my Volkswagen Golf MK7.5 (2020-Present) has a rough start in the morning what’s wrong

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the engine is cool before starting work.

2. Inspect and Replace Spark Plugs

• Remove the engine cover if applicable.
• Use a socket wrench to remove spark plug wires and then the spark plugs.
• Inspect the spark plugs for wear, carbon buildup, or damage; replace if necessary.
• Install new spark plugs with the recommended torque (typically around 15 lb-ft).
• Reattach spark plug wires securely.

3. Test and Replace Ignition Coils (if necessary)

• Disconnect the ignition coil connectors.
• Remove the ignition coils using a socket wrench.
• Test each coil using a multimeter to ensure it operates within specified resistance values.
• Replace any faulty ignition coils with new ones.
• Reattach the ignition coils and connectors securely.

4. Fuel System Service

• Check the fuel filter for clogs; replace if it’s dirty or hasn’t been changed in the recommended interval.
• Clean or replace fuel injectors using a fuel injector cleaning kit to ensure proper fuel atomization.
• Reconnect all fuel lines and check for leaks.

5. Final Inspection

• Reconnect the negative battery terminal.
• Start the engine and allow it to idle to ensure smooth operation.
• Check for any leaks under the engine.
