Looking for some advice please. I have a 420d convertible and have had some coding done remotely. I now have the cable and laptop with the software installed.
I am wanting to update the 8 speed auto box to shift smoother and quicker?
I have searched in vain for an answer, will me adjusting this will it affect my previous coding done remotely? Or will it have to be done again?
Never done it before just wondering if it's worth doing?
Many thanks
