I’ve had an on going issue for the last year or so where my 3.0l V6 Vito goes into limp mode when applying heavy acceleration.

It drives fine without any issues when not pushing it. But the moment I press down hard it triggers limp mode. I can stop and turn the engine off and on again and it’s cleared until next time. No EML either.

I did once manage to get the EML on and had a reading of Back pressure exceeded.

I’ve been researching and hunting down for months a fix for the issue. I’ve taken off the turbo actuator arm for a clean, after reading this being a possibility for the issue.


Any help would be amazing and greatly appreciated!
 
Needs codes reading, there should be historic codes in the ECU.
But the turbo actuator is a likely suspect imho.
