In order to prevent damage to the engine, it is important to observe the following information concerning ceramic glow plugs:
- Ceramic glow plugs are very sensitive to impact shocks. Impact shocks cause invisible damage (hairline cracks) to the ceramic glow pin and lead to engine damage.
- It is not possible to check the ceramic glow pin for mechanical damage (e.g. hairline cracks).
- Only use ceramic glow plugs if the packaging is original and unopened.
- If the ceramic glow plugs have been dropped, it is essential that they be replaced.
- Only check glow plug with Diagnosis Assistance System (DAS).
- The glow plug must not be energized with 12 volts otherwise it can be destroyed.
