The second unit is VW group specific.
If that's what your looking for try VCDS, pretty close to a factory scan tool in performance for a bargain price, you would need a Windows laptop though.
I don't know about Chrysler/Jeep (we don't see many here in the UK) but Eric from SMA uses his factory tool a lot on them despite having a few top of the line generic scan tools from Bosch/Autel etc.
If it's for DIY and you only have a couple of brands to deal with, I would look at manufacturer specific tools to be honest (either tools that emulate factory tools like VCDS or FORscan or in some cases actual factory tools work out cheaper!!)
Might be worth researching something like this (I've not used it)
