[Biturbos4] Check engine light

I've noticed over the last few months that when I start driving the car 
from a cold start and accelerate quickly, my check engine light turns on. 
I've checked with a mechanic who ran the VAG and said this was a piston 
mis-fire.  After four or five restarts, the light seems to go away.

Now that it's gotten colder hear in the North East, I seem to see this 
problem more and more.

The car is a '01 S4, and has 89K miles on it.  Could this be a sign of the 
timing belt starting to go?

Thanks in advance.
