Is 10w-40 oil recommended in the car Maintenance and Warranty guide, in the Haynes manual it gives 5w-40 for diesels ? Our 2007 C5 uses 5w-30 INEO ECS. From the compression tests at least you know the fuel injectors are not seized in if you ever need to do any work on the cylinder head. Were new injector seals used when the injectors were put back ? If it happened due to the oil change then its likely to do with the hydraulic tappets on that cylinder - maybe they drained or seized or the oil supply is not going to them.

Just need to ask, is your car an automatic gearbox or 6 speed manual ? From a 2007 sales brochure the official mpg urban / extra urban / combined for the hatchback is 36.2 / 56.5 / 47.1 mpg for the 2.0 hdi 6 speed manual and 28.2 / 51.4 / 39.8 mpg for the auto 6 speed. It gives identical values for the estate version 2.0 hdi. For our 2.2 hdi estate 6 speed manual it gives 34.4 / 55.4 / 45.6 mpg which considering I get 45 to 52 mpg on motorways suggests you should be getting a lot more than you are if you have a manual gearbox. My driving style though is steady and not hard acceleration, changing up a gear as soon as the engine has enough revs (probably 2000 rpm or a bit less due to it being a diesel), keeping to or below speed limits, not using cruise, gentle braking and lifting off the accelerator pedal early when needing to slow down, not driving close, not racing up hills and not accelerating down hills. Have you reset the trip computer ? This is done by holding in the button on the end of the wiper stalk. Also once 9999 km (6248 miles) is reached it stops working and needs to be reset since it does not have enough digits to go higher. If you have not been resetting the computer try doing it before each trip to see what it thinks you are getting. I find the town driving sections hit the fuel economy badly. A quick check if the brakes are binding without jacking the car up is to feel the wheel hubs to see if they are hot.

Before the oil change was the engine ok, just thinking whether you have used the correct oil and also if the oil has drained out of a valve tappet. When changing the oil did you do anything other than drain the oil, replace the oil filter and then fill with oil ? Sometimes Citroen number the cylinders from the gearbox end, how did the garage decide there was no compression ?

Welcome to the forum. Hopefully you have got your van running by now. Did it run out of diesel and cut out but showed as if there were another 50 miles left in the tank before it would run out ? Was the balloon priming pump used until it went hard and fuel could be seen in the fuel pipes ?

I think holding the lock button down is to re-initialise the remote key since this is done if the remote battery is replaced. So just ignore this bit.

From your previous topic your car is a 2007 C4 automatic, but you have not said which engine. If you provide the engine info we can look at the Citroen parts diagrams. From the Haynes manual it gives: 1.4 litre ET3 engine Bosch VR8SE 1.6 litre TU5 engine Bosch FR8ME or FR8SEO 1.6 litre EP6 (vti) engine NGK PLZKBR7A-G or Beru 12ZR 6SP03. The 2 litre petrol engine is not covered by the Haynes manual. The latter ones are likely platinum electrodes for a long life and Beru ones will be supplied by a Citroen dealer and may well be a lower cost than from eurocarparts since 2 years ago for our C3 it was £34 for 4. You may be best to use the Citroen recommended ones to help the life of the ignition cassette, never mind what eurocarparts have in stock.

You may have your door unlocking set up so 1 press opens the driver's door and the second press opens the rest. On our previous C4 this was set up via the radio menu and possibly configuration. This feature I had on other cars and is to prevent other people getting in your car as a security measure.

Do you have any lottery numbers for Saturday, this could be your lucky year after the previous one and turbo failures.

I would check the amount remaining does not include the 6mm of metal backing material, it would be better to be clearer and say friction material remaining x mm. As John says, new front pads have 12 mm friction material. The rear pads may be a bit less (shoes a lot less) but on the 2001 to 2008 C5 they have cut outs at the leading and trailing edges and they wear a bit wedge shaped partly due to the rear shims only covering half of the pad. To actually see the rear pads needs the pad cover removing since the ends have the cut out and if the rears are seized or there is corrosion on the caliper/suspension joint, the inner pad can be worn down without noticing.

