This was the first thing I did when I got my brand-new 2023 HEV (73 plate) from the dealer; there was a lot of discussion on the subject on the forums back then. It worked good, although I also saw a little misalignment towards the summer's conclusion.
They refused to take any action because my VIN wasn't listed in the production run, even though I enquired about it during the 2-year servicing in November.
I didn't care to investigate it because, to be honest, it's barely perceptible, and winter is here. Would it be possible to have a second look once it warms up? 🤪
