    Default 2011 Citroen C4 Grand Picasso 2.0 HDI High Pressure Fuel Pump Replacement

    My high pressure fuel pump has failed and requires replacement and was wondering whether any one can advise where I can obtain a suitable replacement in Sydney at a reasonable price?

    EAI is the 'go-to' also Continental for experienced impartial advice.

    Welcome to AF by the way, but how did this come about? I expect mine will follow
    (failed to start ...)
    so please let us know how you go.

    water in fuel will do it,any decent diesel shop can get one in. Try EAI or maybe a wrecker on aussiefrogs. They should not fail quickly or easily.

    As said above, high pressure diesel pumps don't give a lot of trouble, but they are expen$ive to replace as a unit. Fixing their internals is the specialty of diesel repairers.

    I am wondering if water hasn't been drained from the filter housing at service, and has gone on to damage the pump. If you feel about under the filter you will find a transparent water drain tube. The bleed screw is in front of the housing at the bottom.

    Make sure that the people doing the diagnosis know what they are doing ,after seeking expert advise and sending to england for a pressure pump for my sons 306 diesel ,i found that the low rail pressure fault registered in the computer was due to the failure of the in tank pump ,is it broken or falling apart or douse it appear to be not producing pressure ,pugs ,i know there is a lot of difference between a 2000 model and 2011 ,all im saying is make absolutely sure that ,everything is checked out before spending your money

    Yes, how was this diagnosed? This model won't have an in-tank pump as the fuel is drawn via vacuum, but it still does have a pickup in the tank/gauge unit that can be partly blocked by globs of Eolys additive. Similarly, a blocked filter or a failed pressure sensor could be at fault. You just want to eliminate the less expensive possibilities first.

    Be careful, my 2004 307 does have an in tank pump, not sure about this car though, easy test is remove fuel line to filter and out key to acc. Did this when I got water and had to replace high pressure pump. They do not like water at all.

    The later 2.0 HDI engines, like the RHH, use suction to lift the fuel. The tank unit has the strainer and gauge sender.

    Looking for water is a trivial exercise - put a glass jar under the transparent drain tube, open the bleed screw at the filter housing bottom, and loosen the air bleed screw on top. Get a reasonable amount, close the screw and remove the jar. Fuel floats on any water drained. Afterwards, give a few squeezes on the priming rubber bulb, tighten the top bleed, and let the engine suck the last bit up on the starter motor. When it is fuelled it will start.

    The sensible time to do this is when changing the filter.

    What type rhr or rhh right on the cut off what injection Siemens or Delphi if itís delphi I would try a suction control valve first unless of course there is metal coming out of the pump then you should be doing injectors cooler and tank pickup and a full flush

    Default The saga cont

    Thanks Guys, The saga began when smoke appeared from the engine bay when my daughter tried to start the car. It is only six years old and (110k on clock). I was told by a mate to replace the battery. So NRMA came out and replaced it with a good battery. I was able to then start the car but it had no power to move. I then got NRMA to check it out at home. The Patrol Man could not diagnose the issue and NRMA ended up towing the car to the NRMA Autoserve in Artarmon. I then received a call to advise they had received a number of codes - but suggested towing it to a European Auto Electrician in Rosebery. However they charged $132 per hour and a minimum charge of 2 hours. After about a week I received a call from NRMA stating that the issue was the High Pressure Fuel Pump. The cost of the part through the distributor in Sydney was really expensive so I did a search on Ebay and found a genuine part for $500 during my initial search. I called up NRMA immediately and the foreman did the same search and found a similar price. I have subsequently found that the part I found on Ebay from the UK was for a 1.6 vehicle where mine is a 2 litre. Of note the Ebay price I found seemed to increase the more times I checked it out for some reason. I also have requested a quote from a wrecker in SA and I am awaiting a quote from him. I have also requested a quote from a supplier in the UK for the part. The local parts guy in Artarmon advised it would take thee weeks for the part to be shipped from France as they don't have the part 1920QH in stock. NRMA have also advised I can get an Aftermarket pump for slightly less than the genuine part and they have it available. I think what I really need is a good independent Mechanic who specialises in Citroens and can obtain parts at a reasonable price in the lower Northshore. It would be appreciated if someone can recommend one.

    Thanks for the advice. How often should you be bleeding the water from the drain tube? As this may be one of the reasons why the high pressure fuel pump failed?

    The VIN indicates your engine. RHH or RHR at positions 6-7-8. Then we will know if it's a Delphi or not.

    Citroen independents on the lower North Shore are PQ Automotive at Chatswood, and Revivemylion from Cremorne who will come to your place. Both have websites.

    Thanks for the advice. I haven't bled the filter housing before.

    Assuming the part# 1920QH is correct, you are looking for a pump that should be common to C4, C5 and C4 Picasso with RHR in the VIN, being the DW10B engine. That shouldn't be too hard to find as a used part. There are a few wreckers around Sydney who would have dismantled suitable donor cars. Riverside Spares, ASV and so on probably. Continental Cars have wrecked at least one older Picasso. In Melbourne, you can try forum sponsor French Connection or BM Spares. Martin bray in SA if you were not dealing with him. The engine was used from approximately 2006 through to 2010/11, so there should be quite a few out there, including some privateers dismantling the odd car via eBay/Gumtree.

    The pump could be faulty, but the smoke would tend to suggest something else may be going on there. Injector leaks are uncommon, but not unknown I would think the names suggested would be OK to diagnose it and repair, locating a good used pump if required. Have a really good look at the air handing hoses for leakage. Also consider the EGR valve may have given up.

    And as I said before if the pump itself has failed ie impellers worn and damaged you would need to replace the injectors etc due to the metal in the system the suction control valve can be replaced separately and thatís what normally fails in all pumps deemed to be stuffed

    The VIN is VF7UARHJHAJ880535 so it is an RHJ. Thanks for the advice Citroen Independents. What are your thoughts about fitting an Aftermarket or reconditioned high pressure fuel pump?

    The delphi pump on my RHR engine has a fuel pressure regulator solenoid that can be replaced separately and can be bought from Delphi agent in WA for less then $200. I had my solenoid replaced recently to stop the HP fuel pump from making loud rattley noises on first application of the throttle. It is nice and quiet again now.

    Cheers, Ken

    RHJ was the version used in the Picasso to replace the RHR when the C5 went to RHH. Very similar, but assigned a different emission code. By VIN, this one is a Siemens pump 1920QH.

    Default Saga continues

    The HP Fuel Pump has been replaced however I have now been advised that the Peddle Sensor needs to be replaced, I have been able to source a replacement part and hopefully the car should be good to go once the replacement part has been fitted.
