Go to Audiworld, the Original S-car forums, and look at the FAQ. It's
got a nice section on ignition troubleshooting.

Seems likely a coil. From your description, at least.

Well, there are two schools of thought:
1.) OEM is the best. And, if the miles gotten out of the stuff is
any indication, I'll guess that's probably true.
2.) The coil kit is a good low-cost solution for those folks making
RS2 power and lower. DO NOT use 034's. They have a weird failure
mode after 2-5k miles. Apikol, if you don't want to build your own.
While the components for this set up don't last as long as the OEM
stuff, they are cheap, available everywhere and very easy to replace.
I think the 1.8T coil kit is a very viable solution for those folks
who aren't racing their cars, or trying to make super-big power. But
the robustness of the stock stuff is really hard to beat, even at the
Remember, too, that the V6 POS is a direct replacement for our stuff,
at a fraction of the price.
