- [513114](/bulletins/10148420.md), 2018-11-13, Service bulletin: EXTERIOR LIGHTING:HEADLIGHTS. Headlight Cleaning System: Functional Operation Change. The customer complains that the headlight cleaning system is not working properly and only works after several actuating attempts. CAUSE The "functional" operation of the headlight cleaning system was changed with integration level F020\-14\-07\-500. The functional changes to the headlight cleaning system's operation will occur only after programming the vehicle with ISTA/P 2.53.0 or higher. INFORMATION The headlight cleaning system is no longer activated with the first stalk activation when the lights are on. The functional programming change now requires the stalk to be activated four times before headlight cleaning is activated. The change prevents automatic activation of headlight cleaning when the customer only wants to clean his/her windshield. This is normal operation and no parts should be changed.
