Originally VW used these green labeled coils (part number 00061) from 85 to 87, switched to a different one for 88 and 89 (grey label - part number 00074), and then went back to the green label ones for 90 and 91. In subsequent years they issued a service bulletin that when the grey label ones needed to be replaced, to replace them with the green label versions. As such we stick with this coil as the one to use in all models from 85 to 91.
