Hi there, As advised i'm starting this thread as i want to retrofit MFSW to my pre 06 A3 8P. I would like to ear from you what parts are needed. I know a new airbag control module is needed. Don't really know what the PN should be for a 3 door and with front driver/passenger airbags and front side airbagsand also curtain airbags. I was told that a new slip ring is also needed this i think the D version is ok. Am i right? About the wiring. Is it a huge wiring or a simple one? Sorry for these questions. Thanks in advance. Best regards.
