Hi just wondered if anyone can provide some help. My 67 plate Insignia B has had a new steering rack fitted due to a accident and has been taken to a Vauxhall Dealer as the steering rack needs to be programmed to the car. The Dealer has said they can’t do it as Vauxhall states a software update is needed. currently it says code mismatch. does anyone have any info or knowledge on this? thanks Jay
