Ive got 203k miles on my 1998 a4 (1.8Tqm) and I've traced my most recent problem to a bad coil. Considering my mileage, should I just replace the coils as a set, or does it matter? This is the first car I've owned with individual coils, and it seems that most owners (yes, I've STFA's) just replace the individual coil, but I've yet to see anyone with the mileage that I've got. Any advice is appreciated...

Are you sure it's a coil and not a POS? Those early coils are very reliable. If you want a used one, I have a few laying around. $25 each.

I pulled the POS and checked it via a method I found online, and it checked bad. Changed it out and haven't had a problem since. Hopefully that's all (for now). Good call on the module! Thanks for the suggestion.
