Edit to add:
If you decide to go away from the BavAuto's, here's the link to the correct Bosch ones from Amazon. AMAZON SAYS THEY DON'T FIT, but that's not true, they are not taking into account the pre-vs-post 04/2006 change.
Ah, actually good that you mention that. And for reference, check this thread:

I spoke to a chap at a BMW specialising workshop and he said that he has encountered this problem a number of times. Apparently, the only difference is the centred or off-centred tab on the particular coil pack that causes the problem. The plug itself and the coil pack is otherwise the same. So according to him, all you do is simply cut those tabs off and presto it works. I have not tried this, and am only going according to what he said, but I have not been able to find any other difference aside from the silly wiring harness that is different along with the tab on the plug.

So, has anyone here experienced this and had success modifying the coil packs to just fit? Why BMW made this silly change is also beyond me! The "newer" type is in essence the older type as used in most of the E46 engines! Go figure...
