Long story short, I plebishly slipped my foot off the accelerator and right into the (very close) car in front at the lights today. There was absolutely no damage to both vehicles surpirignly as I caught the brakes pretty quick but the tap has set off the bonnet raise warning light that should go off for pedestrians. Absolutely no visible damage as I say but I have read elsewhere on the forum about a thin metal sheet behind the bumper that calibrates this sensor. Anyone have any information on if this can be user reset or if the part can be recalibrate easily? Trying to rack the service manuals with no luck.
