First visit to the dealer

Interesting stuff. And great servicing dealer!
MOST of the fault codes were there at PDI!! (Pre Delivery Inspection and setup). If they had cleared them them, would have saved the dealer and me a lot of time~ Isn't that amazing?
Second, SOME of the codes are caused by the Over The Air software updates. Yup. When that is performed it disconnects this while updating. then reconnects and disconnects that, etc. Also not so well thought out in my opinion. Why not just clear the codes and faults the update created as the last step of the update?
Last was one I caused
Tried to use Carista to lower the passenger mirror in reverse (I posted on this elsewhere). For me, it lowers as expected, but NEVER returns to the normal position unless I do that manually. And since this is not a stock feature, they cannot do anything for me. Pity. I miss that.
And last, the reason the car does not alert me when I pull head into a spot with a wall in front of me is THERE ARE NO FRONT SENSORS!! That boggles my mind. There are on the rear, but not the front on the Taos.
So for reference, this is the list of faults. And suprisingly the dealer APPRECIATED the list rather than saying we'll just do our own diagnostics.

So, just got otu tthe Carista and decided to check now that I am home and three faults :0
Instrument cluster:
16777018 - Function restricted due to interrupted communications
16777022 - Function Restriction due to Interrupted Communications (BAP_NAV SD_0x32 keine Kommunikation)
16777030
Instrument cluster:
16777018 - Function restricted due to interrupted communications

Very interesting, thanks! And yes, sounds like a good service department you have there.
I'd be inclined to try clearing those three codes again. As long as the instrument cluster is working properly it doesn't sound like a problem. Sounds like a very intermittent thing to me. I did a quick search on the codes and apparently it's been fairly common in the past and addressed with software updates on other models.
Any time I've done a complete scan on any of my VWs over the last decade or so, it's about 50/50 whether there will be a fault code stored for something. Usually, unless it looks important or persistent, I will just shrug and clear it. If it is something to worry about it will show up as an obvious problem or a check engine light once it gets bad enough.
In fact, I pretty much stopped running full scans unless I was actually looking for something specific. If you go looking for fault codes you are likely to find some! Most of the time they are nothing to be overly concerned about.

The codes should be the same across all VW products, including other brands such as Seat.
I don't know of anything which explains them any deeper than the description itself.
Fault codes are really a diagnostic tool. If a problem occurs, stored fault codes can help diagnose the real problem. The same code can be stored for numerous different root causes, so some detective work is also involved. A fault code is, in itself, not a fault. It's just saying, "Hey this thing happened - it's really not supposed to do that!". It can be something very minor or transient - just unusual enough to log it as something interesting. Big things, sure, turn on the CEL.
In the case of the instrument cluster codes, it could be something as simple as a software bug which causes a lack of communication for a fraction of a second longer than allowed. Since it seems to be a relatively common fault code, this is actually a fairly likely scenario.
Once in a while when I start the car, I can't change the view in the instrument cluster. If I shut it off and restart it works again. Clearly a bug, or it is getting into an unresponsive state. Maybe this stores a code? I don't know - I've never checked them on the Taos.
Maybe Carista itself, or any of the other diagnostic tools, disrupts bus traffic long enough to set a code now and then? Who knows?
I guess not every fault code is something that needs, or can be, fixed. The vast majority of owners will never know about any codes stored in their cars. I'm pretty sure dealers will simply clear the odd minor code here and there if the customer has no complaints about the vehicle.
With cars as complex, computerized, and loaded with sensors, it's not surprising that things occasionally happen outside of expected design parameters. Life's too short to worry about every code!

Except for the ones that have you shut down on a moving highwayLife's too short to worry about every code!
Haha, true. Though they usually get logged only after it happens.Except for the ones that have you shut down on a moving highway
I've seen a few reports of similar things from other manufacturers recently. The electric Ford Mustang has a stop sale on it now for shutting down or just failing to start. And another one (Honda Pilot?) that would shut down randomly too.
I loved it when I just had to carry a spare set of points in my '71 Beetle in case the crappy Lucas ones fell apart...
Where can I locate these codes, or is this something the dealership provided to you?Interesting stuff. And great servicing dealer!

Buy a device and smartphone program. I use Carista. And if you noticed, I told the dealer the faults which they confirmed. Not the other way around.
There are other similar devices and programs. Search around. I like mine but never tried another.

You can go to a local auto parts store and they can connect a code reader and pull up the codes, this is a service they provide for free usually, but be sure to ask first
