I have an 01 Jetta and have had the emissions light come on many times since
35K. Car also ran rough on startup. Took it to the dealer and each time they
said the car was ok and turned out the light. 2 weeks later the light was back
on and the car ran rough again. Finally took it to a dealer who replaced mass
air unit and the light went out. 2 weeks later the light is back on, running
rough, I take it back to the dealer and he tells me 10 bad hits on the engine
came back from the computer check. He thinks he needs a full day to study the
problem. Anyone know what's going on?

Yes leave it at the dealer for a few days so they can look at the issue
closer. If it's a cold start up then they need it COLD. If not they need to
know when the issue happens so they may duplicate it.

They should be able to produce a print out. I thought that when my car
was looked at they printed out something and then handed the tool to
another tech.

If it takes two weeks to reappear then how do you expect them to magically
come up with a instant fix? The "printout" from their test gear tells them
what the computer "thinks" is wrong. What if you have a flakey connector
some where. The thing here is they are trying to find the cause.
