I recommend blanking of the opening in front of the EGR valve.
It is not recommended to cap only at the outlet manifold in engines of the VAG consortium.
It may cause filling of the tube connecting the outlet manifold with the EGR valve with a slurry
of water and oil (the EGR valve shall still work and during opening cause penetration of oil
particulates from the crankcase breather tube).
