why does my Volkswagen Golf MK7 (2015-2019) make a ticking noise when starting?

Solution

1. Preparation

• Gather tools: socket set, multimeter, wrench set, and safety goggles.
• Ensure the vehicle is parked on a level surface, and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

• Sub-step 1: Remove the positive and negative battery terminals.
• Sub-step 2: Clean the terminals and battery posts with a wire brush to remove corrosion.
• Sub-step 3: Reconnect the terminals securely.

3. Starter Motor Replacement (if faulty)

• Sub-step 1: Locate the starter motor, typically found near the engine’s flywheel.
• Sub-step 2: Disconnect electrical connections from the starter motor.
• Sub-step 3: Remove the mounting bolts using the socket set.
• Sub-step 4: Carefully extract the starter motor from its housing.
• Sub-step 5: Install the new starter motor in reverse order, tightening bolts to manufacturer specifications (usually around 20-30 Nm).

4. Electrical Connections Check

• Sub-step 1: Inspect wiring harness for fraying or damage.
• Sub-step 2: Repair or replace any damaged wires.
• Sub-step 3: Ensure all connections to the starter and battery are clean and tight.

5. Oil Level Check

• Sub-step 1: Remove the oil dipstick and wipe it clean.
• Sub-step 2: Reinsert the dipstick and remove it again to check the oil level.
• Sub-step 3: If low, add the correct oil type (usually 5W-30) until it reaches the proper level.
