On diesel it can be a glow plug. On my 1.7 cdti this message was only on first (cold) start, when it warms up there is no message because glow plugs are not used.
Locate glow plugs and test each with multimeter (ohms). Resistance shuld be low (0.9-1.3), if its 10+ or 0.0 then it has to be replaced!
Try first to warm it up, stop engine, remove the key, put the key and start it up. If message is missing then it is glow plug 100%
