How to Remove the OVP on a 190E Mercedes

1. Move the vehicle onto a flat work surface. Place the car in park. Shut the engine off and apply the parking brake. Open the hood of the vehicle.
2. Find the OVP relay. Its box casing is made of black plastic and is next to the car battery.
3. Take off the OVP's cover. You'll see a 10-amp fuse that leads to the relay. Remove the OVP by taking out the fuse.
