The average cost of a Mercedes E63 starter relay is between $3.49 and $12.59.
Where Is The Mercedes E63 Starter Relay Located?
The Mercedes E63 starter relay hides out in the fuse box, usually somewhere in the engine bay. Pop the hood and check the passenger side near the firewall. Sometimes, Mercedes shifts it inside under the dashboard, close to the pedals. Open the fuse box cover. There should be a diagram tucked inside—trace your finger until you spot “starter relay.” If you don’t see it, flip through the manual or a repair guide. Always turn off the ignition and pull the key before messing with fuses or relays.
What Are Typical Symptoms Of A Faulty Mercedes E63 Starter Relay?
With a bad Mercedes E63 starter relay, you’ll often hear a clicking noise, but the engine won’t turn over. Some days, the car might start just fine; other days, nothing happens. On rare occasions, you might see your lights flicker or lose power to the radio, but that’s less common. If the battery’s strong and everything else checks out, but you get no action from the starter, suspect the relay. These symptoms can be frustrating and sometimes overlap with a bad starter or loose wiring, so check all options before replacing parts.
How Can I Test The Mercedes E63 Starter Relay?
To test the Mercedes E63 starter relay, pull it from the fuse box. Swap it with another relay that matches—something non-essential like the horn. If your car starts, the relay’s shot. For a deeper check, grab a multimeter. Go across the pins and look for continuity. No beep, no continuity, it’s cooked. If you can, put 12 volts to the relay’s coil—listen for a solid click. No sound, no function. Don’t want to risk it? Take the relay to a shop or ask for help.
Can I Bypass The Mercedes E63 Starter Relay Temporarily?
It’s possible to bypass the Mercedes E63 starter relay in a pinch. Use a jumper wire to bridge the relay terminals, but only for a test—not for daily use. Bypassing can help prove the relay’s the issue, but using this long-term isn’t safe. It can fry wiring or cause greater damage. Swap the relay as soon as you can. The bypass trick is just to get you moving or confirm your diagnosis.
What Causes Mercedes E63 Starter Relay Failure?
A Mercedes E63 starter relay fails over time from dirt, age, or moisture slipping in. Electrical spikes from old batteries or shaky wiring also wear it out. Sometimes, it’s just random luck or one too many short drives—the kind where you’re always stopping and starting. If you go through relays often, look for leaks or check the battery and wiring. Something else may be wearing the relay down too fast.
