Still think your 135i/335i... has a LSD... all one needs to do is jack up the rear wheels off the ground and spin the rear tires by hand(while the car hangs up in the air)...

Both wheels spin the same direction = LSD
one wheel spins forward while the opposite side wheel spins in the other direction = open diff, no LSD.
This is not always the case. I've tested the tires spinning in the same direction on several cars and it depends on the type of LSD that's used. Several cars with factor or aftermarket LSD's spun in opposite directions on the lift but on the road always put both down.
