I have a 2016 Mazda 6 2.2 skyactive Diesel Tourer.
Yesterday morning when I started the car there was a buzzing noise that sounded like a solinoid or relay trying to open, it buzzed 3 or 4 times, the engine started as normal and as I was about 20 miles from home I drove it, it drove perfectly normal, no loss of power or any indication of any issue. It was coming from the top of the engine, there was also a warning on the SCBS Forward Malfunction as well as the traction control light and the engine management light. Has anyone ever had a similar noise from the top of the engine. It's 3 or 4 intermittent buzzes on start up then normal driving...very straight.
Thanks
