Regular maintenance checks of your vehicle's suspension system can help prevent C06AF. Keeping an eye on your vehicle's ride quality and addressing any unusual noises or handling issues promptly can also be beneficial.

What is C06AF?

The C06AF diagnostic trouble code indicates a problem with the vehicle's active suspension system, particularly related to the suspension height adjustment. This code is commonly encountered in vehicles equipped with electronic suspension control systems, such as the 2015-2019 Ford F-150 and various luxury models from brands like BMW and Audi. When the C06AF code is triggered, it means that the vehicle's onboard computer has detected an issue with the height sensors or the control module responsible for adjusting the suspension. The implications of this code can range from decreased ride comfort to compromised vehicle handling. If left unaddressed, a malfunctioning suspension system can lead to uneven tire wear and potentially impact safety by affecting how well the vehicle responds to road conditions. Immediate attention is recommended, especially if you notice any handling issues or warning lights on your dashboard. Ignoring this code could lead to more severe suspension problems down the line, making early diagnosis and repair crucial for maintaining optimal vehicle performance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C06AF is present:

  • Check engine light stays on constantly, indicating a malfunction in the suspension system.
  • The vehicle feels unsteady or bounces excessively over bumps, causing discomfort during drives.
  • The ride height may appear uneven, leading to a noticeable tilt or lean to one side.
  • A decrease in fuel economy due to improper vehicle alignment caused by suspension issues.
  • Unusual noises such as clunks or creaks when driving over uneven surfaces.

Possible Causes

Most common causes of C06AF (ordered by frequency):

  1. Faulty height sensors - 40% likelihood. These sensors can wear out or become damaged, leading to incorrect height readings.
  2. Defective control module - 30% likelihood. The control module may fail, preventing proper communication between the sensors and the suspension system.
  3. Wiring issues - 20% likelihood. Damaged or corroded wiring can interrupt signals between components, triggering the C06AF code.
  4. Air leaks in air suspension systems - 5% likelihood. If your vehicle uses air suspension, leaks can cause height inconsistencies.
  5. Software glitches - 5% likelihood. Occasionally, a simple software update may resolve temporary issues causing the C06AF code.
