my Skoda Octavia NFL (2020-Present) headlights keep flickering, what could be wrong?

Solution

1. Preparation

• Gather tools and parts needed.
• Disconnect the battery to ensure safety.
• Tools required: Socket set, Multimeter, OBD-II scanner.

2. Inspect and Replace Bulbs

• Sub-steps:
  1. Remove the headlight assembly by unscrewing the mounting bolts.
  2. Disconnect the headlight connector from the bulb.
  3. Remove the bulb by twisting it counterclockwise.
  4. Inspect the bulb for any signs of damage; replace with OEM-approved bulbs if necessary.
  5. Reinstall the bulb, ensuring it is secure, then reconnect the headlight assembly.

3. Check Wiring and Connections

• Sub-steps:
  1. Inspect the wiring harness for any visible damage or corrosion.
  2. Check all connections for tightness and cleanliness; clean corroded contacts with electrical contact cleaner.
  3. Re-secure any loose connections.

4. Inspect and Test Battery and Alternator

• Sub-steps:
  1. Use a multimeter to measure the battery voltage; it should read between 12.4V to 12.7V with the engine off.
  2. Start the engine and measure the voltage again; it should be between 13.7V and 14.7V to confirm the alternator is functioning properly.
  3. If voltage readings are outside these ranges, consider replacing the battery or alternator.

5. Test or Replace Headlight Relay

• Sub-steps:
  1. Locate the headlight relay in the fuse box.
  2. Remove the relay and test it with a multimeter to check for continuity.
  3. If faulty, replace the relay with a new one.
