Power Steering System Squeaking Noise Repair Procedure AFFECTED VEHICLE RANGE CONDITION SUMMARY: POWER STEERING SYSTEM SQUEAKING NOISE Situation: On some S-Type, X-Type and XJ Range vehicles within the VIN ranges above, a squeaking noise may be apparent from the power assisted steering system when the steering wheel is rotated in either direction. The noise is caused by a seal inside the steering rack. The noise can be transmitted through the steering column and steering wheel, making it difficult to diagnose. This bulletin does not address any other PAS noises, such as pump or drive belt related noises. Action: In the case of a verified customer complaint matching the description above, refer to the Repair Procedure detailed in this bulletin and complete the service fix.REPAIR PROCEDURE PAS SQUEAK/FLUID ADDITIVE Open driver’s door. Ensure the gear lever is in either neutral or park, the parking brake is ‘ON’, and the ignition is ‘OFF’. Open hood and install fender protectors. 4. Remove the power steering fluid reservoir cap (and filter mesh on XJ and S-Type vehicles) and ensure the fluid level is correct. (Figure 1) 5. Using a suitable clean syringe, remove 50 ml of steering fluid. NOTE: The fluid additive must only be added once and the supplied label must then be affixed to the power steering fluid reservoir. 6. Replenish the power steering fluid reservoir with 50 ml of the specified fluid additive (C2S 48887). 7. Affix the supplied label to the power steering fluid reservoir NOTE: Suitable temperature reading equipment must be positioned into the power steering fluid reservoir, (filter mesh must be removed on XJ and S-Type vehicles) and that the temperature can be read while carrying out the heating process. 8. Insert the temperature reading equipment probe into the power steering fluid reservoir (about halfway into the depth of the fluid). HEATING THE STEERING FLUID TO 100°C +/- 5°C (212°F +/- 10°F) 1. Turn ignition ‘ON’ and start the engine. With the engine idling, turn the steering wheel from lock to lock four times to cycle the fluid additive into the system. (Figure 2) CAUTION: Under no circumstances hold the steering wheel on full lock while heating the steering fluid (to avoid damage to the steering system). CAUTION: While carrying out the following procedure, ensure that 105°C (221°F) is not exceeded. 3. While stationary and with the steering wheel in the center position (road wheels in the straight ahead position), turn the steering wheel 90° (quarter turn) right and hold firmly with both hands. (Figure 3) ^ Increase the engine speed to 3000 rpm. ^ Monitor the power steering fluid temperature until 100 +/- 5°C (212°F +/- 10°F) is reached. PERFORMING THE STEERING MANEUVER NOTE: The steering maneuver should be carried out on a hard flat surface outside of the workshop. CAUTION: Do not hold the steering wheel on full lock for more than two seconds as this may cause damage to the steering system. 1. Verify the power steering fluid temperature is at 100 +/- 5°C (212°F +/- 10°F), engine idle speed set between minimum 900 rpm and maximum 1000 rpm. 2. Turn the steering wheel to full lock and hold for two seconds.

ISSUE On some 2002-04 MY X-TYPE vehicles within the above VIN range, customers may have concerns with the vehicle interior fogging or the climate control cooling the vehicle slowly. The concern may be caused by the air inlet blend door being loose on the actuator shaft. ACTION In case of a customer complaint of the above condition on a 2002-04 MY X-TYPE vehicle within the above VIN range, first test the operation of the air inlet blend door. Set the fan speed to MAX and manually de-select the recirc button, there should be an audible difference in the climate control temperature motor noise. If the volume stays the same then the air inlet blend door is suspect. To rectify follow the workshop procedure outlined below. WORKSHOP PROCEDURE 1. 2. 3. 4. 5. 6. Open door. Turn ignition ‘ON’. Operate front seat fully rearward for access. The air recirculation switch should be in the fresh air mode. Turn ignition ‘OFF’. Remove the glove compartment hinge retaining screws (Fig. 1 ).7. Remove the glove compartment retaining screws (Fig. 2 ). 8. Disconnect the glove compartment lamp electrical connector (Fig. 3 ). 9. Remove the glove compartment. 10. Disconnect the air inlet blend door actuator electrical connector, undo and remove the climate control upper front stepper motor securing screws and displace the climate control stepper motor and reposition to gain working access (Fig. 4 ).
