I have read that a clogged/dirty air filter wont help with the cold starts, so I am going to change the air filter in the next few weeks, as mine has done nearly 90000km on the original.

Clogged air filter will just give you black smoke thru rev range and a performance drop.
White smoke smelling of Diesel,is generally related to:-
-Glow plugs.First thing and easiest to check.Try waiting 25 secs before cranking engine.If you find that by this mehod it smokes less on start-up,then you may have a bad plug(s)
-
Leaking injector(s).As the car is stationery overnight for example,a leaking injector will leak diesel to chamber and in the morning when you start it up,engine wont be able to burn it and will expel it out of the exhaust.
These are the most common faults on ANY car .May also be sensor related,such as fuel pressure ..but you would have a EML on!
Good luck
