armchair mechanics, here's your chance to strut your stuff. my wild-donkey-guess is that somehow the timing is way off.
my 06 jetta 5-spd runs fine once started but has such difficulty with hot-starts that i've parked it, awaiting dealer-visit next week.
also it makes a heavy single-knock/rap on many cold-starts. that can't be good for the engine.
37k miles now. the issues started after my return commute from san jose -> boston. i did park it on top of a sprinkler head and it got watered from underneath for a few minutes, maybe that is a factor. ? doubtful. also:
right before the boston<->SJ commute, dealer swapped the fuel filter - it was clogged after 18k miles, and a fuel stop at a station that i realize in hindsight had old/crappy fuel. (500 ppm).
there it is.
