Many thanks in advance to all who can possibly help me.

To confirm, Z3 2000, 2.8, auto.owned nearly 10yrs, 28000 now 66180.

Having inspection confirmed need to replace the air bag passenger seat sensor mat following indication from the warning light/icon on dash board.

Reading about a number of solutions from the internet being unsure and with no knowlege which to trust as said would be most grateful for any advice.

You might want to try one of these:

Thank you btmaldon. I did see these but they didn't have any reviews or feedback to know if a viable option. Have you experience of them?

Not personally, but a few on here have and I know a couple of other people that have used these successfully.

I used one on my z3 works fine but you need to have some one to reset the warning light have a look on zroadser site
