The reason why the steering wheel of Audi A6 cannot be adjusted up and down is: the power supply control unit J519 has not been set up or the basic setting operation is not standardized, and the fault is caused by incorrect power-off operation. When encountering this kind of fault phenomenon, the power supply control unit J519 of the offline vehicle can be correctly set. The setting method is introduced as follows: Turn off the ignition switch, disconnect all the plugs of the power supply control unit J519, and reconnect all the plugs after 5 minutes; use VAS5052 to enter the fault navigation menu, select the corresponding model, year, etc., and perform the vehicle system test; after the vehicle system test reads the fault memory, transfer to the test plan. Select "09" power supply control unit J519, recode it -112101. Then perform the basic setting (note to select the basic setting for replacing the vehicle power supply control unit J519, not the basic setting for replacing the steering column adjustment switch E167. At this time, the steering column should be able to adjust up and down and front and back; exit the system.
I previously had an issue with the up-and-down adjustment of the steering wheel on my Audi A6, which is quite common. The most likely fault is that the adjustment motor is stuck or burnt out, as Audi's electric adjustment system is relatively delicate and prone to wear over time. Another possible cause could be a blown fuse—the fuse box in the car is usually located near the driver's footwell, and you can check it yourself. Alternatively, there might be a loose wiring connection, such as a broken or corroded wire from the switch to the motor. For safety, avoid forcing the adjustment to prevent further damage to the system. I recommend going to a 4S dealership for a diagnosis first—they have professional tools to quickly pinpoint the issue. The repair cost may not be high, but don’t delay, as it affects driving comfort and safety, especially during long trips.
