A quick 'How To' guide on removing the Z3 seat from the seat base, not sure if it's already been covered, but sure I read someone asking about it recently.

I have the seat electronically up as high and far forward as possible for access reasons later

I've not documented how to remove the seat but it's 4 bolts - then unclipping the electrics x3 usually - this is best done with the battery disconnected.

First I remove the seat belt tensioner/holder/harness with a 50Torx bit - can be very tight.

Then to get the (yellow) seat belt/airbag sensor out you need to unclip (prise) the two plastic clips off where the upper and lower leather panels join and prise off or snip the black bungs.

Then two 13mm bolts (you can see the second one at the bottom of this picture with a yellow dot on it) - much easier if the seat is in its highest position

Then off with the side base - with the manual back raiser and electric motor controls - 3 Phillips screws

To remove this side base you need to release the metal nipples on the back rest adjustment cable x2 - a bit of wiggling and maybe gentle open the jaws

To gain access to the last (black plastic) guides that hold the metal cable in, you need to release the motors by unclipping then and then removing the static side of the harness by gently pushing the retaining (central) clip sideways.

Then you need to lift the seat base upwards - it is held on by two 'teeth' they need a jiggle - it is quite heavy so be careful, easiest position is with the seat back upright with the front of the headrest on the floor and the front of the seat base on the floor.

With that almost off you can now get the black retaining holders off, gentle prise again - this angled screwdriver is perfect.

It should now all 'fall apart'

Leaving you proud and with three parts

FYI the right hand side in this picture is the front - the motor with the white connector (with two spindles coming out) is the forward/backward one. The central one with a single outlet (black connector) controls the up/down motion.

Hope that helps someone

Should the seats on all models go up/down forwards/backwards.

Both my seats will go forward/backwards but neither of them will go up or down.

Driver’s side always has up/down

Passengers side not always, the button is the give away
