my Volkswagen Golf MK7.5 (2020-Present) won't go into reverse what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the vehicle to cool down if it has been running.

2. Check Transmission Fluid

• Remove the transmission dipstick (if applicable) or access the fill plug.
• Wipe the dipstick clean, reinsert, and check the fluid level.
• If low, add the appropriate type of transmission fluid (refer to owner's manual for specifications).

3. Inspect Gear Shifter Linkage

• Locate the gear shifter assembly.
• Inspect the linkage for any signs of wear or disconnection.
• If damaged, replace the shifter linkage components.

4. Scan for Error Codes

• Use an OBD-II scanner to check for any transmission-related error codes.
• If codes are present, refer to the service manual for specific troubleshooting based on the code.

5. Examine Clutch Operation (Manual Transmission)

• Depress the clutch pedal and check for any unusual resistance or noise.
• If the clutch is not disengaging properly, inspect the clutch master/slave cylinder for leaks or failure.
• Replace any faulty components.

6. Test Brake Light Switch

• Locate the brake light switch, usually mounted near the brake pedal.
• Check for proper operation by pressing the brake pedal and ensuring the brake lights illuminate.
• If defective, replace the brake light switch.
