as the title says. When driving along if I go down a dip or sudden hill in the road I can feel the power being cut slightly to the engine then back to normal after a second or 2. Anyone know what this might be? It's a commonrail 2.0 tdi dpf. Also it happens just in normal driving after a motorway run. Power just seems to cut in and out slightly while driving steadily along the road. Anyone else get this? Cheers
