@Rich44 5.2 has been in MY24 builds for a while now, I beleive I also saw a post on the FB group with a new owner getting 5.4
There are 100’s if not more 80 & 60 owners who have been promised the upgrade to 3.7 but it’s taking months if not longer and in a some cases even when being done at a dealer it’s bricked the car 🙁
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
