My issue is definitely a bad coil.  Moved the coils around, and the
problem followed the coil.  Measuring block 15 in the VAG-COM.  Buying
the VAG-COM tool just saved me a ton of money!  Couldn't have figured
this out without it.

Maybe this is already in the collective wisdon, but I didn't know it..
 So here it is so that it may help someone else:  Symptoms were
flashing MIL, really rough running.  Misfires on a single cylinder at
idle.  Misfires would get a bit better when revved up, but the car was
barely drivable.

Also, I have the L version on all 4 cylinders.  As far as I know, the
coils are all original.  Should I replace all the coils, or just the
bad one?
