Why is the fault light on in Volkswagen Sagitar?

[HectorMarie]

Sagitar engine fault light is on due to: poor quality gasoline that does not meet standards; oxygen sensor failure; air flow sensor failure. The following is an introduction about Sagitar: 1. Introduction: Sagitar is a joint venture A+ class sedan brand under FAW-Volkswagen. The car was introduced to the Chinese market on April 9, 2006. Its predecessor was the fifth-generation Volkswagen Jetta sedan, positioned as a "German high-performance sedan". 2. Exterior: The most eye-catching feature at the rear is the two taillights. The Sagitar series adopts more expensive but longer-lasting LED taillights, which have stronger light penetration and are more conspicuous, providing better warning at night. 3. Naming: The name Sagitar follows a similar naming convention to Volkswagen's top luxury product, Phaeton. Its Latin name, Sagitar, refers to the "Sagittarius" constellation in Greek mythology.
