Hi all - the seat latch, on the top of the passenger seat that lets you recline it to get access to the backseat, is broken. It appears the crappy plastic inside the latch has broken from the cable inside. BMW wants $500+USD to fix. I found the part for roughly $100. Anyone ever try this? I'm fairly good at repairing things, but stumped as to where to start and can't find any kind of service info online for the passenger seat. Thanks all, happy tpo post pics of the outside of the latch for reference.
