Year of Manufacture *: 2009 Engine Size and Code *: 1.6 HDI
For anyone who potentially gets one of these through there doors, hopefuly this might save you some heartache. (That is unless you don't get involved in the first place !!)
We had this C5 come in last Sept with a failed turbo, we,(I)replaced the turbo along with new oil feed pipe, oil return pipe, oil pick up strainer in the sump, banjo bolts - all supplied genuine from Citroen. Flushed engine and new oil and filter.
Car came back in 2 weeks ago with the turbo failed again. Only thing different this time was that injector 2 had some blow-by.
In the Citroen supplied oil feed pipe there is a very small filter (see pic) that fits inside the lower banjo bolt, apparently you don't fit this - you throw it away, but Citroen failed to tell me when they supplied it ! First cock up !!
Because the injectors sit inside tubes that pass through the cylinder head, when they have combustion gas blow-by the excess heat bakes the oil inside the cylinder head that turns to carbon and drops to the sump and is then carried around the engine. Having heard about a modified oil feed pipe I contacted Sean Savage of Springwell Motors (01924 404366) to see if he could supply me with said new pipe, he didn't have one in stock but he had one made for me in a couple of days.
So, with this new pipe you are able to remove the filter at any time (easily) and monitor any build up of carbon.

More than welcome dave. good pictures. like you i got stung once with these turbo's. Not a cure to these dirty engines but sure as hell gives the turbo a fighting chance. hope you got it sorted with customer.
Is this issue linked to long life servicing, I have several of these pigs on my books but have switched all to fixed interval servicing as soon as they call me, VAG caught a cold with longlife servicing, and not got a single VAG on that daft schedule, all converted to fixed/yearly servicing
These are just dirty engines!! even when all the advised cleaning etc is carried out they for some reason blow new turbo's in literally 1500 miles. 1st one bit me in the ass which is why i made these pipes. didnt realise hyundai and kia use this engine aswell though. great engines i just would never replace a turbo once its gone without this pipe. the main agents around here will not do a turbo replacement unless they have a NEW engine fitted. that speaks volumes itself. sean
Kia/Hyundai don't use this engine. Their issue, is the injectors are mounted inside the rocker cover. Any injector seal blow-by is undetected, and causes carbon build up in the rocker, which subsequently ends up being washed down and blocking the oil strainer in the sump.