Welcome to the forum. There are very few Pluriel owners on the forum and there are sites that specialise in just one model which are often worth looking at, whereas on this one all Citroens are covered with the C5 being the most popular. Sorry I can not help with your query though since I have always had manual gearbox cars.

If it is hilly I have read that cruise can use more fuel going up hill since it will try to maintain the speed compared to letting it drop a bit which will save fuel. Possibly if needing to slow down cruise will keep up the speed until the brakes are used whereas without you would lift the accelerator a lot sooner. We need adpace8 to try 2 identical trips with and without cruise.

We had this post on a tailgate not opening due to low battery voltage which made me think of checking it http://www.citroen-owners-club.co.uk/citroen/topic/21222-is-it-easy-to-change-the-battery-in-c5-tourer/

I would check the wiring between the body and boot. In the estate/tourer (and other model hatchbacks) it often breaks in the rubber tube between the 2 so is a possibility. Also check the battery voltage in case it is low.

If it is the original radio it will be coded to the car and will not require a code to be entered if the battery is disconnected. If you keep the key out of the ignition switch I would not think you need to disconnect the battery but if you do decide to disconnect the battery do not do it too quickly since the bsi (cabin fusebox) needs time to shut down - there is a procedure in the C4 technical section pinned Common Problems topic you can use,

From your introduction post your car is a 1.6 hdi but what year is it ? Have you tried using the spare key ? I do not know if this applies to the C5 but on a C4 you can change how the doors unlock from the remote through the radio menu so 1 push just unlocks the driver's door and a second push is needed to unlock the passenger doors. Our previous C4 also had an update to stop the time and date resetting and this changed how the remote unlocked the doors - 1 push unlocked them all but once moving and using the autolocking, when you stopped and opened a front door the rear ones no longer unlocked so they could be opened from the outside unless the remote unlock button was used.

That is what I was thinking, I find on our C5 estate 2.2 hdi 173 bhp and our previous C5 hatchback 2.2 hdi 136 bhp that if you go around 65 mph you get another 5 or more mpg compared to 70 mph. Much above 70 mph and the fuel use increases a lot. On the M60 there is a section of roadworks for 20 miles at 50 mph with speed cameras, through this section the fuel use drops dramatically. Last 2 days I went from Warrington to Lincoln and back, 130 miles each way of which 2 miles are town roads, 25 miles a 60 mph limit and the rest motorway - going gave 47 mpg keeping to the speed limit but return was 51 mpg keeping to about 65 on the motorway (apart from an 11 mile queue on the M60 on the return). The same journey in our C4 1.6 hdi would give about 70 mpg. Wind direction can also affect fuel use. I often think when the large 4x4 cars go past in the 3rd lane at over 80 mph they must need to stop frequently to refill the fuel tank and lose the time they saved by driving fast, never mind being a danger to everyone else on the road.

Thankyou for getting back to us, I hope the new spring fixes the problem. The Berlingo site in the links might be worth joining, there seems to be a lot of good info in it.

what mph are you doing on the motorway ?

A search came up with the possibility the load sensing valve (rear brake compensator valve) just needs a new spring for £22 http://www.ebay.co.uk/itm/Citroen-Berlingo-Brake-Compensator-Load-Proportioning-Sensing-Valve-Spring/222000945358?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3De99d62541a4e4e5598eda78c5bd26188%26pid%3D100338%26rk%3D2%26rkt%3D12%26sd%3D221582091213 Or maybe the existing spring needs greasing http://www.berlingoforum.co.uk/thread-2502.html This includes a picture of the valve on the rear axle http://www.berlingoforum.co.uk/thread-3635.html According to Citroen's procedures, to adjust the spring length the van is put on a 4 post lift, the height of the back measured above the ground (wheels must still be on the floor), the front and rear brake pressure measured and then the spring length adjusted so that the rear pressure is correct against a value on a graph. Once adjusted the pressure measurement tool is removed and the brakes are bled in case air has got in to the brakes. If the van does not have abs it is a bit more complicated needing the van weight to be calculated and then a load is applied to the rear and the pressures compared to a label on the bulkhead.

