Got a 2003 530d sport with nav and all the gadgets.
Used carsoft 6.5 for the first time to reset the dash language from French to Uk English. Abandoned the E39 'vehicle coding' write first time round then did it again to completion. Now my language is english but the rev counter doesn't work, the mpg guage is a bit random and the OBC doesn't work.
Have tried repeating the process, guess I can't undo it.
On the bright side the language is still uk english, but there is so much else not working.
Any ideas ?
