Can anyone help . I have a 3.0 CDTI Vectra 04.
Put you foot on throttle restricted resonce, let foot up put down again and away it goes no problem.
When it cruises at about 1500rpm it gets a hesitation but if you accelerate it stops.
When cold car ticks over ok on tickover when warm EML comes on code PO105 Pressure Boost Sensor.
Have replaced EGR, Flywheel , And Pressure Boost Sensor.
