What you could do is check the level on the ground. First step loosen the fill plug in the air. Drop it down and squeeze under to remove the plug. Start up the engine and let the fluid warm to 120 degrees. At that temp there should be a very very small stream coming out fill hole. Difficulty is positioning yourself so that you can the plug screwed in far enough by hand so it doesn't leak and you don't get burned. Then let it cool and you can raise the front to tighten to proper torque spec. Need to have new crush washer for the plug. That said, I would never do it that way. My suggestion is to buy two more jack stands and get it level in the air or have it done at a transmission shop familiar with BMW transmissions so you will be sure it is filled to proper level.
If you remove the plug BEFORE you start the engine, don't you immediately lose a bunch of fluid, as it not circulating but sitting in the pan, so the level is "high"? Wouldn't it be better to remove the fill plug once the engine is running?

My ZF GA6HP26Z is a little different to check than this, as I don't have a side fill plug - both drain and fill plugs are the bottom of the pan. Almost makes it easier, I guess... better access when the car is down. The general concept is still the same.

The power steering is fixed now.

But there is another leak. It looks like engine oil. I cleaned it up and took it for a drive and when I pulled back in the garage I had 2-3 drops formed underneath. The oil is dripping from somewhere above the steering rack - it's near impossible to see exactly where.

I've been reading and it looks like this could be a number of things - e.g. The alternator bracket. I know this car has had a remanufactured alternator fitted in the past. It's also had its valve stem seals repaired as well. Is there any other area I should check? I've got one of those cameras with a light on the end of them so will give it a go.

Not remove it, loosen it so you can turn it out with your fingers and then remove it after the engine is running.

Location of oil on diff, and the fact that you suspect the alternator bracket, I would investigate further. Take off the wheel well cover and have a looksy. Fun times ahead.
