The engine management light comes on when driving , and seems like the turbo stops working as there is a slight reduction in power. When I switch engine off and back on, the light stays out and the van runs as normal for 20-30 mins and then comes on again.
Thanks, for any help offered

your best bet would be to get it plugged into a code reader and wouldnt have to guess what your fault is
