hey team ,i recently took the egr off my 2.5turbo an cleaned it , the truck runs better an the engine check light has gone ,buts the egr clicks like crazy when i shut the engine down , when i cleaned the egr i was unsure about checking the butterfly in the egr should it move freely ? it moved but not freely an i was unsure about forcing the issue due to the solinoid an was worried about damaging that bit ,? any advice cheers
