why does my Volkswagen Golf MK7.5 (2020-Present) jerk when I shift gears

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, and a fluid pump.
• Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Check and Replace Transmission Fluid

• Fluid Level Check:

  • Locate the transmission dipstick or fill plug.
  • Remove the dipstick or fill plug and check the fluid level. Add fluid if low.

• Fluid Replacement (if needed):

  • Drain the old transmission fluid into a suitable container by removing the drain plug.
  • Use a fluid pump to refill the transmission with the manufacturer-recommended fluid type.
  • Replace the drain plug and torque to the manufacturer specifications (typically around 25 Nm).

3. Inspect and Replace Engine Mounts (if necessary)

• Remove Components:

  • If applicable, remove any components obstructing access to the engine mounts (e.g., air intake).

• Mount Inspection:

  • Visually inspect engine mounts for cracks, tears, or excessive wear.

• Replace Mounts:

  • If damaged, unbolt the engine mount from the frame and engine (typically requires a socket set).
  • Install new engine mounts, securing them to the specified torque settings.

4. Inspect Clutch or DSG System

• For Manual Transmission:

  • Check the clutch fluid level and condition; top up or replace if contaminated.
  • Inspect the clutch pedal for proper operation and free play.

• For DSG Transmission:

  • Scan for faults in the mechatronic unit; if faults are present, consider recalibrating or replacing the mechatronic unit.
