I got a 2002 1.8T Passat. Got only about 6000 miles on it. The engine light started to come on couple weeks ago. I was going to take it to a dealership; however, without doing anything at all, on the way to the shop it went away. I thought it might just be bad gasoline or I didn't tighten the cap good enough??? Then not for long after that, it's back again this afternoon. It ran rough for couple minutes when I started the engine before the light went on. Wondering if anyone has the same problem I have and if this a known issue for Passat 1.8T engine??
