Hello all. We just got a 2015 85D that is about to go out of warranty. Not having any issues with the car besides just replacing a rear half shaft and seal (which was pretty easy), but wanted to learn as much about the drive units as possible. I’ve been reading here and it seems that some units are more problematic than others but I’m not sure which motor(s) my car has. TPN on rear motor is 1037050-00-D. Is this considered the LDU that is prone to issues or has this revision been revised to be more reliable? if I’m missing this, is there a list of motor model numbers with years and descriptions somewhere? Thanx.
