my Volkswagen Golf MK7.5 (2020-Present) won't start just clicks what to do

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is in a safe and stable position (parked on a level surface).
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Check and Replacement

1. Check Battery Condition:
   • Use a multimeter to measure the battery voltage. If below 12.4 volts, recharge or replace the battery.
2. Clean Battery Terminals:
   • Remove the battery terminals (negative first, then positive) and clean any corrosion using a wire brush.
3. Replace Battery (if necessary):
   • Remove the old battery and install a new one, ensuring the correct orientation (positive to positive, negative to negative).
   • Torque the battery terminals to manufacturer’s specifications (usually around 8-10 Nm).

3. Starter Motor Inspection

1. Locate the Starter Motor:
   • Refer to the owner’s manual for exact location; typically found near the engine block.
2. Test Starter Functionality:
   • Use a multimeter to check for power at the starter motor while someone turns the ignition key to the start position.
   • If no power is present, the issue may lie in the ignition switch or wiring.
3. Replace Starter Motor (if necessary):
   • Disconnect wiring harness from the starter.
   • Remove the starter bolts using a socket set.
   • Install the new starter and torque bolts to manufacturer’s specifications.
   • Reconnect wiring harness.
