On the way to Vegas this morning the "Emissions Workshop" light came on again on the Passat. Over the next few dozen miles the "check engine light" flashed on and off, mileage was poor and the engine ran rough. The first debate is where to take it to get work done. Last time it went to a shop other than the dealer they couldn't read the code on the computer as Volkswagen keeps them shrouded in secret-decoder ring fashion. Deciding the least of all evils was the dealer I called to make the appointment hoping they could get it in this week. Findlay Volkswagen went one better and got it in and out today. One two coils later they have called to say it's ready to pick up.
