Message I got a sound down that sound like a cricket. It there when the car is cold. Disappears at idle after the engine gets a bit warmer. I can rev the engine a bit and the sound comes at a certain low rpm range. I can't pinpoint from where. If under the car it sounds like it comes from button, turbo etc. From top it sounds like it comes from the the plenum. Maybe around the middle.

Dont know if it related but its due for a timing belt change. 30.000km and about 5-6 since last time.
