Hi

Have a 4 series no coms with FEM and nothing happens on pushing start button.
Checked FEM is getting power BTW.


My question is how compatible are 2nd-hand off ebay?
See manual transmission/auto must be same but any other guide like p/n

Ie i've gone for same "FEM-LR01-ZB7_HIGH_CA"
But also see "FEM-LR01-ZB9-MID_ELV_IB" much cheaper

ELV referring to steering lock? Other p/n but this stands out

Thanks
