Hi All, My 2009 1.33L Yaris has started to make a noise when starting from cold (see video attached). This only happens after it's been left for a few hours, i've done an oil and filter change with genuine parts and it has made no difference. Also it usually lasts a second or two longer than what i've recorded in the video, maybe it's better now because of the warm weather. What do you think could be causing it? Ross.
