Hey dude love the V10 content, just a quick note from a humble hgv mechanic; get the map checked, it is quite smokey for a v10 TDI with those mods (I have a v10 Phaeton myself) could possibly be down to overfuelling caused by a boost leak or a drippy injector (just remembered you said cyl 7 had a misfire at one point). Anyways, I love the old VW v10s and I'm glad to see someone enjoying it as much as you are! Keep it up, and keep her truckin!!!
