about a month ago the doblo 1.9 jtd lost turbo boost. after cleaning out the egr valve of carbon deposits all seemed fine. just recently lost boost again. checked the egr valve, not sooted up, so reassembled, van ran again. two days later the same. just redid the proceedure flooded the valve with wd40. seems ok again.
noticed that after the clean/reassemble the turbo boost was very noticable, nothing until 2000rpm then boost, after a few miles under the clock the boost is softer and less pronounced, just drive more torque below 2k then a boost at 2k.
if i drive just below 2k it stutters a little until the boost happens.
question is, the EGR valve, just wondering if its going to let me down again.
what should the engine feel like? nothing until 2k then boost or the softer delivery? its a 2006 euro4 1.9 8v jtd.
heard some folks blank the egr off, why? postive/negative effects.
help please.

note the egr has electrical cable to solenoid.
