dmf was not put on. I would wait and see if the noise/symptoms get worse.

Welcome to the forum. You can read/copy/print the car handbook but it may need to be done in sections from here http://service.citroen.com/ddb/ You may need to select your language and then your car. Your dealer may also be able to get a copy. Sometimes owners put them in one of the drawers under a front seat so it is worth looking there. Citroen handbooks cover the full model range so some features that are on exclusive models only will still be included. If you need a workshop manual Haynes do not do one but if you are ok with French then the RTA one is good but the best one is the Citroen service box from such as ebay which comes on 3 dvds and is put on your pc. http://www.amazon.co.uk/Rta-B737-Citro%C3%ABn-Depuis-2008/dp/2726873758/ref=sr_1_1?ie=UTF8&qid=1445606693&sr=8-1&keywords=9782726873755

Welcome to the forum. The parts diagrams show the 110 hdi should have a dmf. If your car has been converted to a solid flywheel it gives you a problem if the clutch needs replacing since you will need one to match the flywheel. So you would need to know the make/model of clutch and flywheel fitted, from receipts or the previous owner or by removing the old one.

Looking at the parts diagrams for the TU5JP4 engine (1.6 petrol), they do not show a coolant level sensor.

A crankshaft sensor is an easy one to try first and from memory is only about £30 for the 1.4 petrol and take a few minutes to fit on the bellhousing at the top. Symptoms of these failing are they stop the engine when hot but once cooled down will let it start again but eventually it may not run at all. Since the engine will not run without this sensor it may not give a fault code so may not be found in a diagnostic check.

Just thinking, if the water pump failed they usually just start to leak a bit which over time gets worse but if the coolant is not topped up the engine will overheat, but if the bearing in it failed the timing belt could have jumped and then the engine could have stopped if the pistons and valves met rather than the pistons expanding and seizing in the bores. This though would also need expensive repairs of valves/possibly valve guides but the pistons may be ok but it would give no compression on a test.

If it is the AL4 gearbox you will not have a slave cylinder but on cars that do have them it is at the front of the gearbox.

Welcome to the forum. Maybe the garage prefers to fit a replacement engine than repair the existing one, then there is more of a guarantee that any potential heat related damage is overcome. If the engine stopped due to it seizing then there may well be damage to the pistons and cylinder bores and possibly bearings and crankshaft. The only way to check what damage has been caused will be to remove the cylinder head and have a look, then the garage would be able to give a better estimate of the repair costs. If you have the car at home then you could do some tests yourself without incurring labour costs, such as see if the engine can be turned over, check for coolant in the engine oil, remove the cylinder head and have a look for damage in the cylinder bores and the pistons. You could enquire at a Citroen dealer to see what problems are common on this engine from overheating but a general internet search suggests there could be damage to the pistons and cylinder bores. Cost wise I would suspect it may be lowest if you fit a second hand good engine (or depending on the age of your car just to scrap it and get another). This would limit the labour costs and you would know at the start how much it will cost whereas trying the repair route you will not know the cost until the engine is stripped down. As a minimum it would need a water pump, gasket set, timing belt, cylinder head checking for cracks and if ok possibly skimming but if not a replacement head, maybe new pistons/bearings/cylinder liners (if not a cast block), thermostat and coolant temp sensor since this must have failed otherwise there would have been a high temp warning to stop the car (unless this was ignored)

Welcome to the forum. Is the seat frame moving in the slides/runners that are fastened to the floor ? New parts are available for all the bits so if you can identify what is at fault then it should be possible to replace the faulty bit. I would think this would be a failure in the MOT test.

According to the Haynes manual - if you have manual air con, there are 2 bulbs in the back of the heater panel that can be replaced. It does not give the size of the bulbs. - The heater panel has to be removed first which means remove the radio, unclip the 2 trim panels at the sides of the heater panel and the retaining screws, remove the ashtray, remove the retaining clips and then the gear lever gaiter, unclip the lower part of the trim around the gear lever/heater panel and remove it, remove the glove box, remove the trim panel below the steering column, loosen the retaining screws and disconnect the blue control cable from the heater housing right side and the red cable from the left side, undo 2 retaining screws at the top of the heater panel then tilt it so it can be removed.

Welcome to the forum. I went from a 2004 mark 1 C5 to a 2007 mark 2 C5 and found the suspension a bit firmer, however, it could be a change of the lds fluid will help but it has about 5 litres so would cost about £60. It could also be a sphere needs replacing, this is from the Common Problems pinned topic: 44. How to check the suspension spheres. This topic contains useful information from coastline taxis on how to check which sphere is at fault if the suspension is hard http://www.citroen-o...ues/#entry83812 I find the intermittant wipe on the rain sensor is not as good as a normal timed one but just live with it and often prefer to manually push the wiper stalk for a single wipe. The windscreen needs to be kept clean in the area of the rain sensor so you could look at this. Standard wheels/tyres are 215/55/R16 for all the mark 2 C5s so somebody has fit non standard wheels to the car. It may be better to change the wheels to standard ones to improve the ride. The rattle could possibly be the clutch release bearing or it could be the dmf starting to show signs of wear. I have found the clutch pedal is harder on the C5 than other cars but you could try bleeding the clutch in case it was not done at the last 2 yearly brake fluid change. If it gets too hard then possibly the clutch needs replacing.

