Well I  have a lot of faith in scummy black coils - they're pretty reliable,
while  some of the blue coils have been unreliable according to others.   
The
black ones can go bad - easiest thing is to try a new one.  I ran  a blue
coil (genuine German Bosch rather than modern alternative) on a  Beetle, and
always got pips and hollows on the points.  It doesn't  seem to happen with
the black coils.




I noticed this too, when I ran my German blue coil (before it died in  
2004).I haven't noticed it since swapping to the black coil though. Today's blue 
 coils are hit and miss on reliability. I've seen some quit in a little 
over a  year, and some go longer, and some go shorter. It's up to you whether 
or not you  want to buy a new coil, but IF you can borrow one for testing, 
then I'd try  that (as a diagnostic tool). I only say that, because I've only 
had 1 coil fail  in 20 years of driving VW's, so it's not an often happening 
thing. Like I  mentioned above, I got 14 years out of my German blue coil, 
and the black coin  in my wire's T-3 is already 30+ years old.
