hello! can anyone help i have a vibration at 1600 rpm then it goes only does it under light throttle maybe a heat sheild i was thinking? does it in the first three gears more. just a bit annoying! thanks.

sounds as if its coming from the back of the engine? near the turbo?? can hear it in the car.

Try wedging a bit of foam or two around the area of the air box. That tracked it down on my old PD105.

thanks i will try this tonight.
