hi all,

i have a mk5 golf 2.0l tdi bkd engine and when im driving down the motoway around 3000 rpm if i let the revs drop it cuts out and i cant start it again but it will start with easy start, i also have no faults codes. i changed both tandem and lift pump, fuel filter, and partially blanked the egr valve ae that was giving me a judder around 1500rpm ( dont know if they are related to the cutting out) , any advice would be appreciative
