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:
