2 Electrical System problem

Failure Date: 02/23/2010

Hello, this is a pre-emptive report of a problem with a component in 1998-2000 mercedes-benz slk 230 roadsters. The failure of this component has many symptoms but one serious symptom is complete loss of power at highway speeds which can be dangerous. I am hoping that you don't actually have to wait for crashes and deaths before you investigate. I ask that you consider the documented problem here and see the potential for a serious safety issue and ask the manufacturer to address it. The problem arises from a poor design/manufacturing of soldering on a k40 relay module which is an electronic component and part of the electronics of the car that controls the engine operation. Certain soldered points have a tendency to get corroded/burnt out over time that affects the engine operations. The three pictures below show the affected part, the pcb inside and a closeup of the soldered joints that show the problem. . Read more...
