1. What does B107BF0 mean?

Audi DTC B107BF0 with symptom 233479/233523 indicates temporary partial system availability caused by environmental influence, such as an external ultrasound signal, a street sweeper, or construction equipment.

2. Technical explanation

Audi manufacturer communications state that external influences—including dirt, ice, and external ultrasound signals—can cause the affected system to become temporarily unavailable to prevent false driver warnings. For B107BF0 symptom 233479/233523, the documented examples are external ultrasound signals, street sweepers, and construction equipment. The supplied evidence does not identify the exact system name.

  • Temporary partial availability of the affected system.

6. Possible causes

  • Environmental influence from an external ultrasound signal.
  • Operation near a street sweeper.
  • Operation near construction equipment.
  • The manufacturer communications also describe dirt and ice as environmental influences associated with B107BF0/B10FCF0, but the supplied B107BF0 canonical symptom is 233479/233523 for external ultrasound-related influences.
