remodel eco up! to ASG?

Hello guys, after my beloved VW Lupo TDI 3L was recently deformed so cold by an Opel-Vectra driver (no clichés…) that a repair is no longer worth it, I love it with a VW eco up! The car would be perfect if – as the Lupo TDI 3L used to do – it had an automated manual transmission. However, according to VW car dealership this option is not available ex factory, although you can order the same engine variant without natural gas drive with ASG switch box… White jeman d, how costly or expensive a subsequent conversion could be? P.s.: Please save comments like “that’s not worth it” or “buy yourself a different car”. It’s primarily about the technical feasibility and an approximate financial house number. Always good ride for 2014 wishes you medialex
