comment: today one of my DMEs started to smell burned and when I opened it, it showed that a component (transistor ?) is burned. See attached pictures. Do you know what this component does and the number/type? I thought maybe I can repair it.It happened just after I used INPA to check the DMEs Lambda values. I also tried to activate the lambda sensor heater and fuel valves from INPA before I started the car and I wonder if this maybe caused the damage. Before I started the car, I removed the plastic cover to check the lambda sensor heating relay that sits next to the DMEs, that's how I immediately noticed the smell and saw some smoke. I know this box is air-cooled but I can't imagine that this caused the fire.
