Air Supply System (LVA)
The air supply system is identified as the LVA in the diagnosis program and in the repair
manual. It is mounted in the spare tire well compartment. The components are housed in
a sound deadening carrier, through rubber bushings, to prevent operating noises from
being transmitted through the vehicle’s interior.
With the exception of the compressor relay, individual replacement parts for the air supply
system are not available. If diagnosis determines a defect in any of the other air system
components, complete replacement is necessary.
The air supply system consists of the following components:
• Compressor assembly with;
- Piston compressor
- Electric motor
- Air dryer (desiccator)
- Pressure relief solenoid valve
- Pressure maintenance valve
- Check valves
• Compressor Relay (Replaceable)
• Solenoid Valve Block (2 - two way valves)

Power Distribution
The maintenance free 90 AH battery
in the X5 is mounted in the rear below
the spare tire and EHC compressor
unit. The battery box is formed of
molded plastic and the positioning of
the battery aids in weight distribution.
As with all BMW vehicles, the battery
is equipped with the BST on the pos-
itive battery cable.
Power distribution for the vehicle and
systems is through two fuse carriers
mounted in the right storage com-
partment in the rear and above the
glove box in the front.
The battery jump/charge point is
located in the engine compartment on
the left side of the fire wall.
