why does my Volkswagen Golf MK7 (2015-2019) stutter when I accelerate

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to ensure safety while working on electrical components.

2. Replace Spark Plugs

• Remove the engine cover if applicable.
• Use a socket set to remove the ignition coil bolts and carefully lift out the coils.
• Remove old spark plugs using a spark plug socket and inspect for wear.
• Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications (typically around 0.028 inches).
• Reinstall ignition coils and secure them with bolts.

3. Inspect and Replace Ignition Coils (if necessary)

• If diagnostic steps indicated faulty ignition coils, remove them as described in the previous step.
• Install new ignition coils, ensuring they are seated properly on the spark plugs.
• Reconnect the electrical connectors and replace any covers.

4. Check Fuel System

• Ensure the fuel filter is clean; replace it if necessary.
• Inspect fuel injectors for proper operation; clean or replace if clogged.
• Ensure the fuel pump is functioning correctly; replace it if fuel pressure is inadequate.

5. Reconnect Battery and Clear Codes

• Reconnect the battery once all repairs are complete.
• Use the OBD-II scanner to clear any stored error codes.
