We bought my son a 500S to learn to drive in and it was woefully slow. We took it to our local dealer and they reflashed the ecu which made a difference. It was better for about a month and has gone back to how it was. It’s underpowered that we need second gear to get up the hill we live on and driving it is almost hard work. Does anybody know if there have been any updates in the last year? I don’t really want to pay for an hours labour to be told it’s up to date.
