I have some Audi seats with heating and have picked up a used climate panel on eBay with the heated seat buttons. Does anyone know how much of a job it is to retrofit this and get it working? I have seen posts on full retrofit with the panel, loom and pads, but what about with non transported heated seats that already have heating module etc? Anyone done it? I have heard of possible component protection and coding needed but not able to find anything concrete. It was a cheap buy so worst case will sell it on but thought it was worth a punt as they don’t come up often.
