I just plugged in another. Do you have an extra? If not, where are you? You could borrow one of my extras. I do have a few known working units. They are the same on quite a few VW/Audi. This went south on my 87 16V Scirocco. I actually used one from a 91 Jetta IIRC.

I'm sure that the Bentley has a way to check.

	How does one test that?


	 


	Also, there was a suggestion to check the
	12v at the coil – coil has 4 wires (2-green on one side, 2 black on the
	other connector) – which ones deliver 12v to the coil? (they look awfully
	thin)


	 




	Vittorio -
