| Handling ceramic glow plugs |
| Important: Note the following points regarding ceramic glow plugs: |
Caution | t
| Due to the special properties of the material used, ceramic glow plugs are easily damaged and require extra care when handling and removing/installing. Always observe the special instructions when removing and installing ceramic glow plugs → Rep. gr.28. |
| t
| Transport and store only in original packaging or packed separately in bubble wrap. |
| t
| Do not remove new ceramic glow plugs from packaging until they are ready to be fitted. |
| t
| Ceramic glow plugs are sensitive to knocks and bending. For this reason, ceramic glow plugs which have been dropped (even from a height of only about 2 cm) must not be installed, even if no damage is apparent (hair-line cracks may not be visible). |
| t
| Always install a new ceramic glow plug if you are not sure the old one is in perfect condition. |
| t
| Damaged glow plugs (e.g. heater pin of the glow plug is damaged) will invariably cause engine damage. |
| t
| If the heater pin of the glow plug is damaged, the fragments must be removed from the combustion chamber before starting the engine for the first time; otherwise this will invariably cause mechanical damage (piston seizure). |
| t
| The ceramic glow plugs must not be removed when checking cylinder compression. |
| t
| The software of the engine control unit is specifically adapted to either the ceramic or the metal glow plugs, so it is important to install the correct type. |
| t
| Mixed installation of ceramic glow plugs and metal glow plugs on the same engine is not permissible. |
