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. www.openpresence.org/slk/K40-1.jpg www.openpresence.org/slk/K40-2.jpg www.openpresence.org/slk/K40-3.jpg the manufacturer has not acknowledged this problem and while the oed throws up repeatable codes once this part starts to deteriorate - P1420, P1236, P1235, and P1525, the mb dealer service centers have not been told about these codes and they tell customers that it is undefined and probably due to low batter voltage and send them with this problem still there until the problem gets big. If the customer is lucky, then it just results in a starting problem or stumbling but in some cases can result in loss of power while driving. This is the dangerous part. This part was redesigned in slks from 2001 onwards but the manufacturer has done nothing to fix this problem in earlier slks or to equip their authorized service centers to catch this problem before it creates a serious safety issue. My car is currently at the stage of having been misdiagnosed for the above codes.

- the contact owns a 1999 Mercedes Benz Slk230. The contact received a recall notice for the exterior lighting:brake lights. The Mercedes mechanic replaced the lights at the contacts home. Prior to replacing the lights per the recall, the lights were working. However, the lights no longer worked, and the vehicle did not start. The dealer did not want to address the failures and make the necessary repairs. The contact talked to the manager of Mercedes and he was unsuccessful at gaining assistance.

Brake light failure. I have had to change the complete socket numerous times. Each time the socket has melted. Mbusa tells me they know of the problem, but do not see any reason to fix it. Each repair runs about $300. I have had mine changed no less than 5 times in the past three years.
