I'd be thinking 'burning oil' with blue smoke , cold damp engine or water leak if white smoke plus the jolly old black stuff with any standard diesel is fairly norm --- unless it's been remapped by Gus or Adie , in which case it shouldn't smoke at all , mine doesn't but did as standard.

 

Slight grey smoke on mine at startup. When being MOT'd both the tester and I have noted the smell is quite strong, makes your eyes water a bit. Accompanied with a small amount of visible smoke on idle. It always passes the smoke test though. No idea what it is like on the move.

 

Glow plugs
Injectors not closing properly
Head gasket gone
Glazed cylinders

 

my swirl flaps are locked in the open position, so on a cold start, I get a bit of blue smoke ....as its coming out the exhaust instead of being re-circulated.

 

I get a puff of white/gray smoke on cold startup. However, I have no smoke on idle on a warm engine and have always had an easy smoke test pass at MOT. I have no other symptoms so I don't worry about it. Basically, a stone cold diesel engine will not combust cleanly. My old Petter generator (150 cc) used to emit 10x the amount of smoke on startup but ran clean once warm

Mine is the same and really only became noticeable after the EGR was surgically removed! Normally the majority of exhaust gases would be recirculated but without the EGR it can't happen. All is well on hot restarts though.

 

Do you do short trips a lot? I had similar, not only on startup but when i gave it some moderate beans....took it out the other week, redlined it in all gears and when i hit the throttle in 3rd a mahoosive cloud of black smoke billowed out the back. Been ok since!

 

White smoke at start up is usually unburnt diesel and water vapour. I would check the glow plug system first
