I want to figure out the difference between Xtool X100 Pad2 and EZ500.And to see how many Volkswagen cars are able to Pad2?

Answer to their difference:

1.     VAG VW 4th 5th IMMO key programming (+& -)

XTOOL X100 PAD2 FULL Set can program VAG VW 4th 5th IMMO key, here a post on how to do:  http://blog.xtooleshop.com/xtool-x100-pad-2-full-set-program-vag-vw-4th-5th-immo-key/

If your XTOOL X100 PAD2 without VAG 4th 5th IMMO key programming function, order a KC100 adapter, this is a little bit expensive, maybe you contact the seller they would give you discount especially when they promote.

 

2.     4 system diagnosis VS full system diagnosis

You can see XTOOL X100 PAD2 have four systems diagnosis (Engine, Brakes, Central Electrics, Airbag), no full-system diagnosis. And XTOOL EZ500 have full-system diagnosis option. EZ500 is powerful with many functions and vehicle coverage, I already prepare a post on all EZ500 functions and testable car models & year:
