What are the reasons for the Audi A6L's lack of power when starting on a slope?

The reasons for the Audi A6L's lack of power when starting on a slope are as follows: 1. Dirty air filter: The air filter is designed to protect the engine and reduce wear, usually requiring replacement every 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed, leading to engine shaking. Simply replacing the filter element can solve the problem. 2. Open circuit in high-voltage line: An open circuit in the high-voltage line refers to a break in the conductor core, which can affect ignition and cause engine shaking. Use a multimeter to measure the resistance and replace the one with significantly higher resistance. 3. Spark plug lifespan: Spark plugs have a limited lifespan. After exceeding 30,000 to 40,000 kilometers, their ignition efficiency noticeably decreases, affecting ignition. This is the most common issue, and replacing all the spark plugs can resolve it.
