Not much is involved. Call and make sure the dealer has the required parts and then schedule an appointment. I did mine one at a time. Once they wanted to replace the OFHG and VCG. The second visit they didn't find anything. I have heard of people being told a lot of work is needed. Maybe it was needed and maybe it wasn't.Ok .. Bmw emailed me back
Apparently the wiring recall was done but not the airbag recall driver & pass.
What's involved in that ??
