Hi, I'm having some difficulties trying to figure out, wich oilpressure\indicators I have to use in my tdi engine, the oil lamp is lighting up in the speedo, and so far I've found out, it's one of the two indicators that dosent work, but I don't know which bar\color goes where.. in the head and the block? How many BAR should they go to, and what color do they eventually have? I belive the one in the head is gray, and the one in the block is black.. but I also need to know the bar's :\
