C0528 Steering Angle Sensor Module Range/Performance

C0528 means the module delivers an angle that is out of range or behaves implausibly while it still communicates. Audi documents it on the 2015–2018 A3 e-tron as C052800, steering angle sender with implausible signal, sometimes stored together with P060700 after ESC had been switched off (TSB 2060682/1); the ESC lamp lights. A Kelsey-Hayes patent shows how such checks work: an offset that moves more than 15° after re-zeroing counts as a shift fault, more than 10 s of cumulative dropouts or 1000 events as intermittent, and yaw control stays off until the signal is trusted again. Bosch builds plausibility tests between the measuring channels into its GMR sensor. Unlike C052A, the error lies in the sensor value itself.

Likely causes

Steering angle sensor module delivering implausible values
ABS/ESC module software issue (Audi A3 e-tron)
Offset after alignment or steering work without re-zeroing

Symptoms

  • ESC warning lamp on
  • Stability control unavailable or intervening at odd moments
