Hi,
I have a e46 year 2004.
I want to check a maximum of things in my car (but don't want to spend $1000 !!).
I heard about DIS, GT1, INPA, EDIABAS, WinFKP, SSS, NCS .... what I must take ? Which interface I have to buy ?

Thanks

DIS, GT1, and SSS is all BMW tools that you don't have acess too. I have never even heard of the other four.

LOL. you can buy a GT1 if you wanna pay $16,000. then even more money for the updated software every year.

LOL. you can buy a GT1 if you wanna pay $16,000. That only buys you the GT1 and its docking bay. You still need a diagnostic head, OBDII cable, DIS software, TIS software, MFK cable (if you want to use its multimeter/scope function), LAN cable with crossover connectors, batteries... If you want to go all-out, you can get the trolley with the MIB and all the MFKs, amp clamps, pressure sensor, etc. :stickoutt
