I’m hoping you can help me, I’m at a dead end and no end in sight!

Recently forked out for two new garret turbos on my D4 XS 3L V6 2010. This was due to indie finding considerable amount of oil and decided to replace. Prior to this inlet manifolds were replaced, EGR pipe and also cross over pipe whilst the body was off.

I picked up the car and still when accelerating over 2800RPM the vehicle is going into restricted performance. I have been told that there are no leaks on the smoke test, crossover valve replaced and electrical solenoid that controls the valve all replaced/tested.

Latest diagnostics (I’m waiting for him to confirm code) is that there is a vacuum issue and no vacuum getting to the solenoid.

It appears someone has messed around with the vacuum lines before, so I’m looking for a diagram to tidy them up again and also any suggestions to remedies that might solve the no vacuum.

Go easy on me, land rovers are new to me but willing to learn and attempt to rectify issues.

is the DPF blocked ? in the handbook for the D3 it says run the engine for about 20 min at abve 2500 rpm to burn it clean i dont know what the D4 hanbook sugests but if you have one look under DPF or diesel particle filter

Picture of vacuum system from sdv6 if its any help, trace from vacuum pump, visibly for a start check hose from solenoid at front to cross over valve, runs across radiator, engine mounts also part of system, check for oil effected gummy pipes, hand vacuum pump is most useful
Just bought a sdv6 with vacuum issues amongst others, on reassembly will go through it piece at a time, I'm far from fully understanding it at the moment but getting there, all the best

Thanks buddy, let me know how you get on. I’ll keep you updated. My vac lines seem to be all over the place as though someone has messed with them before! Only had it since Jan and it’s never been right.
