Bosch Glow Plug

Diesel engines don't have spark plugs or an ignition system of any kind so it's up to the glow plugs to get it going when the engine is cold or ambient temperatures are low.

While there is no scheduled replacement interval for glow plugs they do have a limited lifespan and are often forgotten about until they fail. The amount of heat which a glow plug produces diminishes over time and this causes the engine to become progressively harder to start in cold weather. For that reason it is advisable to replace the glow plugs every 40,000-60,000 miles.
