Coding

Note #1: Coding is accepted after a specific login has been carried out.
Note #2: After successful coding the steering angle sensor basic setting needs to be carried out.
Note #3: Special Coding 04499 is used for BFB Engine with 1LT Brakes and Multitronic.

Basic Setting

Steering Angle Sensor (G85) Calibration

Before starting the procedure turn the steering wheel at least 30 ° left and back straight ahead.

[Meas. Blocks - 08]
Group 005 Field 1 (Steering Angle Sensor -G85-)
Specification: 0.0 °
Tolerance (when straight): ±5.0 °
[Done, Go Back]

Special Notes

Some of the Bosch 5.7 modules will not show live Steering Angle Sensor (G85) readings after the Login and Coding are performed. If this is the case -2.5 ° may be stuck in Measuring Block 005 and will not change when the wheel is turned. Make the wheels as straight as possible and continue with the Steering Angle Sensor (G85) Calibration.
