Where Is The Mercedes CLS55 Fuel Pump Relay Located?
Tracking down the Mercedes CLS55 fuel pump relay can feel confusing if you haven’t done it before. For most CLS55s, you’ll find the relay tucked inside the rear trunk fuse box, passenger side, hidden behind a side trim panel. Some variants hide the relay up front under the hood in the right-side fuse block. Always double-check with your owner’s manual to be sure. If your fuel pump falls silent when you turn the key, that’s when you’ll want to look here first.
What Symptoms Indicate A Bad Mercedes CLS55 Fuel Pump Relay?
When the Mercedes CLS55 fuel pump relay goes bad, the signs rarely hide for long. The car won’t start, or it may crank extra-long before catching. Sometimes you’ll notice stalling while driving, or the engine just quits out of nowhere. No hum from the pump when turning the key is another tell. Relays can fail off and on at first, so problems may come and go before a total shutdown. If the car acts like it’s got spark but won’t stay running, take a hard look at this part.
How Can I Test A Mercedes CLS55 Fuel Pump Relay?
You don’t need fancy gear to test your Mercedes CLS55 fuel pump relay. Pop the relay out, then use a multimeter to run a continuity check between the pins. If you feed 12 volts across the coil terminals, you should hear a solid click as the relay moves. No click, or no connection in the meter, and you’ve likely found your problem. Always disconnect your battery first to keep things safe.
How Much Does It Cost To Replace The Mercedes CLS55 Fuel Pump Relay?
Replacing your Mercedes CLS55 fuel pump relay won’t break the bank. Expect to pay between $20 and $50 for a brand-new relay. If you handle the job yourself, your only expense is the cost of the part. Shops charge extra for labor, but honest repair pros shouldn’t need more than a quick visit, since access is simple and no special tools are needed. Many owners prefer changing it on their own to save even more.
Can Mercedes CLS55 Fuel Pump Relay Cause Engine Performance Issues?
People often think a relay either works or it doesn’t, but a flaky Mercedes CLS55 fuel pump relay can make your engine sputter or stall while driving. One moment the car runs fine, the next it coughs or dies. After a cooldown, it might restart—until the next glitch. If your engine skips or loses power now and then without clear cause, consider the relay a likely suspect before chasing bigger problems.
