P2583 on Mercedes-Benz by model: symptoms, diagnosis and fix
On the W167 GLE (2020-2024), the front radar sensor behind the grille that feeds Distronic adaptive cruise control, Active Brake Assist and PRE-SAFE frequently faults, throwing 'Pre-Safe Functions Currently Limited' and disabling those safety systems. Code P2583 indicates the front radar is offline. Common causes are a dirty or snow/ice-blocked sensor, sensor misalignment after minor front-end impacts, and wiring/connector corrosion in the harness (W167 harness part A1675401443) near the right front bumper; a fault in the 48V system can also cascade into ADAS errors. The car remains drivable but loses automatic emergency braking and adaptive cruise.
Common Symptoms
- Pre-Safe Functions Currently Limited warning
- Distronic / adaptive cruise unavailable
- Active Brake Assist inoperative
- intermittent ADAS warnings
- radar sensor dirty message
How to Fix
Start by cleaning the radar emblem/sensor area in the grille and clearing snow, ice, mud or badge film, which resolves many cases. If the fault persists, scan for P2583, inspect the radar harness connector near the right front bumper for corrosion or broken pins and repair as needed, then have the radar recalibrated (or replaced if failed) with Xentry. Rule out 48V-system faults that can trigger ADAS errors.

Frequently asked questions
What does P2583 mean on a Mercedes-Benz?
P2583 stands for "Cruise Control Front Distance Range Sensor Single Sensor or Center." This code sets when the powertrain/cruise control module detects a fault or implausible signal from the front distance range sensor used by the adaptive cruise control (ACC) system. This sensor (radar or laser) measures the distance and relative speed of the vehicle ahead so the system can maintain a set following gap. When the fault is present, adaptive cruise control is typically disabled and a warning lamp is displayed. On Mercedes-Benz it is documented across 1 model: GLE.
What are the most common causes of P2583?
The most common causes of P2583 are: Front distance/range sensor obstructed by dirt, snow, ice, mud, or debris on the sensor face or grille, Misaligned front sensor (often after a collision, bumper repair, or grille work) requiring recalibration, Faulty or internally failed front distance range (ACC radar/laser) sensor, Damaged wiring, connector corrosion, or poor connection to the sensor circuit, Software/calibration fault or low system voltage affecting the ACC module, Aftermarket bumper, grille emblem, or accessories blocking the sensor field of view. The specific cause varies by vehicle.
How much does it cost to fix P2583 on a Mercedes-Benz?
Repair costs vary widely with the root cause and Mercedes-Benz model; each issue on this page carries its own estimate where one is published.
