“2001 Audi A4 quattro 2.8l. As driving smoke was coming from hood.. Park and realize the engine was on fire. It look like it started by the passenger side headlight and spread. I read that Audi had a recall on head light switch but did not rec, a recall letter. Not exactly sure where the fire started my Audi caught on fire. I dont't have pictures to upload but I will soon. I am very hurt to know that the car I enjoyed driving caught on fire/disappointed with Audi”
