general problems of the 2003 Volkswagen GTI

Complainant owns a 2003 Volkswagen Gti 1. 8t. Driving home three days ago, check engine light comes on and car starts to stagger and putter. Weird clicking noise. Parked car immediately, ran diag got code p0103 which indicates cylinder misfire. Checked internet and came up with many many other complaining of the same problem and stating that it is a know problem with this model of vw. Called mechanic, he confirmed. Car delivered to mechanic who reconfirmed. Paid $500 for repair. If this is a known problem, why does vw not recall?.
