Hi, for over a year I have a worrying clicking/ ticking noise coming from under/ front of a car when driving. Especially when driving along concrete barriers on dual carriage roads or in tunnels for example, seems like the noise is present at all times over 15/20 mph and the hotter the car gets or weather outside the more audible it gets. Let me start by saying that there is nothing in the tyre thread, it almost sounds like a stone stuck in the tyre. The tyres has been replaced along with all the brake pads and rotors, the suspenssion has been checked by my mechanic, no dice. What I have noticed is that going over things like joints of the bridges or slight holes in roads makes to noise appear or disappear and turning left while driving makes is more audible but correcting of the sterring wheel to the neutral position can make it go away and turning again makes it re-appear. I cannot hear it inside of the car with windows closed only when the window is opened. It worries me a lot because no one seems to have an idea what is it. Any information what it might be will be valuable, I drive an E Class Coupé from 2014.
Thank you.
Thank you.
