I have also been researching diagnostic tools and came across this video. It supposedly does the suspension calibration but not customisation (which I am not bothered about)

Launch X431

&t=636s

Its about 130 quid

An interesting spot, especially when you see that the lister is Kingbolen in china not Hong Kong and also the manufacturer part number is "LAUNCH X431 V PRO V+ PROS MINI PRO3S+ PRO5 PAD THINKDIAG"

The more I investigate the more incestuous these companies become.

However the Launch is interesting as it implies in the listing that other brand software is available as well as JLR.
