LED bulbs will cause flicker on light up. |

Do you mean just on turning on the lights? |

Conor, the LCM will check the Cold monitoring and the Hot monitoring of all lights... This is why the lights flash on start up as the LCM send a small voltage through every bulb to check continuity and if you have LED bulbs fitted this voltage will send the LED beserk... |

It should only do it on startup for a second or two, and only if LED bulbs are fitted. You can stop it by turning off cold monitoring with a diagnostic tool, but again, only if LED bulbs have been fitted.

My 2012 Westminster 4.4 TDV8 has recently had a headlight flicker.. My lights are set to Auto, so when dark, they come on automatically, however, just over the past few evenings, the headlights will momentarraly flick off then back on again, they are off for less than a second, but on the dark small roads around here, it’s quite alarming when it happens...
