Hi all I know their are old threads on this but none clears enough to my non mechanical brain to work out. I’m really hankering for more performance and know a remap is a no no for warranty. Ive looked through the threads and other sites and seen reference to a JB1 tuning box. Other sites say tuning boxes are now detectable by VW brands including Seat and flash a TB1 code. This all puts me off as I worry about losing my 18 months of warranty if anything goes wrong. However, it seems the JB1 is the only tuning box not detectable. Anyone able to confirm this and if true, for a non mechanical person is it easy to fit/ remove for service. Waiting to the end of warranty I’d becoming unbearable! Cheers for the help.
