If you find nothing then take a shot at the mass but buy Bosch new not rebuilt they are such problems they are considered a tune up part on a V.W.

Only use Genuine VW or Bosch distributor caps and rotors.
I've been using Bosch FR8LDC in my car for years with good results.
Now running the Bosch +2 Platinums and my MPG jumped from about 21 to 25! A lot of others will tell you not to mess w/ the platinums but they are doing well for me.
I got... bosch platinum plus plugs... and you could feel the difference right away with the new plugs. started faster, idled smoother
A Bosch alternator doesn't care which Bosch pulley it uses, be it a 70A, 90A, 120A or 150A. The shaft is the same 17mm OD for all of them. What matters is that the pulley matches your belt and application.
From what I understand the afterglow on the Duraterms works because they self regulate voltage per each plug, not allowing them to burn out. It virtually eliminated rough idle on the cold start.
I have installed these in my 81 and they work very well. Start it up and let the plugs sit on for an additional 30-45 seconds.. pretty much does away with the rough cold starts.
OK. First thing is the voltage regulator was faulty. It was a new voltage regulator but it wasn't a Bosch part. I switched the 2 regulators and the problem went away.
last year i did the mistake of buying them and they will not fit anf the light is not that good.
