probably right on both, his red light was an immediate disqualification, you didn't know this, but I wouldn't worry about this, you have what 2 practice runs before competition starts, that's not a lot, if your really serious about your times you'd be out there on a trial(non-comp nites).
this next part is more important, I wouldn't worry about it much, as I wouldn't get caught up in dragging your TD, dragging and german cars don't go together normally, unless you have overhead or deep pockets, you drag once in a while, cool, if you have overhead you've built a power train, if you have deep pockets your willing to pay repair bill. i'd definetly go pretty easy on the clutch, and gear box, unless you have deeppockets, you don't, I know this. too much racing of these motors and you'll be dropping parts on the track.
real good story, you did real good! .01 break out good 1.
keep the car and story, not just the stories and the resulting break down that ensues.
I dragged my tdi 1 time. porsches are a nono for dragging too fyi.
I've said before you go rather easy on these cars and they last A Long time...like my 1 would turn a million in not too long (apx 800k-850k on no longer working clock, clock stopped short of 700k). i'll never drive it again, I don't think, not the biggest loss.!.