I think the left is wiring and right is the window wash water pipe. If you squeeze the tube you may be able to confirm this. Try pulling/squeezing the tube out at one end to remove it to see the wires. To help it go back a bit of washing up liquid will help it slide back in place. Some pictures here show the wires and damage https://www.google.co.uk/search?q=c4+tailgate+wiring+damage&espv=2&biw=1172&bih=855&tbm=isch&imgil=1t3YqnF-HzVhPM%253A%253Bnv4xC_fMrof3vM%253Bhttp%25253A%25252F%25252Fc4owners.org%25252Fplugins%25252Fforum%25252Fforum_viewtopic.php%25253F186617&source=iu&pf=m&fir=1t3YqnF-HzVhPM%253A%252Cnv4xC_fMrof3vM%252C_&usg=__wVfTwWdUzfLTOtOpBiINrurvIwA%3D&ved=0ahUKEwj296GyyvXKAhUBwxoKHczuBD0QyjcINA&ei=T5K_VraUKoGGa8zdk-gD#imgrc=1t3YqnF-HzVhPM%3A

Welcome to the forum. This is for a 2007 C5 and may apply to your car. The control switch is at the left side under the steering wheel and has a slide switch to select cruise or limit, an end button and 2 side buttons. To use cruise, slide to the cruise position and when travelling at the desired speed press one of the side buttons. The selected speed is displayed on the speedo panel (your car may be different). The accelerator can then be released and the car will maintain the set speed. To adjust the control speed whilst in use, the top side button increases it and the bottom side button decreases it - each press adjusting by about 1 mph and a continuous press by 3 mph. Cruise is disengaged when using the brake or clutch pedal, if the gear lever is in neutral or if the end button is pressed. Cruise can be reactivated by pressing the end button or if a different speed is wanted by pressing a side button when at the desired speed. To switch off cruise, slide the switch to the O position or stop the engine.

Welcome to the forum. It might be due to a rear load sensing valve. have a look at this topic http://www.berlingoforum.co.uk/thread-1366.html

Those are probably the manufacturers part nos. You could get the VIN from both cars and use these in the parts diagrams to see what differences the cars had. The parts diagrams are a free service if you register as another professional and a member of the Citroen Owners Club. Use the VIN (VIS) top left to find the cars and check the Citroen part nos to see if they are the same. Also at the left side look under Characteristics to see what features the cars had. http://service.citroen.com/pages/index.jsp - you may need to select your language first. On the parts diagrams the ecu can be found under Mechanical / Air and fuel supply / Inj calculator sensor If you have the make of the ecu you could try a search against the make and the part nos you have given. The make could be Bosch, Sagem, Siemens, Magneti Marelli.

Another question, did the auto gear fault ever come back after the brake pads were replaced ?

All the wires to the tailgate go through the rubber tube so possibly a few of them have broken or maybe just the earth wire. This is from the C4 Technical section Common Problems pinned topic and it may be worth contacting your Citroen dealer in case they may do the repair free of charge: 13. Tailgate electrical faults - rear wiper, lock. Caused by wiring between the car body and tailgate in the rubber sleeve breaking. The broken wires need joining, possibly with new sections. Some cars may have been repaired with Citroen paying. You can read/copy/save/print in sections the handbook from here but you may need to select your language first. It includes from 1/10/2006 but this probably applies to earlier cars http://service.citroen.com/ddb/ Under the section 'Remote control' it gives: Re-initialisation of the remote control After a change of battery, it is necessary to re-initialise the remote control. To do that, switch on the ignition and immediately action button A (door locking button) on your remote control to trigger the action desired. This may take some ten seconds. I have moved your topic into a C4 section since ones outside of one may not show after a few days and then become difficult to find.
