If you are not getting a CEL then you are likely okay for a while.

These coils are sensitive to extreme temperatures and the insulation and weathering will cause them ti crack and then you usu sally get misfires. They an be taken off one at a time and measured for resistance - when you one (or more that has cracks or much different resistance then they should be changed out.

1. Check all connectors for secure fastening and corrosion.

2. Look for cracks or carbon tracking (which indicates a crack and short).

With a multimeter...

3. Check spark plug connectors. Resistance: approx. 2 kΩ

4. Check ignition coil(s). Resistance between terminals 1 and 15 at 20 °C: 0.3 - 0.7 Ω

I also replaced my original .05 revision ('06CTTS) coils (2 occasional misfires) less than 2yrs ago with new .09 coils & plugs, granted I had the new .09 coils for 6 months but two new revisions (.20 and now .21) since then? Can't they seem to get them right or are they actually making them better?

I know Audi & VW (VAG) have had coil problems in the past but I they have went through 2 or 3 revisions with some models, not even close to this many.
