OEM ADAS Radar Optimized Color Resources: Mercedes-Benz

Posted on 05 June 2024 Print

Changes in advanced driver assistance systems (ADAS) radar technology are introducing new refinishing considerations. We know that paint film thickness can affect the performance of ADAS radars, but color formula selection may also be a contributing factor. What resources do repairers have available? Let’s see what Mercedes-Benz has to say.

Mercedes-Benz provides an Information On Painting Bumpers With Radar Sensors document which has precautions pertaining to factory colors approved for refinishing operations. This document has a list of paint codes which are approved for refinishing bumper covers. This document is found under: 98 Paintwork ➤ General Notes: Passenger Cars: Paintwork ➤ Information On Painting Bumpers With Radar Sensors.

Mercedes-Benz states:

  • "The new, primed bumper can only be painted once with base coat and clearcoat for non-approved paints on vehicles with code 233 (Autonomous Intelligent Cruise Control Plus (Distance Plus))"
  • "The new, primed bumper may only be painted once with base coat and clearcoat on vehicles with code Z01 (Special paintwork) or code Z98 (Painting outside of paint chart) and code 233 (Autonomous Intelligent Cruise Control Plus (DISTRONIC PLUS)), code 234 (Blind Spot Assist) or code 507 (Remote-controlled Parking Premium)"
  • "The diagnosis radar beam damping must be performed using the XENTRY diagnostic system after the bumper is painted on vehicles with code 233 (Autonomous Intelligent Cruise Control Plus (DISTRONIC PLUS))."

Improper color selection may cause ADAS to malfunction and potentially fail. Check OEM repair information to identify what restrictions may apply to the repairs you are considering. Always verify that the ADAS is functioning properly after completing repairs.
