Well a dealer would probably do it for you, free or not. On the mib2 firmware thread (link post 2 above) there was a conversation on whether 516 was better than 515 and the other way round a few years back. Then 515 disappeared from the mibsolution.one site so it became academic just leaving 516T. The later ones of 516 and 515 were recommended for fixing car play / Android auto issues. No a dealer would not pick up that the firmware has changed and wouldn't be bothered.
These DIY updates on mib2 are only an issue if you have had a retrofitter change your system to give customised performance screens. They were big at one time. Then people do their own firmware update and find the screen they paid for has gone but the standard performance screen which won't be enabled in an Arona in any case is retained. Built in ones are turned on and off by FeC codes. An update retains the FeC unless it's a customised one that updates the FeCs as well. The updates denoted by a T aren't customised.
During the firmware update you keep the engine running or on a battery and it completes after a few reboots. You don't interrupt that process. Yorkshire Retrofit provides a PDF of
how to do it on their site.
A firmware update SVM message will be set in the unit which dealers ignore. They can be cleared yourself with
Obdeleven Pro or VCDS etc. Those using the East Yorkshire Retrofit download or the mibsolution one won't have cleared them unless they got the
coding device. They won't know they have it set. It works happily with the flag set, ditto the map update workaround message which is more pesky to clear. These days the MQB Evo platform of the Leon 4 and
Formentor are so full of error messages and flags dealers don't look at them unless fault finding and passover the infotainment messages.
Clearing the SVM message if you have
Obdeleven Pro I covered here
Great straight to the point answers and fast uploaded examples. FIS Carbon (which version did you pick?) Will wait until you have done Lap timer and tested. Pointer will be doing on the weekend thanks for instructions Looking for Tyre pressure
coding was for this...

Nb. For mib2 standard you have to remain in train 5* means if it's a 5 train so updates are fine within the 5 train in this example. Mib2 standard had four or so trains 2*,3*, 4* and 5*. People want to jump trains, you can't as DIY. The likes of East Yorkshire provide or did provide a train jumping service sending the unit off too them. If you attempt to do it yourself you may end in a boot loop. Again our Yorkshire friends and associates have dug people out in the past where they have messed updates up. The units are taken a part, shorted across pins to get them sorted out. Once jump trains you can't update the unit yourself so people get told to get back on the train they came from. With later fixes the train they end up on might have the fixes. Basically VAG with mib2 standard retained the four trains and issued bug fixes to each train. Tile windows came in on later trains why people want to jump trains to switch from rotating windows to tiles.
Btw the thread started off on here as mib2, took a wander to mib3 and returned to mib2.
