Hi Guys, so over weekend I did more then 220 miles, where 85 miles was longest journey. Only thing is, steering wheel shakes a little approaching 65 mph, but very gently. Maybe it is because garage convinced me to buy cheap evergreen tires.... My previous C5 was driving much better, even 120 mph (in Germany) was very smooth. I am starting to think it was this weird, one off thing. I will probably do another 500 miles before I will go to camping trip in Alpes - hopefully it won't break there!

Hi Guys, thank you for your help. I got car back from garage in Friday - they haven't done anything except injector testing. Since Friday, I drove 6 x 30 miles and nothing happened. So garage did test on injectors - they said they connected them to pressure measurement machine and one injector sometimes don't give enough pressure. According to them, its returning lot of fuel to tank and it makes disturbance in rail which makes fuel pressure drop and engine dies. But I am not convinced: * first, I don't see this could cause such disturbance (well, I need to learn now more about common rail systems) * second, I don't want to change injector My plan for now is to: * check ECU in authorised garage (or TRUSTY garage north from Thames in London - please PM me if you know someone) * check injector pressures @paul.h Thanks for advice! I will be very careful.

Hard to say. Since like 500 miles coolant keeps level. Torque is one think I may check later, but my garage seems to be quite popular and I don't belive they could make such mistake. When I will get car back I will try to move crankshaft sensor cable to see if it will cut the engine (need to think how though). Is there some resource with technical schemas? Unfortunetelly Haynes shows only how to change things, I would like to learn more how car is working - maybe I could understand myself what is wrong...

How is this possible that it happens every several miles and rapidly? For my understanding, sensor won't give any signal, but for my understanding it should causing an error since ignition is still 'on'.

I called garage and again they can not find any issue. They will try to measure fuel pressure in injectors - they suggested maybe one injector does something with pressure in fuel system and makes engine cut off due mechanical failure? But they, why it would refuse to start again since it was mechanical? Is it ever possible that mechanical failure would cause engine cut off without any feel, like choking? Another thing, suggested by mechanic, is ECU problem - it might not store errors. What do you think? Symptoms feel like camshaft/crankshaft sensor, but error should be stored, right? Are there any circumstances that it might fail silently? Could it be something with wiring - as I mentioned, we had similar issue before, maybe sensor is faulty? Also, is this possible to use cheap ODB reader to detect faults? I read that Lexia is better, but in which way? As I would like to learn more, are there some manuals/schemas how fuel system is build in my C5, what would you recommend?

Hi, thanks guys for your answers, I really appreciate this :) I would put another part of story: So after a year I bought a car, I put to local garage for cambelt change and oil replace - it was around 15th of April. They also found error on camshaft sensor and replaced it. After aprox. 20 miles after leaving garrage, engine stoped, and we were priming it for like 5-10 minutes, and its started. After another 40 miles, it stopped again - this time cannot started. My friend asks local car 'magician'. He came, and apparently he cleaned camshaft sensor - it was wet and around 1.5 litter of coolant was missing (I bet this was garage fault, as they were fitting water pump as well). He connected car to some device, and restarted car by pulling 'master error' away. I put car to garage next day and they said connectors on camshaft sensor were 'loose'.... And car was running well until service - when they changed also fuel filter. Then story described in first post happened... I have few more questions: 1. Does fuel pressure relief valve is inside high pressure fuel pump, which is driven by cambelt, right? 2. Could cambelt job cause the problem, I read somewhere that wrong tension might be case: https://www.rac.co.uk/forum/showthread.php?1861-306-HDI-High-Pressure-Fuel-Pump 3. @mhedwig fuel filter seems to be very easy repair to perform, is this really possible by garage to fail it? People in garage are very nice (well, I left there in total 1700 GBP for cambelt, oil change, front pads and brakes, service, mot), but this missing water and possible bad job on fuel filter is worrying... PS. I bought https://www.amazon.co.uk/Stoga-CAN-BUS-ENGINE-SCANNER-Diagnostic/dp/B005FOIC3I/ref=sr_1_2?ie=UTF8&qid=1497174764&sr=8-2&keywords=odb%2Breader&th=1 what is your opinion about this unit? Best!

Hi Guys, I have following situation with my C5. 2.0 HDI DOHC. Around 1 week ago, during driving around 50 mph, engine shut off. There was no signal diode, it just stopped to work. I could car inertia to get to safe place. Only think I new I can do was to use rubber fuel pump. After few squeezes, I tried to start and it worked. I was able to drive remaining 35 miles or so. This situation was around 80 miles after service - including fuel filter. So I put my car back to garage, but they found nothing (and haven't charged a penny ;)). But yesterday, it happened again - and it was stressful, as my family was on board. First time it started after few rubber pump squeezes, but next 2 times were much worse - we had to (me and my wife) use starter for about 3-4 minutes until it started. And last time it was turning off several time on idle, and when we decided to drive, car choke 2 or 3 times, but eventually we manage to get last 20 miles home. It was rather stressful as we were on M25... So my question is, what could be culprit? I know it could be lot of things, but maybe you could at least give me some clues? I was reading about fuel pump failures or even faulty electric connectors. What makes me think, when it dies, I don't see any diode like check engine - could it mean that ECU might not be involved and fault might be mechanical? I was thinking (or read somewhere) about faulty air, could it be a problem? I would also like to know if there is some cheap device I can buy to check engine errors by myself? Best!

Hi, I will soon move to London, I own now C5 and would like to have same car here (won't bring mine for obvious reasons....). Sadly, it means I will need to buy a old car, and I don't know prices here, could you please share how much I can pay for typical repairs in good garage? For example: - timing belt replacement - brake disks and pads (in Switzerland its 1000GBP o_0) - parking sensor - suspension pump - any other costs are more then welcome! Anwser would help me choose between C5 MK2 or Peugeot 508 (I somehow like it more then new C5). PS: As a bonus, photos of my beloved, continental C5 (we will really missed it!): http://www.englishforum.ch/2554231-post1.html

Hi All, I am owner of C5 since March 2014. Probably will soon move to London (from Switzerland, and originally I am from Central Europe). I hope this forum will help me to pick ideal MK2 C5 to avoid any maintenance issues (so sad this great car is getting old).... Have a great day!
