my Skoda Octavia NFL (2020-Present) headlights flicker while driving what to check

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Headlight Bulbs

• Tools Required: Socket set, gloves
• Remove the headlight assembly by unscrewing the mounting screws.
• Disconnect the electrical connector from the bulb.
• Remove the bulb by turning it counterclockwise.
• Inspect for any damage and replace with new bulbs if necessary.
• Reinstall the headlight assembly and reconnect the battery.

3. Check Wiring and Connections

• Tools Required: Multimeter, electrical contact cleaner
• Visually inspect the wiring harness for any signs of wear or damage.
• Use the multimeter to check for continuity in the wiring.
• Clean any corroded connections with electrical contact cleaner and ensure all connections are tight.

4. Test Battery and Alternator

• Tools Required: Multimeter
• Connect the multimeter to the battery terminals while the engine is running.
• Check the voltage; it should be between 13.7 to 14.7 volts.
• If the voltage is below this range, inspect the alternator and its connections.
• Consider replacing the alternator if it fails to deliver sufficient voltage.

5. Verify Ground Connections

• Tools Required: Socket set
• Locate the ground connections for the headlights and battery.
• Ensure all ground bolts are tight and free of corrosion.
• Clean any corroded ground points and re-tighten.
