Some time ago I bought a E-Tron Duralife ignition module to use as a spare. Upon rebuilding my distributor, I decided to install this new ignition module. Bad idea! I don't think I drove more than 100km before this thing left me stranded on the side of the freeway. In case anybody wants to know, I did use the proper heat sink grease, and one of Dawgs heatsinks as well.
Take a look at the attached picture of the module in question and avoid it like the plague.
