    Default C4 won't Start - Big $$$?

    Hi,

    My sister in laws '08 C4 refused to start last week and after no luck with RACV, had it towed to a local Citroen specialist.

    His report was that oil or some such had travelled up the wiring to the fuse box, of which I have heard of before with other Cits.

    The claimed culprit was said to be most likely a leaking power steering pump, needing replacement along with a new fuse box - all up likely to be over $3000!

    Naturally she's pretty depressed about it.

    This sounds pretty excessive and I don't recall her car ever leaving spots in her driveway. Does this diagnosis sound reasonable?

    thanks,
    Leith

    It's steep, if the technician did not charge for diagnosis he is seeking to recoup some costs in the actual work.

    Those elec/hydraulic pumps are expensive+oil+psf1+genuine prices. Its on the high side, but I don't think you will find it to be that much cheaper unless you use second hand parts. IMO second hand elec/hydraulic pumps are a false economy, plus wreckers charge an arm and a leg for them.

    I didn't realize it had an electrical pump. Sadly I can see it turning her off Citroens. Bit nasty for a relatively new low kay car.

    Look for used parts if price is a concern, there is a lot of interchangeability.

    Steering pumps only need configuring if not from an identical vehicle. Not too involved.

    If she turns off Cits, she had better be careful elsewhere - these pumps are from Koyo Seiko (think Toyota) and are widely used in one form or other.

    I believe it's a case of the later the pump the better the sealing. It seems surprising that the pump didn't stop operating due to its own electronics being drowned before it leaked into the harness. Coolant leakage into the engine harness from the temp sensor is another gotcha on some models. It's also worth noting that the engine slave/fuse/relay box can sometimes fail of it's own accord and induce a no start problem, so it could be coincidental that the leakage was found. What other connected parts are also contaminated? Does the work suggested include a harness change?

    I guess one approach for those not willing or able to spend the money would be to pull the seal out of the plug at the pump to reduce the chance of a repeat and remove as much oil as possible from all affected parts using contact cleaner. Some units are well sealed, so that could be quite difficult. It's obviously not the ideal approach though.

    I might the mechanic a call myself, it sounded like he wasn't sure it was the pump. It think she said he had cleaned the harness, but I'm I'd need to clarify that.

    Very common faults for both C4 and C5 models.

    Second hand fuse box will fix the cost of a new unit and my peugeot mechanic tells me there are rebuild kits for the steering box.

    My underbonnet fuse box was swapped out @ 70K still inside extended warranty $2000 to insurer.

    Stay with the Cits I say

    I'd just clean it all and seal the harness so it can't get "oiled up". I can live with some weepage from any mechanical item. It's obviously not pouring vast amounts of oil out to the point where it's draining it's tiny reseviour capacity in a short time.

    Think of it as rust prevention for the underbonnet area. Any hydraulic car owner can appreciate this.

    I had oil travel up a wire by capillary action and flood the computer in a Renault 19 auto (ugh you say). No problem as oil doesn't conduct electricity I guess. Oil drip difficult to locate until computer box opened. A common fault according to Dave K.

    I really am lazy... I'd clean everything .... especially the end with the oil weeps, and seal up the wire with some sikaflex urethane so the oil can't get under the insulation of the wires.

    Spending that sort of $$$ for a minor bit of weeping oil is insanity as far as I'm concerned (yes I'm a huge tightarse).

    How much are the fuseboxes here? On UK ebay only seem to be a couple of hundred dollars.

    New isn't too bad. Price varies a little but the exact one can be found by VIN. Don't think any are over $700, fitting takes ten minutes.
