[Engine] The turbo issue

[WeeTam]

Hi

I have been reading another thread on here about issues with blown turbos and I am hoping someone can help with my query.

This is a copy of the relevant posts from different users on another thread that describes my query -

"Hi there all I am new here and I have 15 years Citroen experiance so I would love to help you all.
All DV6 (1.6hdi) engine turbo failures I have seen have been caused by injector carbon leakage due to the injector bolts being loose, Not sure why they come loose possible heat cycles of the copper washers not sure. Anyway if you have a DV6 engine check your injector securing bolts tomorrow I guarantee you they will be loose. I have done best part of 40 turbos on these engines and to all my customers I recommend a full engine strip down and clean because the carbon (looks like coal) leaks from the combustion chamber up the injector tube and destroys the little seal between the cylinder head and the cam housing, It then goes down into the engine just where the valve springs are which smash it up and mix it with the oil. It then makes a real mess of the oil and blocks the stupid little filter on the turbo feed pipe on the banjo and starves the turbo of oil and "goodbye turbo." 

"I was chatting to the tech bloke who did my service today.
He seemed to know what I was referring to before I said it.
It seems the long and short of it is ,like polar suggests,the penny has dropped and is signified by the different fastener types pictured by Pigeonpost/drazen and myself.
He says for the latter type its no longer a worry but for the early ones keep an eye out for the blackness/moisture
Leaking will also be audible over the normal engine noise."

I am assuming this would apply to my 64 plate Berlingo 1.6HDi and I was also wondering if anyone knows from what date as per the second post "the latter type it is no longer an issue?

Or should I be checking this out?

Any help would be greatly appreciated.

I think they fitted updated injector clamps / bolts from 2012-13 onwards but maybe Polar could confirm when he first saw the revised ones on an HDi. Mine is a 2012 so I was going to check too, until I read his comment on an old thread that they seemed to have had the penny drop.
