Ceri Posted July 26 Share Posted July 26 That's when the vvt motors shift. Ask you mechanic to activate them as a diagnostic test using techstream. Quote Link to comment Share on other sites More sharing options...
Jenny Smedley Posted July 26 Share Posted July 26 (edited) Probably not it, but last time we had a service the mechanic found a piece of paper in our air filter in the people heater/air access. Stopped our noise immediately, and it was odd like yours and was a rattling/ticking sort of noise. Worth a look?
