I've several times / and ways , and cannot find what seems like would be a good sticky for all the diagnostic cables / tools .
A comparative chart of all / or many of the [ this is part of the problem - too many names / labels for the same basic devices ] , the list of tools on either the vertical across the chart & columns showing functions , possibly a 3rd designator for yrs.
I bought a Ross-Tech Key-USB , while searching read about another Ross-Tech that was good for my car 03 TDI KII-USB , and on it went ;(
The reason being , is someone , almost everyone , has not played with [ what more than a dozen diagnostic cables , connectors , OBDII , etc. etc. ]
a through checking out could take days of reading .
And if someone wanted to have more features / maybe pro or close to pro , you start looking at $300 , $400 , +++
This kinda stuff even for a full blown shop [ I used to be ] now we are looking at $3,000 - $10,000 .
The last thing anyone at any level wants to do - is spend hundreds of dollars , or more , and find out they need to start shopping & spending even more .
