Restricted performance is cutting in every time I accelerate hard (beyond about 3,500 rpm). It re boots on switching off but always reoccurs. No obvious air leaks on boost hoses/intercooler etc, and 4 codes are showing:
P008 MAF A
P0235 turbo boost sensor A
P22D2 Turbo inlet valve stuck open
P22CF turbine inlet valve mech fail
Local independent diagnosed offside turbo actuator.
Anyone else had the same set of codes, and did an actuator replacement on the right hand side fix it. Be good to know if the 'A' codes definitely relate to the offside turbo? Thanks

 

Head on over to the English XF site at jaginfo.org and search under "restricted" and you will find heaps of threads about restricted performance and secondary turbo faults on the 3.0D, including this one: 3.0D Secondary turbo bypass shutoff valve.
