Welcome to the forum. This is copied from a C4 Picasso handbook under the electric handbrake section: If the parking brake malfunctions while applied or if the battery runs flat, an emergency release is always possible (see paragraph “Emergency unlockingâ€) So fortunately if the battery voltage is down the handbrake can still be released, otherwise the car would be stuck. Citroens (and other makes) do not like a low voltage and the first sign is usually being slow to turn over on the starter motor and possibly lots of odd electrical faults (which you said you had - not turning over as quick and esp fault). With only 12 volts you were lucky to start the car. A good battery would be about 12.7 volts and about 14.4 volts when the engine is running if the alternator and wiring is good. Below 12.3 volts is considered as flat.

The op has not been on here since soon after posting, so I suspect the van is up and running.

The inlet sensor is part 1 in the diagram. From the Haynes manual you can clearly see the sensor in the middle of the heat shield at the front of the engine on the top of the exhaust manifold as shown in your diagram. To remove it it says to disconnect its wiring connector and then unscrew the sensor and remove it and its seal which should be replaced. It says to apply a smear of high temperature grease to the sensor threads before fitting - this could be copper grease as used on brakes. The wire should be put back in any support clips so it does not touch the heat shield, etc. If you still have the code reader I would check the fault code again, just in case it has changed and also look at the lambda sensor live data to confirm the fault - otherwise there is a risk you may be replacing the wrong part.

This is from the C5 Common Problems topic and I think was copied from a post by coastline: 14. Rear door will not open from the inside and outside. This has not happened to our C5s but it is a common problem. To fix: remove the door card, it is awkward with the door shut but can be done once removed, follow the rod to the door lock and remove the white plastic cover now try to look into the door and you will see the insides of the lock use a screwdriver and push the lever down on the inside of the lock and the door will open replace the lock with a different one.

A quick indication if the exhaust dpf has been removed or drilled through is to look at the inside of the exhaust tailpipe - it should be clean metal if the dpf is there and working - if it is sooty then the dpf has been removed or its insides knocked out or drilled through.

citrophile has rebuilt 2 turbos using cartridges but I do not know where the parts were from http://www.citroen-owners-club.co.uk/citroen/topic/21140-possible-turbo-failure/ http://www.citroen-owners-club.co.uk/citroen/topic/20684-turbo-renewal/ If you do go for a new dpf, keep the old one and then when it is cleaned you will have a spare or can sell it.

From the other topic on this car it is a 1.6 hdi with about 90k miles.

I have edited the topic title to include the car year.

The dpf may clear up so you could leave it for now but I would not put off fixing the injector leak. Where is the turbo leaking oil from ?

Welcome to the forum. You may need to try another code reader, which one are you using ? One thing that would give a code but not affect driving would be a catalyst fault shown by the outlet lambda sensor and you could look at live data on your code reader. If this sensor is switching the same as the inlet lambda sensor then the cat is at fault but if the sensor is switching at other values then the sensor may be at fault. If it is reading steady then the sensor may be ok. I would not replace any parts though without getting the fault code since it could be a waste of money.

Welcome to the forum. Depending on the engine size, some Citroens have a hand priming pump near the engine and it needs squeezing 10 to 20 times until it goes hard to fill the diesel filter. If you find the diesel filter, follow the pipes from it to find the pump. Ones without a hand pump need the engine turning over until it starts. If these do not work then possibly running out of fuel has damaged the fuel pump(s) or if you did not run out of fuel, the pump in the tank has failed making you think you ran out.

Welcome to the forum. Check the engine oil level in case it is too high and the engine is running on oil.

Welcome to the forum. I guess the previous owner has put the car in the auction since they could not fix the problems or if they could it was going to be expensive. Sometimes cheap code readers do not give the same definitions for faults as a Citroen specific one, so something to consider. As well as the car year, what mileage has it done ? On here on the Petrol Diesel LPG section: P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1) P1351 IDM Input Circuit Malfunction/ Ignition Coil Control Circuit High Voltage - this is likely to be the glow plugs so can be ignored for now. P1445 Purge Flow Sensor Circuit High Input P1457 Unable To Pull Vacuum In Tank P1471 Electrodrive Fan 1 Operational Failure (Driver Side) Initially it looks as if the egr valve may need cleaning (or replacing) and the MAF sensor needs replacing but you could disconnect this and see if the codes change as well as put it in limp mode but it is already in this shown by the lack of power. There are also other faults indicated so as noted by Randombloke, check the battery voltage and its connections since a low voltage can give lots of electrical faults. You may also need to look at the ecu connections as well as the engine fusebox. There is also something vaguely similar here and it is suggested to check the exhaust pressure sensor connection but the topic is not complete so it may not be a solution - to find it work back from the exhaust dpf pressure pipes. http://www.justanswer.com/uk-car/3l8vi-2004-307-1-6-hdi-anti-pollution-fault-codes-p0098-intake.html#re.v/417/ Later I will move this topic to the C5 section if I remember.

Welcome to the forum. How many miles has the car done ? Turbo failure on the 1.6 hdi is common and if it breaks up will write off the engine. When the turbo is replaced other things also need doing and then there are still no guarantees the new one will last. The oil feed pipe should be renewed and a filter in the oil feed inlet banjo should be removed. The sump should be cleaned out. There may be an excess of oil in the intercooler so this may need cleaning. There may be other things also that need doing. If you put off sorting the turbo, if there are any signs it has failed, stop the engine and do not run it again until the turbo has been replaced to help save the engine. I had one go on a petrol Saab and it had been giving smoke on starting, then showed some smoke on accelerating but when it went, a bit earlier it became noisy and then it surrounded the car with smoke. The dpf could be cleaned as a first step by water jetting to remove the ash and then it may be ok. It seems odd to be blocking if you are doing motorway trips all the time. Has the eoyls fluid run out or is it not being dosed. Check if the fuel filler cap still has magnets in it. Are there any fault codes ? If the fuel injector is loose and can be removed, then it is a case of replacing the seal on the end of it after cleaning out the carbon build up. If this job is left then the carbon leaking out will harden and make it very difficult to remove the injector but specialist companies can be found but may charge a few hundred pounds to remove it. If it is proving hard to remove, do not attempt it since the injector may get damaged and also need replacing and these are expensive. So this job should be done asap.

