300 tdi disco bad starting in cold

hi guys,
yet another problem it must be the year for it...
when its very cold in the morning sometimes my disco takes ages to fire,when it does it chugs like hell,once ive blipped the throttle a load of white/greyish smoke bellows from its bum,after this its fine,no smoke,same power as usual,starts perfect the rest of the day even if its stood for 12 hours.it happens more than not but not all the time.just passed mot,i was told it is a very clean burner smoke wise.glow plugs fine/injectors not sure was going to change in summer last year just no pennies,serviced 2 weeks ago,new filters oil ect.checked water trap on front fuel filter no water,new timing belt/all timing bang on.
can someone shed some light on this as this disco i love it but its giving me some severe headaches lately.
cheers

Little pipes between the injectors (three of), renewed mine with fish tank pipe, one of the banjo nuts was loose as well , might be worth a chech first. Banjo nuts = little bolts on side of injectors that hold the pipes.

yu wanna be careful of those ickle Bajo fittings - eh Buster?

ok.so if the pipes were knackered or split/perished wouldnt they be wet with diesel.im er a bit thick when it comes to fueling on diesels,are wont be owt to do with compression or owt daft like that then as this has been mentioned,it also knocked quite loud when its cold i forgot that bit only for first 10 mins or so.
thanks

If the banjo bolts on the spill pipes are a wee bit loose air will get sucked in makin' it run a bit lumpy. Check them for tightness (go easy and don't over do it) or renew the copper washers either side of them and see if that makes any difference

Possibly be wet..... but they may let in air when engine cools down allowing the fuel to run back to tank.
Mine was a pig to start and chugged for a bit after.
put new leak off pipes on and it started instantly next morning and ticked over like a baby.
One of them was split and one of the banjos was loose. No leaking diesel though

It knocks louder when cold because it is getting excess fuel

badly seated injector, leaking manifold gasket or leaking head gasket.
and the heater plugs are on a timer and come on regardless, staying
on for up to 5 seconds even when engines running.
