Think it is same for mk1 and mk2 - see table below.

After looking up the issue extensively online I have found that:

  • A lot of them have stage 1 and 2
  • Up until 3 Porsche will maintain warranty and allow to extend it - as from 4 only after a thorough check-up
  • 1 ignitions equals about 0.002sec

 

Following reason could be why stage 1 occurs quite often:

Stage 1's are actually a more-than-passing probability.

One doesn't need a moneyshift to log Stage 1's. It happens in hurried upshifts. As one transitions between WOT and clutch down, letting out the clutch too early will "unload" the engine and allow it to spin ever-so-slightly above the rev limiter. Nothing serious as we all know, but that's how the occasional Range 1 shows up even for cars properly driven.
