Hello All ... First post. I have an intermittent buzz prior to, stopping at and continuing after start up which I initially thought came from the passenger side engine bay but now, after further investigation, seems to be immiting in the center of the dash up by the vents at the windshield. It hasn't been as loud as I initially said. As I said noise can happen prior to start up with ignition in on position. Performance hasn't seemed to be effected.
Air conditioning and 4wheel drive don't seem to be affected.
There seems to be a solenoid at that location in the engine bay attached to one of the turbo's tunnels. Could this be what is making the buzzing?
All help greatly appreciated. Thanks ... Dave
