Ticking Noise Under Hood (Video)
What is this ticking noise(!?):
Just started hearing tonight! In the second clip, it’s there, increases in intensity, then stops, but returns... Last edited by dbs600; 05-08-2013 at 12:47 AM.. |

It's normal. It's caused by the higher pressure fuel injectors our direct injection engines now use. MB, Cadillac and all direct injection engines have the same loud ticking. It's a common side effect. Search google for direct injection ticking noise and you'll get plenty of detail.

Thank you, Gentlemen. I understand the baseline noise is due to the direct injection setup, but I'm referring to the noise that goes away; it's a very loud ticking noise – not the baseline ticking that's constant throughout...
