Vito 111 CDi 11/2008
Hi Guys
Can any body help me please
Vito 111 cdi 2008/2009 model with electronic turbo actuator and vvturbo. Actuator appears to be work ing and moves freely when standing and reving engine from idle.
The dealer tells me it needs a new turbo but I have had it off and the variable vanes are fine and running free. now re fitted but still problem with limp mode. When cold it appears fine but as soon as its warm it will not rev beyond 3000 rpm and some times make a horrible noise resembling pinking. Its almost as if the valve timing is out. The noise comes and goes but it will not clear from the limp mode. Any help appreciated, Elnno.

probably is turbo

The housing distorts when hot and causes the collar that alters the veins to stick.
