It is F30 (& F20) only, because when the seat supplier (I guess it's Lear) for BMW has changed the metal parts for new F30 chassis last year, they skipped the 'rust prevention coating' process (don't know why, but maybe cost reduction purpose?).
And then, when BMW noticed that there are many rusty seats, I guess that BMW has instructed the seat supplier to apply the 'rust prevention coating' again, since Nov.1, 2012 production.
So, BMW NA may offer to replace all the "un-protected' seats with new "protected" seats, as BMW Korea did.
My cars:

BW44 - built Oct 29 to Nov 4
BW48 - built Nov 26 to Dec 2

I do hope neither of them has rust or will rust. I've asked the dealer to check my BW48 car.

The BW44 car seems to be ok ....... so far ...... I think ...... build time/date just by the skin of my teeth ...... maybe!

This problem is serious and extremely upsetting. UK F30 and F20 cars are also showing signs of seat base rust.
