After waiting over two weeks for the stock car which is undergoing updates, I asked the dealer for updates, and specifically to which version they are updating, 2.1 or perhaps 2.3. This is his answer:
I'm a bit confused now. Is software update to 2.1 different from ECU re-write?I’ve just checked with the master tech and he’s given me the impression that the updates you’re referring to below are the kind that auto install remotely?
The update we’re trying to finalise is the full rewrite of the ECU from the factory. The issue we’re having is that it gets so far through this update (which takes 10 hours in total!) then fails at a certain stage. We then contact the factory who provide us with fresh codes to use to get us to the next stage. Our technician was working on the car Friday and has updated VW and is currently waiting for a reply from the brand.
