📋 Procedure

1. ⚠ Ceramic glow plugs are sensitive to knocks and bending. For this reason a glow plug which has dropped from a small height (approx. 2 cm) must not be used. Even if no damage is apparent. It is absolutely necessary to follow the installation instructions, otherwise the heater pin of the glow plug can break and cause engine damage.Transport and store only in original packaging or packed separately in bubble wrap.Only remove ceramic glow plugs from their packaging immediately before installing them.If there is any doubt as to the condition of the ceramic glow plugs, they should be renewed without exception.Damaged ceramic glow plugs (e.g. heater pin of the glow plug is damaged) will invariably cause engine damage.If the heater pin of the glow plug is damaged, the fragments must be removed from the combustion chamber before the next starting of the engine, otherwise this will invariably cause mechanical damage.Do not oil or grease thread of cylinder head bore or of ceramic glow plug.It is not permissible to install a combination of ceramic and metallic glow plugs. — Connect .
2. Switch ignition on.
3. Check engine control unit J623 for event entries reference glow plugs using Guided fault finding.

6. Pull connectors off glow plugs.
7. Connect voltage testerV.A.G 1527B cable to battery positive (+), using clips from auxiliary measuring setV.A.G 1594C.
8. Place test probe of voltage testerV.A.G 1527B on each glow plug one after the other.
9. Connect wire of hand-held multimeterV.A.G 1526 E to relevant glow plug using auxiliary clips from auxiliary measuring setV.A.G 1594C.
