Clicking Noise from Off-board Charger. While the vehicle is charging, the off-board charger is clicking. The clicking noise comes from the relays inside the charger cycling off and on. This condition most commonly occurs when the vehicle is fully charged; it is plugged into the charger; and then pre-conditioning is activated via the BMW iRemote app. The cycling of the relays can last from a few seconds to several minutes. Despite this cycling, the vehicle will continue to charge and pre-condition normally. While this condition can affect any off-board charger brand (Level 1 or 2), the Clipper Creek HCSSeries (Level 2/240V) charger tends to be more susceptible. CAUSE This situation is caused by an EME software issue that allows, depending on the electrical load demand from the vehicle, the charging to cycle on and off excessively.
