When you accelerate to overtake, your Audi puts more power through the driveline, which includes the transmission, driveshaft, and differential. If any of these components are damaged or worn, they can cause the driveline to shudder. Here are a few potential causes of juddering when accelerating:
- Faulty transmission: A faulty transmission can cause the vehicle to judder when changing gears.
- Damaged driveshaft: A damaged driveshaft can cause the vehicle to judder when accelerating or decelerating.
- Worn differential: A worn differential can cause the vehicle to judder when accelerating or turning.
- Engine mounts: Worn or damaged engine mounts can cause the engine to move around excessively when accelerating, causing the vehicle to shudder.
- Driveline alignment: If the driveline is misaligned, it can cause the vehicle to shudder when accelerating or decelerating.
- Low fluid levels: If the transmission or differential is low on fluid, it can cause the components to overheat and start to shudder.
- Damaged vacuum lines: If the vacuum lines are damaged or disconnected, it can cause the transmission to shift erratically, causing the vehicle to shudder.
How to diagnose the problem
The best way to diagnose the problem is to take the vehicle to a mechanic. The mechanic can perform a visual inspection of the driveline components, check the fluid levels, and test the transmission and differential. Once the problem has been diagnosed, the mechanic can then make the necessary repairs.
