Faultmate Genesis
Below is a link to something that does not quite exist yet, or more correctly, is still in Beta and is very much more than a code reader.
The idea is that you purchase a license that provides some software and you also obtain a proprietary cable that connects between the vehicle OBD port and for example, your laptop. You then have your laptop connected to the internet via a Cat5 cable or perhaps WiFi - does not matter as long as you have a fairly fast internet connection.
If you know how Faultmate software works for a specific operation, you access the BlackBox site and do the whatever yourself, probably for an additional single use once only software fee.
This is what the beta is all about I gather - for the most part the system works hardware wise; the question is how to bill fairly.
Alternatively, and this is what I like, one can instead connect with a LR3/D3 guru who does know how the Faultmate software works and has the multi-vehicle all software license and just pay them to do the whatever.
For me, this sounds great as I think actually making changes to the Car Configuration File, (CCF), is only easy if you know what you are doing. As with all this computer stuff, there is a learning curve. Plug and play is a term commonly used by the seller, bleeding edge is more common with the user.
