Mini Cooper S 2003 - Software upgrade
Hi, I have been told today after my car having a diagnostic check for loss of power code P1688 possible by pass valve, that I should upgrade my software. I have been quoted £100.00 is this about right or is this price way too high, also is it essential that I have the upgrade or is this just a sales ploy to get more money out of me. Is it recommended as I am not sure I can afford both the replacing of the by pass valve and the upgrade, however if it is essential then I will try and find the money and go for it.
Any advice would be appreciated
