ok, new to VW and the car. what is vcds or whatever it's called and can these be done by the maint guys at the dealer or is this beyond there realm or obdeleven the only choice. thanks
There are a number of different manufacturers of diagnostic cables for VW/Audi/Skoda vehicles in the VAG group. A Google search will identify them if you are interested! The more common cables are VCDS from Ross-Tech, VAGCOM Pro from VAG-tech, ODIS -from VW and the newer generation bluetooth dongles (not cables) like OBDeleven (OBD11).
All these cables have their advantages/disadvantages. I personally prefer the newest VCDS cable - HEX NET, because it is very stable product and it doesn't require any ongoing fees - but it is expensive! HEX NET can also be used as a dongle (WIFI), or as a cable! I have a VAGCOM Pro cable as well - its good too, but I wouldn't recommend it if you are not an experienced cable user as it's not easy to use - plus it's also expensive and there are ongoing fees!!
Which option suits you depends on your personal preference and how you intend to use the device - and what price you are prepared to pay! Because you are a newbie, or if you don't believe that you will be a big-user - it might be better to start with a "low-end" device like OBD11.
OBD11 can only be used if you have a good internet signal at the point-of-use. If you garage your car in a basement, consider this aspect! The other aspect of OBD11 is the Android operating platform (not sure that it can be used on Apple devices - I think not). I find OBD11 to be very slow compared to HEX NET and it doesn't have some of the VCDS features that I find to be useful, but it is much cheaper -so I can forgive OBD11 for these deficiencies!
But the choice is entirely yours!!

PS: As to your question about VW dealerships, they generally don't/won't make the sorts of changes that are discussed here. This doesn't mean that they are somehow deficient in their skills - it's just that VW Head Office doesn't condone making these types of changes as a post sale service. VW likes their vehicles to have standard features as per factory settings!
PPS: The final point that's worth noting (given your newbie status) is that making changes to the settings in your brand-new car has its benefits - but it also has its risks. Proceed carefully, try to make a few errors if at all possible (because this is how you will learn), but make sure that the errors are reversible!!
PPPS: .........And a final, final - very important point. DON'T UNDER ANY CIRCUMSTANCES BUY A PIRATE/FAKE CABLE!! Don't fool yourself into believing that you are somehow innocent in the act of IP theft simply because you are a buyer. Such considerations are self-serving nonsense!! Those that do buy fake cables invariable find-out that their purchases use out-of-date software that won't work on many of the newer features of the mk7 (the software can't be updated!!)
