Good evening fellow transitiers new to the forum I own 2013 mk7 82000miles at present love the van but as seen in other posts have generated good old diesel knock had new filter may this year only down 4000 miles since change changed suction control valve fuel rail pressure sensor done leak of test all injectors seem good no excessive flows back through return line only issue have found well think it’s a issue as the return line from the injectors is under positive flow when done leak of had quite a flow coming back on the return line. The van even tho ticks over a treat runs quite at tick over fuel knock starts around 1500rpm on through-rev range but van pulls like a train tho just the knocking any help would be gratefully appreciated thanks in advance
