The door handles are similar in design to the E46
and pull out and upward for opening. Removal of
the handles is also similar to the E46.
There are no serviceable components on the
lock/latch. The assembly must be replaced as a
unit.
The lock cylinder is removed by removing the
torx screw through the access hole in the door.
Once the screw is removed, the lock cylinder can
be pushed out of the handle assembly.
The handle is removed by loosening the hex nut
holding the handle to the latch mechanism.
The handle is then removed by pulling it out and
down to release it from the latch. The handle is
turned down to the left to release it from the door
latch assembly.

Climate Control System (IHKA)
The IHKA is standard equipment on the X5 with the M62 engine and optional equipment
on the M54 version. The IHKA system is taken from the E39 sedan and includes all func-
tions and features of the IHKA currently installed in the E39.
Features of the IHKA system include:
• Integrated control panel/module.
• Separate temperature control for the driver and front passenger.
• Air flap control through the use of bussed stepper motors.
• Automatic Recirculation Control (AUC).
• Recirculation air flap control from the MFL.
• “REST” function for residual heat when vehicle is stopped.
• Service station feature that closes the water valves when stopped to prevent hot water
circulating into the heater cores.
• A/C compressor clutch activation through a final stage control.
• Center face vent stratification control through a bowden cable.
• Separate blower motor for rear passenger compartment
The rear blower motor is located below the center storage box behind the center air outlet
grilles. The blower speed control is mounted in the panel below the outlets. Cool or strati-
fied air is available at the center outlets.

EHC Service Information
Diagnosis / Coding
• The EHC control module is connected to the diagnostic link. The EHC control module
activates the fault display in the instrument cluster to alert the operator of the off-line sta-
tus of the system. The EHC control module stores up to three electrical/electronic
faults.
• Diagnosis/troubleshooting of EHC is carried out using the fault symptom troubleshoot-
ing program of the MoDiC or DIS. The EHC system has an extensive diagnosis program.
• Replacement control modules are shipped in the factory mode. The control modules
must be ZCS encoded using the DIS or MoDiC to activate the operating parameters.

DIS/Modic Service Funnction Program
The Service Functions program of the DIS/MoDiC provides the Transport Mode activa-
tion/deactivation and Ride Height Offset functions (see next page).
Once the transport mode has been released, or if the system requires left to right side
height adjustment, the ride height "OFFSET" must be carried out to ensure that the vehi-
cles suspension has a base ride height level starting point.
The "HEIGHT OFFSET" is adjusted using the DIS or MoDiC. The procedure is as follows:
• Place the vehicle on a level surface unloaded.
• Access the Height Offset program in the service function menu.
• Measure the base ride height from the lower edge of the wheel housing to the center of
the wheel hub.
• Check measured height against the specifications listed
• Use the DIS/MoDiC to correct the ride height if the value differs from the listed specifi-
cation.
