Good advice so far, but there has to come a day where the vehicle is not fit for purpose and can be rejected.
I had this scenario with my Discovery. It was with the dealer for longing that it was with me, so in the end I rejected the vehicle. Shortly after rejecting it, they finally found the root cause and then offered me 4 x free services, considerable amount of dealer fit options (for me to choose upto a cash value) and other sweeteners.
However, for me, the damage had been done and I stuck to my guns and got a replacement vehicle, mainly because they'd pulled the entire front dash out and there was no way that was going back together again without high risk of squeaks and further issues.
The point being, consider what you want and don't be brow beaten into accepting the vehicle if you don't want it. It's harder with a Cali, as the lead times are so long, but it's far too much of your hard earned money to buy the vehicle to compromise on.
If you're happy with some compensation, then make sure it's generous and actually you feel happy with the offer. Say (and mean) that you are prepared to reject the vehicle unless they meet your requests. Once they realise rejection is your plan B, they will be most accommodating.
For what it's worth, Land Rover had to discount £9k + for my replacement vehicle, so it's their least preferred option by a long chalk.
