Mercedes-Benz s123 300TD Hard to start- Glowplugs?

In this video I have a MB S123 in the garage. It has multiple problems, but the main problem today is that it is really hard to get going. It cranks and tries to start and smokes a lot of diesel smoke... My guess is that it is related to the glowplug or preheat system om the car.
