...and today I finally understood why... You see, when the pump stops working, it cannot presurize the suspension circuit any longer, but the existing pressure is not lost instantly. This is why, for the remaining couple of miles between where the pump died and my home, the car felt absolutely fine. However, during the night, the system depresurized completely, causing the car to lower and the suspension to feel hard as hell. Anyways, ordered the HP pump unit today, directly from Citroen (after what I have invested so far in their business, they were kind enough to give me a 10% discount on parts, and a 15% on labour) :D It should arrive on Friday, and get installed and set-up on Monday... Now, the only question that remains is: will there be any other collateral damage?!? Should I expect the spheres or struts to have been damaged by the loss of pressure (and me having to drive the car like that to the service shop)?!? Thank you, Sam PS: @Steve, it's funny that you keep your car's temperature in Celsius... I used to keep my Citroens' language set to French (you know cause it's a French car and everything), but I gave that up, because everything just sounds better in English However, I might just get back to it - maybe that will keep my car happier and it won't break down in the future :D |

Finally, tomorrow my brand new pump & connecting pipe will arrive and they'll start working on getting my car back on its wheels Keep you posted on the developments, Sam |

My C6 is firmly in the Celcius reporting camp: warning for ice kicks in at 4 degrees and we all know water freezes at zero. Regards G |

Ha, I didn't know that, my bad... :D My appologies to you all for presuming that you'd use F instead of C Cheers, Sam |

Hey guys, Got news from the service shop today - they took out the old HP pump and confirmed that it was fried, but... ...and there's a big BUT here... - How big? - Oh, about €2,500. That big! ...it seems that when it got fried, it also took the connector on the cable with it, and, that's a cable that runs across the full length of the car connecting various stuff along the way, and it's worth €2,500 as an OE replacement I honestly don't know how I am going to pull this one off, I never felt like crying through my past car troubles with the C6, before, but now, I just don't know... :D Any ideas?!? Thank you, Sammy |

Why can't an auto electrician replace the connector/add cable? Citroen do a cable repair/splicing Tech Doc........ - Click Here - It's got to be far cheaper than replacing a whole harness Sam |

Thank you Dave, That's what they're gonna try to do, but it's only possible if they find a replacement connector... There's gotta be an identical or at least similar connector somewhere on a cheaper part, or something. Fingers crossed Cheerios, Sam |

A long shot but it may be worth giving this a try: - Click Here - Do they know wether the pump siezed first or the motor? |

Hi Sam, post a photo of the connector - not all PSA connectors are proprietary , some are industry connectors available from the aftermarket. I have had pretty good dealings with a UK company called Simtek who sometimes have in stock a large range of recycled connectors. Also how many pins does your connector have? any coax or shielding? | ||

Hey speedfix - I thought of them instantly and I will send them my old pump, maybe it can be reconditioned Hey Dave - thought of that, but unfortunately there are not many beakers yards in Romania and the few ones that do exist have no hydraulic C5 nor a C6 ATM, but I will keep looking There was a front-banged 2.7 HDi Exclusive for sale at about 2500 EUR with everything still on it a couple of months ago, and had I known then what was going to happen, I would have surely given it a more serious thought Hey G - I will go there this evening and take some pictures and possibly even take the old pump home and then I'll post back. Thank you soo much, Sam |

Hey guys, Sorry for updating you later than I've anticipated. Good news is that I found a C6 2.7 HDi some 180 miles from Bucharest, called them and they sent me the cut off connectors that I need. I've included a picture below... In the picture you can see that the grey safety latch on the big connector is broken, but hopefully, I can replace it with the on on my old connector... I also asked George, an experienced Electrical Engineer and good friend of mine, if he might give me a clue as to why this happened - why did my pump and connector burn out, and why didn't the fuse go out?! His explanation was simple, logical and made total sense to me - he told me that the pump didn't burn out and take the connector with it, but in fact it was the other way around - a small short circuit happened inside the connector, most likely caused by moisture or some other form of electricly conducting dust or debris. The short circuit itself was local - big enough to kill the pump, but small enough not to register with the upstream 40A fuse. I asked him if regular maintenance of that connector with an electrical connection spray would be a good idea, in order to prevent this from happening in the future. He was reluctant to give me a thumbs up on my idea. On the one hand, he said that some form of maintenance should definitely be performed, given the serious implications - 1,000€ pump + 2,500€ harness. Something like a light dusting off, spray with canned air to evict moisture, but he would advise against using connection spray because the pins are too close together and, depending on its quality, the connector fluid itself might act as a base for a new short circuit... Bottomline - check you connectors regularly, but be mindful of what products you use for electrical conditioning. Cheers, Sam PS: if you need anything from a C6, shoot and I'll call the guy and see if they have it or not. They had just gotten the car so most of the stuff is still on it (FYI, shipping from Romania to the UK is 20-75€, depending on the package size and weight for packages up to 20lbs., so you can factor that in)... |

Strange opinion, or not the right connector- or connector cleaner spray. First i would like to stress that any connector has to be properly cleaned before opening. Natural behaviour for any engine part, but not for electrical stuff. Then spray it with proper contact oil NOT WD40 or the like. You may use so much that it will squeze out on reassembling. The reasoning behind this is that the spraying the oil in will blow out the dirt that got in anyhow, it will clean the contacts, it will prevent air from forming oxide on the contacts, it will reduce the amount of air in the contact, and so prevention sucking water in on the temperature and baromatric cycle. Proper oil has a higher insulation factor then air, while it dissapates heat better then air. High voltage transformers are filled with oil. Contacts burn because normal currents over a poor contact generate heat on a very small spot. Contact go bad because of dirt, bending, and oxidation. Never try to "clean" connectors by scratching with anything hard. You will remove the very thin gold layer that protects the contacts surface from oxidation. Never wriggle connectors. You will forcible destroy the fine tuning of the springs that prevent bad contacts. |
