Default coilpack failed...
This afternoon when I start my 02 A4 2.0cvt, the engine run very rough and the check engine light flashing slowly...later I found out that one of the coilpack was melfunction! I then buy a new one and replace it. (but I drove at 80km/h for around 10km before replacing it). After I changed the bad coilpack, the engine run very smooth (as before) BUT the check engine light stay ON all the time...! I just wonder....is there any other things went wrong or do I needed to reset it using a vag tool after I change the coilpack..!? Thanks for all of your valuable inputs.

Default 80km/h for 10 minutes on 3 cylinders? Wow you must really hate your car.
Always carry a couple of spare coilpacks in the trunk.

The solid CEL will dissapear on its own in a couple of days.

It's recommended, at least carry a spare coilpack regardless.
