I am looking at upgrading my 2003 Z4 seats. I currently have the standard black leather with electric adjusted & heated seats but I would like to upgrade them to the msport black leather with electric adjusted & heated seats. I have been eyeing up the msport seats for a while but have been focusing on making sure the Z is in good driveable condition.
I have tried to look around on the forum to find out if it is possible and what I would need to do to fit the seats but it has been difficult to find anything for my situation (most seem to be adding in the electric options). There seems to be a lot of conflicting information about if it's possible and what you need to do. The most useful post I have found is; https://z4-forum.com/forum/viewtopi...2DCh91Io6pV8Eoa_dw_aem_iXkoykDs33PJoZfHxwX_VA
This suggests I need a bypass unit to get the occupancy sensor to work in the passenger seat. I have also seen/heard that the pre-facelift Z4 models don't have the same electrical connector as the facelift for the seats so they aren't compatible if I get the seats off a facelift car. I have spoken to my local parts guy who I am sure is on the forum & he said that Z4s made before 09/2003 (which mine is earlier) need a 2-wire mod to get the electric functions to work I think.
Is there a way to avoid messing around with the electrics & still have full functionality? I have had issues with the airbag light for my first 2 years of Z4 ownership & have now been without it for nearly a year so I don't want to create an electrical issue.
If anyone has any experience & knowledge or knows of any forum pages that address this, I would be extremely grateful if you could share it.
