I bought my used 2016 e-golf in Jan. I took the car back to the dealer due to a brake squeal and when I got it back, the mode button no longer worked and the display no longer showed the speed. The dealer said that they didn't do anything so it wasn't their problem (they aren't a VW dealer. Their techs have no clue how e-golf work). I just left it and hoped it would go back to normal but it hasn't. I am in Canada and my warranty is valid in the US until September, but the border is still closed so I can't do anything about it right now.
Does anyone know how to fix this issue? Obviously my range has decreased and is very frustrating.
