What causes an Audi A6L to roll back on a slope?

[LaBrianna]

The reason for rolling back is that the clutch contact point is not lifted enough (the clutch is lifted too low), or the handbrake is released without giving enough throttle (the car's idle speed is too low to start the vehicle). Introduction to the Audi A6L: The Audi A6L is the first Audi model to enter the Chinese market, with its predecessor being the third-generation Audi 100 (code-named C3) introduced in 1988. The Audi A6L is a vehicle series developed by FAW-Volkswagen Audi based on the German new A6 and serves as the successor to the A6. Power of the Audi A6L: The new A6L offers a choice of high and low power 2.0T inline four-cylinder engines and a 3.0T V6 engine. The 2.0T models are equipped with a 12V mild hybrid system, with the 40TFSI model delivering a maximum power of 140 kW (190 PS) and a peak torque of 320 N·m.
