  WARNING
The ceramic glow plugs → Fig. are sensitive to jolts and bending. For this reason a glow plug which has dropped from a small height (approx. 2 cm) must not be used, even if there is no obvious damage. It is absolutely necessary to follow the installation instructions, otherwise the heater pin of the glow plug can break and cause engine damage.
