What Causes a Passat Lingyu to Stall Automatically?
1 Answers
Below are the reasons why a Passat Lingyu may stall automatically: 1. There are many potential causes for stalling, so the first step is to analyze the symptoms of idle stalling. If the engine stalls immediately upon entering idle operation, we refer to this as "no idle." If the engine occasionally stalls at idle but returns to normal after restarting, we call this "intermittent idle stalling." 2. Common causes for the "no idle" malfunction include: damage to the engine idle control valve or its wiring; vacuum tube leakage in the brake vacuum booster; diaphragm damage in the brake vacuum booster; intake manifold air leakage; or issues with the idle control module in the engine electronic control unit (ECU).
