WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1: HIGH AND LOW PRESSURE SYSTEM PRESSURES UNSTABLE TEST 1 
    1. If the approved Jaguar Land Rover equipment gauges are fluctuating excessively, then the refrigerant may be contaminated with water.

    Did the pressure gauges fluctuate excessively when the air conditioning was set to off?

    Yes:  The refrigerant may be contaminated, for example with water. Using the Jaguar Land Rover approved equipment, complete a prolonged evacuation of the refrigerant and install a new receiver drier desiccant bag, if available. If a desiccant bag is not available, install a new receiver drier, or receiver drier and condensor if they are only available as a single component. Recharge the air conditioning system with nitrogen and confirm the gauges are stable. GO to PINPOINT TEST A 

    No:  GO to PINPOINT TEST G .
