This may sound crazy, but did the new headlight switch have an effect on the pre collision assist chiming a warning when you get too close to a car? Mine seemed to stop doing it after I got the new switch; yet it did chime a number of times on my way to the dealer today, on the congested hwy.
Can you please post the part number of the new part? The number I currently have is M2DZ11654GB. Do any of you know if this is the superceding part number or the number of the old switch?
