Darren Arcari Posted November 12, 2023 Share Posted November 12, 2023 Hi all, recently lost my undertray was only hanging on with 2 screws, after taking it at roadside as it was trailing the ground my A4 B8 now make a loud grumbling noise but only at 40mph or over can you tell me if I get the undertray put back on would the noise disappear?
