how do I fix my Volkswagen Golf Eighth Generation (2020-present) that stalls at stop signs

Solution

1. Preparation

• Gather tools such as a socket set, OBD-II scanner, multimeter, and cleaning supplies.
• Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Clean Throttle Body

• Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner to spray inside the throttle body and wipe it clean with a soft cloth.
• Reattach the air intake duct securely.

3. Inspect and Repair Fuel System

• Tools Required: Fuel pressure gauge, wrench set.
• Locate the fuel pressure test port on the fuel rail and connect the fuel pressure gauge.
• Start the engine and check the fuel pressure; it should match manufacturer specifications (typically around 50-60 psi).
• If pressure is low, check and replace the fuel filter if necessary, or inspect the fuel pump for proper operation.

4. Electrical System Check

• Tools Required: Multimeter.
• Check battery voltage; it should be above 12.6 volts with the engine off and above 14 volts with the engine running.
• Inspect battery terminals for corrosion and ensure connections are tight. Clean if necessary.
• If the battery is weak, replace it with a new one.

5. Software Update (if necessary)

• Tools Required: OBD-II scanner.
• If diagnostic codes indicate software-related issues, check for any available software updates for the vehicle’s ECU.
• Follow the manufacturer's instructions to perform the update if applicable.
