What causes gearbox jerking in the Audi Q4L?
1 Answers
Audi Q4L gearbox jerking is caused by damage to the valve body or solenoid valve in the transmission. Below are the detailed explanations: 1. Valve body damage: The primary reason is often a dirty valve body, which can degrade the quality and frictional properties of the transmission fluid. This increases friction and wear, while sludge buildup in the transmission can lead to blockages in the valve body and pipelines, disrupting proper oil pressure regulation and resulting in gearbox jerking. 2. Solenoid valve damage: Damaged solenoid valves are another major cause of jerking. If the Audi A4L exhibits jerking during acceleration, first check whether the engine mounts are damaged. It could also indicate clutch slippage in the transmission. Inspect the transmission for any burnt smell or excessive dirt, and replace the transmission fluid if necessary.
