My dealer JUST called me, as I was reading this post. Funny!!
The seat parts are backordered, and will not even be released in Germany until mid July. The Service Manager told me, I can realistically expect the parts to arrive the first week of AUGUST!! He said A LOT of E70s are having driver seat problems...creaks, snaps, groans, rattles!! Sh*t...that's a lot of time, and summer driving with creaking & snapping!!

Major Bummer!!!
