The overvoltage protection relay is responsible for the power supply to the control units and components of the KE-Jetronic injection system. Here you get a reproduction of the rarer 5-pin version for older vehicles, which is also installed in many Mercedes 190E 2.3-16.
Over the years, difficulties often arise – e.g. due to cold solder joints. In the event of idling problems and especially in combination with ABS or ASR problems, the OVP relay is one of the first suspects that should be checked.
A 9-pin OVP relay to replace the original 7- or 9-pin units from W201, W124 and other models can also be found in our store.
