20100412 on Uwe's insistance: tentative add of 0x0B for 7E/7F
The T5 (which uses the same gateway as a lot of the Polotariat) has a very dumb arrangement where 0x0B exists but on K and not present in the . With having no way of knowing in advance if that control module is going to be installed along with one of those gateways, we also scan for 0x0B (on the very slow K line) and present it in the installed modules list.
However when starts an autoscan, the first thing it does is get a VIN, and from that there's a couple easy things we can do to exclude the presence of 0x0B, such as being a 6R , 6J, AA, AT chassis code. That explains why it's not in the autoscan results and scanning list. Santos prompted that tweak when he mentionned how annoying it was that 0x0B was getting scanned for every time on his LOW- Jetta.
When we get the installed modules tab, however, the waiting time for the to populate is already borderline acceptable, and I don't want to lengthen it even further by connecting to the engine (which takes a long time to setup on legacy interfaces) to query a VIN just so the Polotariat can benefit from what would be a cosmetic fix
