The citroen C5 i have needs turbo to be replaced. The engine is 2.0 HDI 165 and VIN confirms it has the RHH engine with 2010 as year of manufacture. My mechanic has tried to get the turbine capsule so he can rebuild turbo, but so far without success. i have found 2 car wreckers with turbos for sale but in each case they advise their turbos wont fit my vehicle even though the VINs they quote are for exactly same engine as mine with critical RHH. The only difference is that the 10th digit in wreckers turbos show respectively B and D, meaning 2011 and 2014 build, whereas my VIN shows A, meaning 2010 build.
My question is: Can i install a turbo fitted to a 2011 or 2014 C5 with RHH 2.0 HDI 165 engine to a 2010 C5 engine or do the wreckers know that the turbo design changed from year to year? My guess is the 2 turbos I have identified would fit. I would appreciate any advice please.
For clarification here are the 3 incomplete VINs: My car -VF7RW RHH AAL 2011C5 VF7RW RHH ABL 2014C5 VF7RD RHH ADL
 
Could you not ask the service dept of a Citroen dealer if it would fit? In Perth, for example, there is an independent garage, Eurocare, which specialises in continental cars. I have always found them helpful. There must be similar places wherever it is that you live. Or try asking Citroen (Inchcape?) direct. They'll have all the details.
 
It seems it will be because the outlet connection on the turbo changed around 6/11 and so did the part numbers. However, the parts catalogue notes that the outlet air pipe also changed with certain versions of the turbo. If you take the used turbo with the outlet air pipe that was connected to it in the donor vehicle, I'd be thinking those later turbos would fit your earlier model.
There should be aftermarket options for a new unit. You could ask EAI.
How has yours failed? Is it not varying the boost? It's a long job to replace and there are some sundry parts also needed, so be really sure it is faulty. Are you certain it's not a vacuum fault or suspect control electrovalve?
 
I support what David said. The vacuum controls the turbo actuation via the electro valves at the back of the engine. There are 3 of them controlling various functions. I re plumbed mine using flexible vacuum tubing and connectors. Very successful job.
Whilst fitting the tubes I found that one of the original vacuum pipes had been dislodged from one of the electro valves meaning none of the valves were working therefore no turbo boost.
I have now completed 100,000km with this mod. Just be cautious of mechanics diagnosis. I found the original dealer new NOTHING about Euro cars.
 
This shows how the RHH turbo is controlled. The solenoid valves (electrovannes), operated by computer signal, exhaust vacuum in the lines to operate the turbo, The plastic head cover incorporates a vacuum "store" at the back, next to the solenoids.

I have the same car and down the track may have to do the same job.

How accessible were these parts? I would have thought that anything behind the engine is in ´´there be dragons´´ territory.

Thankyou very much for all members who replied. Allen, yes , to be sure i need to ask Citroen here in Adelaide and they are Jarvis Ford. David S, your mention of a parts change in 6/11 means I could not be confident that a turbo from a vehicle built later than mine could be problematic unless some supplementary parts were also obtained. Seasink, thanks for diagram showing how turbo is controlled. Finally, Dijon 16 this is a big job and requires removal of engine if turbo needs to be replaced. The turbo is low down and close to firewall and not possible to remove with engine in situ. In my case turbo had failed with either bearing or seal failure resulting in an oil mist circulating through whole intake system. 4 rubber pipes were soaked in oil and 3 replaced. Once again thanks for all your comments.
 
Subframe out with the engine and gearbox supported will be a faster job than engine out, but still a long job.
If it otherwise works OK, maybe the drain (pipe #5 below) is partly obstructed and the oil being fed to it for lubrication is then misting into the intake? Your C5 originally came with turbo 0375P2, but it has a replacement part# 96 770 627 80 as used in slightly later models from RP 12624=6/11 to 12774=end 10/11. After that it is a different part#, but the same type of turbo. Note A is why you want the outlet pipe with it.

David S, thanks for all that detailed info. For better or worse my mechanic removed engine and i am glad he did, because oil spray had coated steering rack and other parts of engine bay. He showed me all the oil sludge that had accumulated over a considerable time on the intake side and cleaning this out properly was much more easily done with engine out. He told me he could obtain a turbine capsule and reassemble turbo but the part had a pin and hole that did not align with original. Unfortunately I have not been able to see for myself what he is specifically talking about and to complicate matters he's just got covid. I had thought getting a low km turbo from a wrecker would solve the problem but that approach seems fraught. I did see a 2011 turbo but there is no way of knowing if it was before or after 6/11. i am almost tempted to buy it for $595 as it has only done 19,000km and risk it, Now that I have done a bit more looking it does seem the turbine part could be satisfactorily rebuilt with new bearings and seals but in reality that may not be practical..
 
Call Volks Torque with vin on Tuesday and they will be able to supply the correct turbo - located in Lonsdale
