Looks like its the Ingenium petrol that's the main issue.

One bit jumped off the page...".The repairs could include software updates as well as physical alterations, and some Range Rover Evoque models will need new tyres, a JLR spokesperson said."

New tyres....wait...what?

On wonders if these wrong CO2 measurements could mean the cars have fallen into lower VED or other taxation bands than they should have.

Be interesting to see if the revised vehicles suffer performance or driveability issues after the fix.

Tyres/wheels presumably to be swapped for less rolling resistance? does the new emission testing system utilise a rolling road?

Perfectly possible - the Hyundai Ioniq/Kia Niro did this - the top spec car with 17in rims was over the limit for the low VED band and the lower spec ones on 16/15in rims were under.

LR have made the same basic error as some other makers, Honda for one, ignored and neglected those small c conservative bread and butter repeat customers who put them where they are (and provided a constant supply of used examples to attract the next generation of new buyers), leaving them without a decent reliable working product to buy even if they wanted to, chasing instead image and fashionistas.

The problems in China relate more to the local production line they have there.

Too much style and not enough (engineering) substance methinks.
