Are your injectors codes the same as what show on ecu?
Yes they are, but I have run TD5's with the wrong codes and it doesn't do this.

Fair one mate
After the initial spasm the defender is fine all day.
@Discodevon do you think this is injector related?

Ah the landie fairie has been at work. My truck has decided to start now as well (after I realised I had put the vacuum tubes wrong way round on the ECU solenoid)
10 minutes later it was back to it's old self - the more erratic this is the more I think poor fuel / fuel contamination
Pretty normal from a cold start (puff of black) as start fuel is applied and also pretty normal for condensation (water vapour) to be seen until engine is warm. Roughness at idle from a cold start is usually a glow plug or two gone down. As the cylinders heat and chime in it goes away.
The glow plugs were fine but replaced with new (and tested) NGK plugs anyway. This is normal ? I've had this defender for about 6 years and it's never done it before...
Black smoke normal from cold start. White smoke looks like a cold cylinder not burning fuel to me. Then when it chimes it it goes away. If it was contaminated fuel it would be like that all the time.
cheers wammers, you reckon it's normal then or a sign of something else?
It's not a new motor so some deterioration is normal. Black smoke on cold start i would not worry about. White smoke and misfire check glow plugs, check compression's.
Done all that!
Do it again something is causing it.

Can you swap injectors over and see if that changes anything?
I've put a completely different set in and coded them with no change.

Have you swapped electric throttle pedal with another?
Not for about 5 years - what could that prove? There doesn't appear to be anything untoward with the throttle inputs on diagnostics

maybe worth checking your fuel pressure
over the past few months mine started to blow some white smoke on engine start up even when the engine is warm and this is also intermittent ....white smoke with a miss only on start up only
at first i thought maybe a dribbly injector and depending where the injector comes to rest when engine is off .... like i said mine is intermittent and curtainly not a glow plug issue as it can sit for days weeks the first start no smoke
i have noticed on my fuel pressure gauge i am now running 50 psi compared to when i first installed my fuel pressure gauge a few year back reading just a little over 60 psi
i have also noticed some days my fuel pressure averages around 55 psi depending on how the regulator feels on the day .... or the fuel pressure gasket is allowing some internal leakage draining the fuel from the head or a regulator fault
also some injector cleaners left in the system to long has long term affects
