What does the fault code P035100 mean for the new Jetta?

[CodyAnn]

The fault code P035100 in the new Jetta generally occurs only when the battery is low and belongs to the power system fault code, with abnormal cooling fan behavior. Jetta fault code P336200: Gas operation, misfire detected in cylinder 1 (static fault). Jetta fault code 002E18: Carbon deposits can cause incomplete gasoline combustion, leading to engine shaking issues. Engine carbon deposits have significant impacts on the car: first, they reduce engine power, resulting in uneven and gradually decreasing power output—in other words, the engine becomes weaker. Second, they increase fuel consumption, adding to the economic burden. Third, they make cold starts difficult, meaning the engine is hard to ignite. Finally, severe carbon deposits in the combustion chamber can cause cylinder knocking, produce noise during low-speed acceleration, damage the pistons and crankshaft, and lead to engine overheating, severely affecting car safety. Additionally, they cause excessive emissions, not only failing annual inspections but also directly worsening environmental pollution.
