You are right Paul. We did think long and hard, but in the end the new C4 Picasso is a great car, and it only ever had one fault... The engine. The gearbox problems were caused by my local Citroen Garage's inability to make the engine and gearbox talk to each other. **** Guess where our new Picasso is NOT going if anything ever goes wrong..?? **** The 2.0 diesel in this car is apparently a new engine through collaboration with Ford, and it is not a typical Citroen/Peugeot engine in that it is very much more mechanical-sounding, but it sure goes when you stamp on the loud pedal. Which I eventually got to be able to do after the new engine got to 5000 miles. The nearest thing to a down-side is the fuel consumption, which is nowhere near the 60+ promised... Careful driving (below 80mph) will give you up to 50mpg in France (better diesel) and about 40-45mpg here in the UK. **** I'll post a report at about 2500 miles in the new car, which should be the middle of October as we're off the South of Frog 5 days after we take delivery at the end of August.

Please forgive the duplication if this has already been covered, but like many C5 owners, my car has given up injecting Eolys fluid into the fuel tank/system a long time ago. A very kind member of this forum tested the car and told me that the Eolys pump was not working. My question is: 1. Is it reasonably easy to disconnect the pump electrics and test the pump motor? That way I will know whether I need to replace the pump. 2. If the answer to the above is that the pump IS faulty, how difficult is it to replace? 2. When is the pump driven? Some people say that the fluid is injected every time the fuel cap is removed, and others say that it is injected at regular intervals. I want to monitor the pump drive with a voltmeter to see... All advice gratefully received.

Final Post in the life of CE14VMJ... C4 Grand Picasso 2.0 BlueHDi 150 EAT6 Exclusive+ At the end of the day, the following is the whole story. 1. The engine developed a fault sounding like a sticky hydraulic valve lifter at about 1600 miles. Many tests and audio recordings later it was decided by Citroen UK to replace the Injectors just in case the noise was injector based - it wasn't.! I then went off on my holiday to the South of France in September 2014, and I couldn't see the cars behind in the rear-view mirror for the vibration. Fuel consumption was rubbish too - 37mpg. That is disgusting!! I took the car to a Citroen garage in Frejus. They reprogrammed the injectors without the slightest hint of rolling eyes or staring heavenward, and they told me that they would fix the engine comprehensively if I left it there for a week. Sadly I didn't have enough days left to do that so we came home. SMOOTH DRIVE and 52MPG...! And we look down our noses at our Gallic neighbours..!! 2. Back home I chased up the engine fault to the tune of much sighing and looking anywhere but at me. Eventually after writing to the CEO of Citroen UK, the engine was replaced. BRILLIANT... 3. NO..!! GRrrrr...!! After 3 days I could feel that the gearbox was not happy, freewheeling when I took my foot off the accelerator at all speeds up to 60mph when the temperature was below 10C. Back to the garage to report it. Took a video of the actions to show them, left the car overnight several times for them to test it early in the morning, and after a lot of screaming and threatening to reject the car they decided to change the gearbox. At this point I was not convinced the gearbox was faulty, but, hey, who's the expert? 4. The gearbox was replaced and EUREKA... The new gearbox had the same problem. Back to the garage again... More screaming and shouting and threatening to reject the car... Suddenly out of the blue after I was told most emphatically that "...this is how the gearbox is supposed to work..." to which I replied with lots of nearly rude words because NO CAR is designed to freewheel at up to 60mph just because the temperature is below 10ºC. 5. Out of the blue, I was offered my money back less £1800 (£100 per month that I had owned the car). When I remonstrated and said I would rather have the car fixed, this was refused, so I took the money and ordered a new car (exact same model) from a different dealer. ****************** And now some poor sucker is driving around Kent in my old Picasso with a dodgy gearbox, because if the garage couldn't fix TWO of them, I doubt if their third attempt was successful if they even tried.... :o :unsure: .... The fault..?? The engine and gearbox ECUs are not talking to each other properly, so the gearbox is constantly in a form of default (limp home) mode. This was confirmed by a Citroen engineer in London who had the same problem on a DS4 with a replaced gearbox. They could not get the engine and gearbox to communicate properly until they unbolted the gearbox and re-bolted it in a very special sequence. Sounds a bit space-age-ish but apparently true.

