Hi, just got this out of my DG , probably a vw recon unit, Pierburg seems a bit oily just below the plastic cover around the top circular edge of the intake. Engine uses a bit of oil but not too bad. This plug looks like the rest except that the tan/lightish colour is darkest on this none. Generally colour of tips looked ok but quite oily around the circular part as in pic. Any thoughts....that are relevant! Thx
