Hi, I have a mk5 tdi 140 BKD, I replaced the EGR valve 8 months ago and it failed 6 months later I replaced it again (europarts refunded me) and today the engine light came on again and sure enough its the same fault again, Flow Insufficient. I took the hose off the egr and i can blow and suck air straight through, so there is no vacuum in the vacuum valve. On a new functioning egr you cannot suck or blow through it. Does anyone know what can make brand new egr's fail so soon..2 units in 8 months.
there are no other fault codes. tia
