Scan the entire vehicle. Do not just look at the engine module. Read the codes from the ABS/ESP control unit and the ACC (Distance Regulator) module . Make a note of all present codes, not just DF357. For example, a DF001 code alongside DF357 strongly suggests a power supply or voltage issue.

If the problem persists, the next step is a physical inspection. Scan the entire vehicle

In transmission or hydraulic sensor modules, hot oil becomes thinner. If internal seals or pressure solenoids are worn, this drop in viscosity prevents the system from maintaining necessary hydraulic pressures, triggering safety faults.

Read live sensor telemetry while the vehicle transitions from cold to hot. Make a note of all present codes, not just DF357

The most frequent culprit is a failing brake pedal switch located directly above the brake pedal arm.

Tackling this code requires a systematic approach. Here is a proven path based on owner experiences.
