My 2016 4/4 that I sold developed a misfire and the engine light came on, this was about 18 months after the new owner took it on. He didn’t notice the issue straight away as the car had been sitting in his garage and hadn’t been driven for a while. He eventually decided to put it up for sale on SOR with Brands Hatch Morgan and it was BHM who diagnosed the fault to the printed circuit board behind the dash, it was damaged, and likely due to water ingress or heat and needed replacing. In the end the factory did the repair and it had to be recoded. Think it was called a coded binnacle, I know it wasn’t cheap.
