Update: LR suggest they cleaned the inlet pipe to the turbo, took it out for a test drive and there is now more oil in the turbo inlet pipe. No idea if that means anything but I know its losing oil - He says its defo the turbo....

Apparently there was a design change fitted from late 2014 models. Twin tubes was it.?

I think they mean the oil drain mod possibly. |

When I first purchased my L322 4.4 tdv8, I had the same restricted performance issue when exceeding 2400 rpm. Having replaced all relevant inlet hoses, and checked that the CSOV valve operated ok, I came to the conclusion that it must be a problem with turbine shut off valve on the left hand turbo ,because no matter how hard I pushed the engine, the left exhaust front pipe was still cold.

Sadly Graeme, this is typical of the motor trade in this country. Sure, there is the odd garage with a proper, experienced diagnostic technician that knows what he's doing, but you have to bear in mind that most are just a 'fitter' (remove/replace). Most competent driveway DIYers are not that far off the typical fitter in a workshop, except they're not chasing bonus to put bread on the table. The OP is at their mercy as he is unable/unwilling to have a go and that is the unfortunate aspect. I like the sound of Dtech's idea, personally. 2012 Vogue TDV8 in Aintree green over sand |

That all looks a bit suspect, I know what I would do and that's have a nice drive to see Craig at Cam Tech, you will get an excellent service and a fair price.... Pete

Yes, it's a situation. In the perfect world, 3 garages would diagnose the same issue, correctly and accurately.

Ash, just undo your filter and have a look at the drain back valve, if only for my sanity.