Hi Paul, One would seriously like to think it is a detectable fault, but it currently appears to be beyond the ability of my local Citroen Dealer who has "looked at" the problem at least 8 times without getting any nearer to the answer. Now that the gearbox has been replaced, we can fairly confidently, rule out the gearbox as being faulty because the new one has the same fault. The only common denominator is the replacement engine, and any dedicated sensors or attached electronics. You are right about the fuel consumption, but considering that Citroen got together with a Japanese specialist gearbox builder (AIT) to build this torque converter box to be as close to a manual or DSG box as possible, the end result fuel consumption wise is disappointing. My 180,000 mile old 2.2 HDI C5 auto (51 reg with 4-speed auto) and pumped up to 175 neddies by Superchips at 55,000 does 45-47 on the motorway. You are also right about keeping the car below 70mph, which we do even in France mostly. That is where the 52mpg comes from. We had a 57 reg 2.0HDi EGS Picasso and over 70 mph the fuel gauge looked like a Rev Counter. Oh, well. We plod on...

Hi Paul. Update: ... The gearbox was replaced on 15 April, and after two days, the same fault was found to bew present in the new gearbox. I do not believe in jinxes and I firmly believe that the new engine was definitely the creation point for the fault in both gearboxes. At over £60 per litre the gearbox is delivered full, and is sealed for life (removal of and rotation - rolling around - does not result in oil leaks). I have spoken with several Diesel and electronics people and they all suggest the problem is being caused by a "rogue" temperature setting / sensor on the new engine or engine management computer (the gearbox has its own controller and calculates and implements shifts in accordance with instructions from the main ECU). After finally losing my rag with Citroen UK I have given them 30 days to sort it finally or I will be demanding a replacement car. When the car runs correctly it is absolutely fantastic, and the 150 neddies under the bonnet do their job extremely well. The only downside is the fuel consumption - 48-52 on a long trip and 40 around town. It does have, after all, a torque converter gearbox, which although I like the ETGS box on the 1.6 is just SOoo silky smooth when in operation.

After a long wait I finally took delivery of my 2014 Grand Picasso BlueHDi 150 Automatic on 2nd April 2014. Initially, everything was wonderful, but after around 1600 miles the engine was noticeably noisy - very similar to a sticky hydraulic tappet. After a lot of argy-bargy, and a few heated words, the engine was replaced under warranty in October. Not long after this, I noticed that when the morning temperature was below 5ºC, the car would drive like a car with a CV box - engine rises to a static speed (2000rpm) and the road speed slowly catches up. The gearbox changed gear during this time as it normally did before the engine change (hot weather then), but if I took my foot off the accelerator at any speed up to 50mph and in any gear up to 5th, the engine speed dropped instantly to idle (~800rpm) and the car coasted with no power to the driving wheels and certainly no engine braking. This only lasted up to a maximum 3 miles (longer when colder and shorter when warmer) before the gearbox and torque converter changed back to normal operation with engine braking and no over-revving when accelerating. Does anyone on this forum have the same car? They are as rare as a pint of hen's teeth, even in France, and I cannot find another one to compare with. Citroen UK is investigating but we are going to run out of cold winter weather long before any resolution is found.

Hi. A dog guard is listed in the C4 Picasso Accessories from Citroen.

After 12 years of extremely contented ownership - I can honestly say this has been the best car I have EVER owned :wub: - my beloved C5 is retiring. It has taken me and the wife and various friends to the South of France and back more than ten times with never a murmur - ever. The gearbox threw a tantrum in the Alps once, about 8 years ago, but 50 miles of slow driving fixed it, with no repeat to date. Before I send it to the great scrapyard in the sky (round the corner and up the road a bit, actually), does anyone want it for spares, in exchange for about £300-£500? It has covered 170,000 almost fault-free miles, and is fully roadworthy. It still does 45mpg tank to tank on a trip and 38-40mpg around town (in summer only - winter takes 5mpg off that). It has a superchips ECU mod (136 to 172 bhp) which made it SOooo much better to drive than in original specification. That is/was worth £500 by itself. It changed the car completely into a C5 that has done EXACTLY what it says on the tin for the last 120000 miles. Known faults / repairs required: Tiptronic shift needs attention (electronic problem possibly) - Auto function perfect. New spheres finally needed (170K... That is phenominal when I compare it to my old Xantia [60k] and XM...!! [40k]) 12/16V Swirl valve function is blocked by electronic function - all vacuum hoses recently repaired and functioning. EOLYS pump system needs some TLC. It only works every now and then. NO faults with particle filter. The door deadlocks stick intermittently at random (never more than one at a time), requiring unlock action from inside. Lubrication every 6-9 months fixes it. NO DENTS - plenty of small scratches, courtesy of old age. Spare radio and many other bits. I have replaced it - reluctantly - with a NEW C4 Grand Picasso 2.0 Blue HDI Auto, which cost me over £10k more than the C5, and isn't a patch on it. I will very possibly cry when my C5 disappears from my sight for the last time. :(
