If your 2001 Mercedes C180 has trouble starting, there are several common problems that you should check for before you call your local mechanic. By diagnosing and repairing the problem yourself, you could potentially save money on the mechanic's and towing fees. If you are unable to diagnose the problem yourself, it may be necessary to have it diagnosed and repaired by a qualified repair technician.
Check the fuse box for any blown fuse. Pay close attention to fuses that are directly related to the starting of the vehicle, such as the ignition and starter fuses. Refer to the diagram on the fuse box to locate each fuse and replace if necessary.
Open the bonnet and check the battery for corrosion or loose terminal connections. This could prevent power from reaching the starter. Clean corrosion from the battery terminals and cable leads with a wire brush. Use a wrench to tighten the battery cable leads securely.
Turn the key to the "On" position and inspect the dashboard for warning lights. Look for low fuel, low oil or check engine lights.
Turn on the headlights. If the headlights or interior lights are dim, the battery may not have enough of a charge to start the car.
Note any unusual sounds when you crank the engine. Rapid clicking noises indicates a bad starter. Other sounds such as knocking, grinding or squealing may indicate a major problem that will need to be diagnosed by a qualified mechanic.
