Yeh swap them over.

Hope you don't get popping movement with your seats, it's maddening.

I'll have to get it fixed one day by BMW.

So you need to add an extra pin into the yellow connector that plugs into the bottom of the seat.

This is pin 7, you'll see a terminal in that location for the seat side but obviously not on the vehicle wiring harness.

The part for the terminal is 61130005197, crimp one of these on to a good length of wire. The wire can then be routed to follow the oem wiring harness. I did this while the seats were still out. Removed the plastic trims at the edge of the carpet, ran the wire up the edge of the car to the footwell.

Removed the lower trim panel under the dash and utilised the feed for the footwell lamp. So the footwell light has 4 wires, one earth brown or brown with a trace. Two others that are mainly white with either red or blue trace (these feed ambient light either white or the orange) and then the final wire is red or red with a trace (sorry can't remember exactly) forgot pics also. This one you can tap into for your seat illumination.

Tidy up wiring, secure in place with zip ties if needed and re fit panels. Then repeat for the other side.

So now the seat light works at the same time as the footwell light. So when a door is opened or the main full interior lights are on.

This is not quite the factory method as this would be wired into the FEM control unit.
But my method I found fairly straight forward as I could keep them separate on each side as the other way would need both wires running to one control unit.

I would recommend doing this with the battery disconnected and the seat out. Any more info give me a shout.

I did a whole driving course two days ago and was never aware of popping from the seat. Only thing different is adjusted my chair to be slightly closer to the wheel, maybe the thread in one area is damaged and has play? Moving it into thread in better condition has eliminated it?

Yes. Just make sure you use the underseat modules from your original seats (and make sure the battery is disconnected before you unplug anything...)

Understood. I'm desperate to do something about it asap as the standard seats are pretty crap

Also just to be certain, the m4 rear seats just need a bracket to then be fitted without any other modifications?

As I fitted M2C front seats with the blue stitching, I left the rears alone.

Well, noting I have the 6MT, it seems more that the pedals are offset than the seat being squint.

Just be happy you didn't try retrofitting the the Carbon Fibre-shelled buckets from the current M4...

How tough is it?

That is if you can find them.

Well, availability aside, probably no more difficult as a retrofit than seats from the M2C, it's just that the shape of the seat frame would - in conjunction with the offset pedals - make for a notably uncomfortable driving position.

The buttons may not work. The M2C and M4 are a stupid simple swap into OG.

Definitely.

I have the M2C seats in.

For the price of the G series carbon seats I can do a lot of other mods!!
