2002 Jetta Diesel starting problem

Colder mornings the glowplug light comes on only for couple seconds
and lots of cranking to start, lots of smoke due unburned fuel. Rest
of day it is warmer & starts OK. Replaced coolant temp sensor thing
that it sent the engine temp but no change. If I turn key on/off six
times alowing glowplug warmup each time start is OK. Any suggestion
where I could go next by myself? (not to a repair shop)

If glow plugs aren't the problem, then check glow control unit or
connections to the temp sensor.
