why is my Volkswagen Golf MK7 (2015-2019) making a grinding noise

Solution

1. Preparation

• Tools Required: Socket set, jack stands, torque wrench, OBD-II scanner.
• Ensure the vehicle is on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Components (if applicable)

• Sub-steps:
  1. Remove the wheel using a socket set.
  2. Inspect brake pads for wear; if less than 3mm thick, replace them.
  3. Check brake rotors for grooves or damage; replace if necessary.
  4. Reassemble components, ensuring all bolts are torqued to the manufacturer’s specifications (usually around 78-95 Nm for caliper bolts on the Golf MK7).
  5. Reinstall the wheel and lower the vehicle.

3. Drivetrain Inspection and Repair (if applicable)

• Sub-steps:
  1. Inspect CV joints and axles for any signs of damage or wear.
  2. If CV boots are torn, replace them and add new grease.
  3. Check the transmission fluid; if it is low or dirty, drain and replace with VW-approved fluid (usually VW G 052 162 A2).
  4. Reinstall any protective covers or shields removed during inspection.

4. Final Assembly and Testing

• Sub-steps:
  1. Reconnect the battery.
  2. Start the vehicle and listen for any grinding noises.
  3. Test drive the vehicle to ensure that the problem has been resolved.