When selecting a garage, it will be better to use a Citroen one or a Citroen specialist since they will have the correct diagnostic equipment. You should check the oil level is not high, just in case the engine is running on the engine oil when it has been switched off.

You do not need to do a bsi reset or stand on your head and do somersaults whilst reciting something, just to disconnect and remove the battery. This is from the Common Problems topic: 16. Odd electrical problems caused by wrong battery disconnection procedure. If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3: - remove the ignition key from the car - open the bonnet - wait a few minutes for the BSI to shut down - disconnect the battery negative terminal When reconnecting - ignition key out of the car - reconnect the battery - wait a few minutes - insert the key in the ignition and wait a minute - turn the key to the first position and wait a minute - turn the key so the dash lights come on and wait a minute - start the engine - take the windows down and up to reset the anti pinch - reset the clock (and radio on the C3). Since our cars are kept outside, the doors and windows are closed whilst the battery is removed/disconnected. Then I open and close the door after connecting the battery before putting the key in the ignition and this has not lead to any problems. I could connect the battery with the door open but have not found this necessary.

If you have a meter also check the battery voltage, should be about 12.5 volts without the engine running. You will also find it will go to economy mode until you get the engine to run and then the radio and inside lights will not work but do not worry about this.

Pollution system faults can be anything that may have an effect on the exhaust emissions and usually will not be the dpf, eg a cam shaft sensor failure. I guess you have not yet had a diagnostic check. Fault code readers are cheaper than paying for a check. A fault that puts the engine management light on should be read by any EOBD reader such as this one from Gendan for £38.95 which also includes some engine live data https://www.gendan.co.uk/product_FXNT200.html If you need to do detailed checks on the car though you will need the dealer type Lexia diagnostic equipment. As mentioned above, I would also check the battery voltage and its connections. Should be about 12.5 volts before the engine is started and then about 14.4 volts. If you do try a bsi reset, make sure the gears are in neutral before switching on the ignition through the window. If you search the internet you may also come across different reset procedures. I suspect the fault is not the dpf since it appears before starting the engine and the dpf blocked is measured by a pressure sensor across the dpf which requires exhaust gases to flow through the dpf to give a pressure. Other sensors also require the engine to run for a few seconds before they can detect a fault, hence why the engine management light takes a few seconds to go off when starting the engine. Maybe doing the regen you are giving the battery more of a charge than it usually gets in day to day running or maybe the fuel pressure is a bit low on first starting - has the fuel filter been replaced as part of normal servicing ?

According to the Haynes manual, first remove the passenger glovebox, page 11.20 and then disconnect the blower wiring, release a retaining tab, rotate the motor anti clockwise and remove it, page 3.10. You can see the Haynes manual through the link above including the pictures showing how to do it.

Most cars I've had take a couple of miles to get up to temperature, possibly a bit more in colder weather. If much longer and the heater in the cabin is not giving out hot air by then, it is often the thermostat that is faulty, opening at too low a temperature. You could check if the radiator top hose is getting warm if the thermostat is opening too soon. I have even had this on a new thermostat. You should also check all the air has been bled out when the coolant was replaced after replacing the last thermostat, just in case the temp sensor is in an air pocket and not coolant. The engine cooling down after use is probably normal. If you want to check which steering pump you have, take a look at the parts diagrams using your VIN (VIS). This is a free service on service.citroen.com if you register as another professional and a member of the Citroen Owners Club. First easy check on the steering would be the fluid level.

Welcome to the forum. Some info here http://www.citroen-owners-club.co.uk/citroen/topic/23278-lexia-diagbox-pp2000-topics/

I have never had any problems getting the wheels balanced so just make sure where you go can do it. Our C5s have a hole in the middle of the wheel, if you remove the plastic cover to reveal the wheel nuts you will see. For wheels without a hole the tyre place should have an adaptor. if you can not find anywhere, get the wheels balanced at a Citroen dealer. If you did want to risk ruining your wheels by drilling them, they may then be weak but since it would be a modification you would need to tell your insurer.

The battery voltage before starting seems a bit low so it may need a good charge or replacing if more than a few years old. To check the lds fluid level you need to remove the cap and inside is a course strainer which extends down inside. The level should be just above the bottom of this strainer when the car suspension is at its lowest setting. I do not know how this level relates to the join on the tank but once checked with the strainer you will know. On later cars the tank is black plastic so the level can not be seen without looking inside.

The swirl valve actuator is low down at the gearbox end of the cylinder head but has a rod with a the plastic cup on the the end connected to a ball on the swirl flap mechanism but it breaks up. A new part (called diaphragm) includes the actuator for about £20 but it is possible to just swap the plastic cup from it. This only applies to the 2.2 hdi 136 bhp engine since this is not used on other engines. See problem 11. in the Common Problems pinned topic for info on replacing the diaphragm. In the end you may need to have a diagnostic check using a Lexia.

If you just need an aftermarket aerial they do not work as well as Citroen ones and the proper ones are only around £3 from a dealer, so I would not even bother trying an aftermarket one which could well be more expensive. Our latest C3 had an aftermarket one and the radio reception was poor but once the correct one was on the reception was good. On the C3 section there is a current similar topic on the aerial where an aftermarket one is not working.
