Just got a the car's first AC recharge since new (18 years...). Data may be helpful:

'07 NA base, uses Denso AC system. Recharged using standard R134 recharge system.
Pre-recharge system pressure from HVAC controller: ~130 psi.
Post recharge pressure from HVAC via OBD: Avg around 170psi, ranging up to >200 psi (when braking)
Post recharge Evaporator temp: 42 deg F
R134A Recharge amounts: 230 grams in system, recharge up to 700 grams.

Point is you can check your AC condition with a OBD reader. I used the Autel AP200 with JLR download, live data from HVAC controller.

BTW, my info is never use the recharge cans. Correctly done system vacuum/recharge is about $100-120 or so.

A note: this is a very typical AC system -- nothing unusual about it. Only thing specifically "Jag" might be the programming in the system controller. Any competent garage with a machine should be able to do it.

Hope this helps.

 

Clarification:

Note that system pressure varies by demands on system.

If it's 70F (21C) outside, and you want 70F inside, it may display 125-140 psi at the HVAC controller data readout.

If you're at 85-90F (26-32C) outside and you want 70F inside, it might operate at 170-200+ psi.

Point being, if you see 130 psi at 80F, you may need a recharge.
