Diagnosis

Like many other components of a vehicle, the ignition coil is subject to a certain amount of wear.

Its service life is normally between 60,000 and 80,000 kilometres –

however, a variety of factors can lead to a reduced service life. Before replacing an ignition coil, these factors should be checked.

If a vehicle no longer starts up, the engine audibly misfires or the vehicle’s acceleration is significantly impaired, this may indicate a defective ignition coil. The same applies if the check engine lamp illuminates, the engine control unit switches to emergency mode or an error code is displayed.

A visual inspection and further diagnosis will be required.
