why does my Volkswagen Golf MK7 (2015-2019) have poor acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean or Replace Air Filter

• Locate the air filter housing and remove the cover.
• Take out the air filter and inspect it; clean it with compressed air or replace it if necessary.
• Reinstall the air filter and secure the housing cover.

3. Check and Replace Fuel Filter (if necessary)

• Locate the fuel filter; refer to the service manual for specific location details.
• Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect the fuel lines from the filter using appropriate tools.
• Install the new fuel filter, ensuring proper orientation and secure connections.

4. Clean Throttle Body

• Remove the throttle body from the intake manifold by unscrewing the bolts.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
• Reinstall the throttle body and torque to manufacturer specifications.

5. Inspect and Replace Ignition Components

• Remove the ignition coils from the spark plugs by unscrewing them.
• Inspect the spark plugs for wear; replace with OEM-spec plugs if necessary.
• Reinstall the ignition coils ensuring they are seated properly.

6. Inspect Exhaust System

• Visually inspect the exhaust system for any dents, rust, or blockages.
• If a blockage is suspected, consider performing a backpressure test.
• Replace any damaged components as needed.