1 litre of fluid will be enough. First suck the old fluid out of the reservoir before filling it up with new fluid, then provided you have not got air in the system from disconnecting a caliper/pipe/hose/etc, it really does not matter which wheel is bled first. Front calipers may need about 250 ml each bleeding through to clear the old fluid and the rear cylinders about 100 ml each. Then you need to do the clutch (depending on what type of automatic you have), I have found the best way to do this is to suck the fluid out of the slave cylinder bleed screw (it will need undoing quite a bit for the fluid to flow, a lot more than a brake bleed screw) but keep an eye on the fluid level in the reservoir so you do not end up with too low a level so air is sucked through. Provided the new fluid container is kept sealed the fluid should last and it is probably better kept inside the house. However, you will probably only have about 100 to 200 ml left after the job so if you need to change the fluid again you will still need to buy another litre. Check the date on the fluid you buy, most of them have a foil seal under the cap but not always so the caps must be able to provide a good seal against moisture and they do not have a hole in them like on the car reservoir cap to let air in and out.

I have no idea about bluetooth but not accepting post codes seems to apply to all Citroen sat navs. We have a 2007 C5 vtx with the sat nav and I usually start with the town, then the street and then ok it. If just going somewhere I already know, I still often put in a town and ok it without bothering with a street just to see if the roads have a reported delay and these are then shown on the map.

Welcome to the forum. If the screen can be seen from the driver's seat I would think it goes off since it is not legally allowed.

Welcome to the forum. In the C5 Technical section there is a pinned topic on common problems to have a look at with steering racks leaks being one that appears often on here. On the C5 Questions About the C5 section there is a pinned topic on buying a C5 mark 3 tourer. You can read/print/copy the handbooks here http://service.citroen.com/ddb/ but you may need to select your language first and this should give info on the seats. Our C4 has switches on the steering wheel but these are too close to be able to read/use so are never used. I do not know the ATF change frequency but I think it is not something you can do DIY. If you specifically want the hydractive suspension, the was also a 2.2 hdi with it and that did not need to be an exclusive since they were all hydractive.

If you decide to get a code reader this one from Gendan is a decent price at £38.95 and gives some live data https://www.gendan.co.uk/product_FXNT200.html The 16 pin EOBD socket is in the glove box at the left side behind a cover that needs pulling off. The tank cap from a Citroen dealer is about £3 so it is not worthwhile going anywhere else for one. If the engine is the 75 bhp one it has 8 valves and the cam cover at the top of the cylinder head is narrow, if it was a 16 valve engine the cover is wider due to 2 cam shafts. In the VIN the engine type is included and for the 8 valve will have ....KFV.... You can see the VIN at the bottom of the windscreen and on the V5C document and the car Warranty and Maintenance book.

Welcome to the forum. Sorry I can not help but I have edited the title a bit so it is more obvious what you need.

It would be nice to know what the fault was, otherwise we have wasted our time trying to help and the topic may as well be deleted.

Welcome to the forum. It could be anything. Do you trust the dealer you bought it from, they might just be fobbing you off and it may not have been taken to a Citroen dealer for a diagnostic check ? If you do not do your own maintenance I would take it to a Citroen dealer and possibly mention it to the selling dealer. There were some recent changes to consumer law and a trader has only a few times to get a problem fixed before you can get your money back so is something to check. Your V5C registration document will give the name and address of the previous owner and you could contact them to see if they were aware of any problems. It might need a service such as new spark plugs or something such as an ignition coil, a new sensor such as the crankshaft sensor, a new accelerator pedal if its electrics are worn - to check it really needs a diagnostic check rather than just replacing parts hoping to get the faulty one before spending too much.

Welcome to the forum. If you need to contact the owner for such as an insurance claim/fine/etc. then you would need to go through the DVLA (or whatever they are called these days). Parking companies seem to have no bother tracing people this way so it must be possible. If making a claim, then your insurance company also would be able to make contact. There are also things such as facebook to try. Despite being a 1983/4 number plate, it still seems to be current on a 2005 1.4 C3 from the eurocarparts website. I have no idea why somebody would want this as a personal number plate since it does not obviously mean anything unless the black/yellow screw covers can be used to some effect.

I think hot means there has been many replies, how many to trigger this I do not know, something for admin to tell us or we could do a test but it looks as if it is at least 12 to 14.

Thankyou for getting back to us, I hope it was not too expensive to fix. I have slightly edited the title to help when searching.
