Refinishing Park Assist Sensors: Rolls-Royce

Park assist sensors are part of the park assist system, just one of many advanced driver assistance systems (ADAS) found on vehicles today. Damaged sensors are typically replaced and may require painting to match the vehicle. Vehicle makers often provide information on the painting of new sensors. Some vehicle makers do not recommend refinishing sensors with minor finish damage because excessive paint thickness may adversely affect the operation of the park assist system. However, other vehicle makers allow refinishing and provide guidelines. Let’s see what Rolls-Royce has to say.

Rolls-Royce states within vehicle-specific repair manuals under the Functional Description ➤ Ultrasonic Sensors ➤ General Notes:

"Ultrasonic sensor must not be painted. This neither touching up nor complete painting."

Improper paint film thickness affects the functionality of the sensor. Review and follow OEM guidelines including warnings and notes within procedures.
