Vehicle Information
Condition
The customer may report that the Easy Entry function of the power adjustable steering column intermittently does not work.
Technical Background
The Easy Entry system is a standard convenience function of the power adjustable steering column. When the Easy Entry feature is
turned on (Figure 1, B pressed in), the steering column moves to the parked position after the ignition has been turned off and the key has
been removed. The parked position provides more room between the driver and the steering wheel. When the ignition is turned back on,
the steering column returns to the last stored position.
The steering column's position is stored in the memory of the vehicle electrical system control unit, J519 (address word 09).
The seat memory (optional equipment) also stores the steering column's position in the memory seat / steering column adjustment control
unit, J316 (address word 36), and is independent of the vehicle electrical system control unit.
During the Easy Entry process, the driver may unknowingly influence the last stored driving position in four different ways:
^
If the driver inadvertently touches or bumps the adjustment knob (Figure 1, A) and moves the steering column when exiting or entering
the vehicle, the new position is then stored as the last driving position in the vehicle electrical system control unit. The next time the
ignition is switched on, the steering column will only change position slightly or not at all, appearing as if the Easy Entry position wasAudi A8L Quattro Sedan (4E8) V8-4.2L (BVJ)

^ After removing the key from the ignition switch, the customer operates one of the electrical system components (the radio, for
example) when the electrical bus systems have entered sleep mode. When the electrical bus systems are awoken without the ignition
switch turned on, the current position of the steering column is then stored as the new driving position before the electrical bus
systems return to sleep mode.
^ The memory may be lost due to the battery not being completely charged (vehicle parked fora long period, aging battery, etc.).
^ If the vehicle is aging and has a weak battery, convenience functions are switched off when more power is needed to ensure that the
engine starts correctly. The Easy Entry function will appear to not function.
Production Solution
Not applicable.
Service
Instruct the customer to re-program the desired position of the steering column or to use the seat memory button (if available) to return
