There is usually a clip that needs to be released by pushing down on a tab, they can be quite tight sometimes.
The connectors won't separate without the clip being released.

Would disconnecting the MAF throw up the MCSF light?

Yes, but it would run better than with a knackered MAF plugged in, so its often alright to do it to get you home, or try and diagnose a broken MAF.

I've disconnected it which is great and the result is great. Got all my power back thing is I don't want to pit it back on now, but would it do any damage If I did leave it off until I've found a replacement?

Leave it off - but you want to replace it sooner rather than later.

Also, it should feel a little better again with a better MAF plugged in, you've probably only got 90% of the power back

Don't try and find a cheap one, you need a genuine Bosch one or it won't run right. Try taking the old MAF element out of its housing, and Google search for the part number you find on it. You may find the same MAF sensor element fitted into a cheaper unit. For example, the 98-00 156 2.5 V6 MAF element is the same as found in a Vauxhall Corsa diesel.. Much cheaper buying from Vauxhall than Alfa.

Whatever you do, don't buy a cheap pattern part. It MUST be genuine Bosch, or it won't run right.
