Solution

1. Preparation

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

2. Read and Clear Diagnostic Codes

Connect the OBD-II scanner to the port under the dashboard.
Turn on the ignition without starting the engine.
Read any stored trouble codes and write them down.
Clear the codes and recheck if they return after a test drive.

3. Inspect and Repair Electrical Components

Battery Check:
- Remove the battery terminals (negative first, then positive).
- Test the battery with a multimeter; replace if voltage is below 12.4V.
Alternator Check:
- Reconnect the battery and start the engine.
- Measure the voltage at the battery with the engine running; it should read between 13.7V and 14.7V.
- If below this range, consider replacing the alternator.

4. Inspect Fluid Levels

Brake Fluid:
- Open the hood and locate the brake fluid reservoir.
- Check the level; if low, top up with the recommended fluid (DOT 4).
Coolant:
- Check the engine coolant reservoir for proper levels.
- If low, add the correct type of coolant (G12 or G13 for Skoda).

5. Test & Verify Repairs

After any repairs, reconnect the battery.
Start the engine and observe if warning lights remain illuminated.
Take the vehicle for a test drive to ensure warning lights do not reappear.
