Starter motor defective due to faulty ignition lock

If a defect is detected in the starter or starter motor on the vehicle models mentioned above, a possible cause may be a defective ignition lock. A worn or broken spring inside the ignition lock can cause the ignition lock not to return directly to the starting point after the starting process. As a result, the starter is operated longer than desired and remains switched on after the engine has started.

Damage assessment Before the new starter is installed, a damage assessment should be carried out on the removed unit. If the actual cause of damage to the vehicle is not rectified, the new component will also be damaged again. If damage is visible, such as a blue armature shaft or a milled pinion, this may be due to the starter continuing to run with the engine. In this case, the ignition lock should be checked and replaced if necessary.

In addition, prolonged starting processes can be triggered by poor starting behaviour from the engine.

The following tests should also be carried out:

Check electrical connections and earth connections for corrosion or damage
Check the ring gear on the flywheel for damage

This information may also apply to the vehicle manufacturers Vauxhall and Nissan with the same engine variants.
