Troubleshooting a car on the road (Opel Astra G)

Below are instructions for troubleshooting the most common faults and breakdowns that occur on the road. The relevant chapters provide information on repairs and the procedure for removing a particular unit or assembly.

If the engine does not start and the starter does not turn.

• Make sure the battery terminals are clean and the terminals are securely fastened.
• Turn on the headlights and try to start the engine. If the headlights glow very dimly when the engine is started, then the most likely reason for the engine not starting is a discharged battery. Jump-start the engine from another car's battery (see below).

If the engine does not start even though the starter is working properly.

• Check if there is fuel in the tank.
• Check for moisture on engine electrical components and devices.

Turn off the ignition and wipe away any moisture with a dry cloth. Apply a water-repellent spray (WD-40 or equivalent) on the fuel and ignition system connectors (see photo). Pay special attention to the low-voltage connector of the ignition coil and the high-voltage wires.

• A. Check the battery wire connections for tightness.
• B. Check the wiring harness connection on the left side of the engine compartment for tightness.
• C. Check the reliability of the high-voltage wire connection on the ignition coil (1.6L).
• D. Check the reliability of the wire connections on the air flow meter (1.8 l).
• E. Remove the engine cover and check the tightness of the wire connections on the ignition coils (1.8L).
