Thanks Tony. My Betooll kit does have a separate set-up for CIS testing and I’ll take a look at it when I get home later today. Last night I search around for the Porsche special tool P378 mentioned in the Bentley’s Manual and came across the M12x1.5 dimensions you just mentioned. From Amazon, I then ordered several different adapters having M12x1.5 female threads at one end and varying sized NPT male threads on other hand. This morning, I started to have doubts about the usefulness of those adapters. Thanks again
