Scan tools.
 

Do any owners have scan tools that they are particularly happy with? Thank you.

None, exept factory are perfect...having said that, niether are the factory.
I think that OBD.COM and Ross Tech have the most comprhensive tool for VW and they say they are working on a BMW tool.

My Snap-On BMW and Mercedes cartriges are okay but lack some finer points.
Along with my Snap-On Vantage and a digital meter I seem to have gotten most problems corrected that have arrived here.

This is of course providing I can get the correct wiring schematic.
This means paying to access the factory sites though, and at the present cost, it is value for money.:)

My most loathed piece of equipment is the 'Retriver' from Assenmacher.:mad:

Good Scan Tool
 

I have an Actron OBD-II scan tool that seems to work very well. It sells for around $70 more or less, and provides a good readout and series of functions to ID the codes in your car code storage area. BC

I have Ross-Tech for my VW and love it! Will also read emissions related info (anything that will activate the CEL) on the MBZ, as will OBD2. However there is no way to read the transmission, 4wd, SRS, etc related codes on a Mercedes, that I know of.

I have not explored the options from Snap-on, they are quite expensive for the amateur wrench.
