Hey all. Purpose of this post is to let all know that the driveshaft pn ending in 866 that replaced the "defective" driveshaft can also fail and in our case catastrophically - happened w/o warning at 80 mph going over a slight change of grade (an overpass). The u joint went through cover panel behind left front wheel, melted right through it and then hit the fuel emissions line. Thank God, car did not catch fire or blow up. I was not aware of driveshaft issue and neither was my local shop nor two different Master Techs who are long done with being at the dealer. This part was installed in post April manufacture date 2013 E70s and is not covered by the recall/extended warranty on these vehicles. As the car could have caught fire and my daughter potentially killed I didn't take no when dealer said couldn't help as out of warranty. BMW repaired the vehicle at their cost - well over $30,000.

Notice the u-joint - no, I didn't put it in plasti-dip - was red hot and instantly went right though the panel. The white inside the hole is the fuel emissions line. The open motor pic is of the oil pan. Metal instantly went through the motor. i pushed for a new turbo as well as they were going to bolt old one back on and agreed with me that it should also be replaced.
