[ASK] How to activate lumbar and backseat control on M3 seats

Hiya!

I have just recently retrofit M3 seats to my 335i.

All standard functions buttons functioned well as the previous seats were electric.

However, the 2 front buttons which control the lumbar and backrests adjustments do not work.

I want to make them work.

Anybody here had similar experience?

I have searched throguh google and this orum but unable to find this specific topic.

Do I need coding for this?

Please help.



Thank you in advance for all inputs given.

Josh
