Injectors stuck in cylinder head

Having found that my Turbo is so badly coked up and the actuator is stuck I am now attempting to remove the Turbo.!! Enough said !! Anyway having discovered that the complete rocker cover and air filter housing also need removing to allow access to the three bolts on the top of the exhaust manifold - yet another design great from BMW!! - I came across the dreaded "VERY" stuck injector. I'm sure that i tried everything that other members must have to free it off without success and smashing the thing to bits came to mind !!
Any way after much tea and further thought I came up with an idea - which no doubt has probably already been tried - but here goes anyway: Cheapo slide hammer
I had an old injector knocking about from a Vivaro 1.9 engine so i removed the top from this and cut the fine threaded nut from the electrical connector. I cut a small length of tube and welded this to the nut and the other end to a long bolt from a motorcycle swing arm incorporating an old set of weighty pulleys from a lathe. See Photos. After soaking the injector overnight in Brake cleaner I removed the top from the stuck injector screwed on the tool and after half a dozen hefty pulls the world was a better place and there was a liberated injector sitting on the bench. Celebration tea after this.
As I mentioned before it may have already been tried and tested but if not the info may be of use to someone with the same problem.

Nice ghetto slide hammer, best thing it worked > i have one of these it works good to

There's actually no need to remove the air filter housing, as there are 3 holes in the bottom of the housing, positioned above the turbo to manifold bolts to minimise stripping down to access the turbo.

Those are the ones.

the are not ordinary bolt heads they are 12 pointed bolt heads but you may find a socket to undo them and what every you do put the 3 plugs back in as they keep heat away from the filter, it happened to me the man who did mine actually left one bolt out but also did not put the plugs back in he left them on top of the engine an I noticed them when I had to stop because of smoke coming out of the air filter if I had not stopped I think my car would have been on fire.

Thanks to all for the replies

I have removed the turbo successfully and purchased a new core.

The actuator and the vanes were clogged solid and were all cleaned and tested and now moving perfectly.
I have a problem when fitting the exhaust side. When I tighten the screws the actuator arm goes very stiff which is obviously not good. I have checked and double checked that I am fitting it correctly and everything is where it is supposed to be.

There is a metal shim fitted which is 0.35mm thick and I would like to purchase some others in different thicknesses to alleviate this but I can't find any listed or in fact on any diagrams of the 708366 turbo.

Anybody know where I can get these from?

Buy some shim stock from eBay or similar and make your own? With small shims, a cheap feeler gauge set could be used as handy shim stock.
