Some further information:
My last trip home this afternoon, when I started it, I sat there for 10-15 seconds in reverse with the accelerator flat to the floor & nothing happening except lots of white smoke before it started moving to reverse out of my parking spot. Put it in D & it took off more or less normally except for the smoke. Once it got going it was fine as far as driveability goes (maybe down on power).
I didn't have to stop on the way home - only left turns. I had the rear camera switched on to keep an eye on things & what I saw was it not smoking all the time, but when I accelerated away from a junction it smoked bad up to about 2000rpm when the turbo kicked in & the smoke stopped. If I was cruising at 60 & not accelerating or slowing down it smoked too.
Earlier in the day whenever I had to stop (stop sign/traffic light etc) it would again take 5-10 seconds (sometimes longer) to get going again accompanied by copious smoke until the turbo kicked around 2000rpm.

This update helps with ideas.
It's not the huge white cloud I thought you where talking off, that's a good sign.
It shows the smoke only as the turbo is trying to help so I'd be thinking about delaminating hoses either side of the intercooler.
Some describe this as black smoke but it could be interpretation.

I have brand new (<500km) silicone turbo hoses so it ain't that.

"Check your oil level as well. Mine did what yours was doing when the head cracked filled the sump with diesel." blue mini

Oil level is not changing (except the rocker cover gasket leak) so I'm not getting diesel in the sump...

It is a huge white cloud when I'm trying to get going...
Definitely white - I had black smoke before I replaced the turbo hoses & there's no way it could be described as black

Check new hose clamps? One of my new silicone hose ones became so loose it fell off the hose altogether under heavy accelleration. When I went to check the silicone clamps, 5 of the 6 were quite loose.

Similar problem but not quite the same D2/td5 1999 almost 280k Intermittent, usually happens on an incline or hill, accelerating up hill &have to back off for traffic or speed limit signs, put the foot down again &nothing for 2 3 4 5 seconds with a big cloud grey/blue smoke then everything is fine again. The oil level remains constant with no indication of coolant contamination & the coolant seems free of oil. Does seem to use a bit of coolant but can find no obvious leaks. Other than this occasional problem car idles & runs fine..

any advice would be much appreciated

The whole revvving and not moving thing sounds like transfer case not having enough oil. Thats what happened to me when i blew the oil cooler line. I got lots of smoke because the oil was hitting the hot surfaces and i was revving and not going anywhere. Im not anywhere near as experienced mechanically as most of the others on the forum so if the experts can tell you its not it then great. Otherwise its easy to check.

the point is its NOT revving - flat to the floor & 800rpm for 10-15 seconds

just tested a few things - turbo hose clamps are tight, turbo wastegate free, turbo all OK - free turning, no broken vanes (Intake side) no play in bearings.
Started it up - no smoke at idle, started smoking & sounding like running on 4 cylinders at 1000rpm, kept smoking up to 3500rpm.
So I'm thinking an injector seal leading to one cylinder not firing.
Blow-past the injector would also make sense with my previous post of the camshaft front cover coming off, except the breather is clear so I'm not sure how the rocker cover would be pressurising.
Any thoughts O Mighty Guru's? (serious, not taking the p**s)
