So far, I have had good success with BMW.
i used Foxwell-made NT510 handheld tool from http://www.foxwellshop.com/
all BMW’s supported auto vin & autoscan, was able to get a quick easy accurate report of issues.

2010 BMW e88:
reprogramming of injector values and Engine idol speeds and it can be used on it,so far ,everything is OK,

2008 BMW E93:
register a new battery- SUCCESS

2006 BMW X3:
able to find 2 misfires because of bad plugs.

2009 BMW z4:
able to diagnose and find bad HAL sensors stopping the roof from retracting

2009 bmw 335i (American):
Managed to do battery registration

BMW X5 E53:
Used NT510 scanner to get all of the air out of ABS block--> OK

BMW E39 M5(2003)
X5 E53 4.6is (2003)
540iT (1999):
I bit the bullet and ordered one also along with a bentley manual. I've got 3 BMWs E39 M5(2003), X5 E53 4.6is (2003), and 540iT (1999). Because it has specific BMW codes it seams worth the investment and well beyond a peak code reader.

BMW E90:
Bi-directional control tests and oil light reset... no issues

2009 BMW 335 Diesel E90
all functions in the list are tested without issues
