I got some aftermarket dynamic side turn signals for my B8 last year and the left one always throws an error for electrical error in circuit. Loads of people have them and say they're error free so thought I might have a duff set. Ordered another and now both sides are giving errors. The warning beep fills me with fear nowadays so was wanting to code them out ideally - can this be done? A youtube video suggested 09 - cent elec coding - 07 Long coding helper Byte 18 and then bit 7 for side turn signals. Does this sound right?
