Based on industry averages you can expect to pay between $3.49 and $15.19 for a Mercedes S65 fuel pump relay.
Where Is The Mercedes S65 Fuel Pump Relay Located?
The Mercedes S65 fuel pump relay sits either under the rear seat or in the trunk, close to the main fuse and relay panel. Mercedes sometimes tucks it inside a black, rectangular case, sharing space with a handful of other relays. You'll likely have to peel back some trunk liner or lift a cover to get a clear view. Each model year can place things a bit differently, so flipping open the owner’s manual is usually the quickest way to pinpoint the exact spot in your specific S65.
What Are The Symptoms Of A Bad Mercedes S65 Fuel Pump Relay?
When the Mercedes S65 fuel pump relay starts to fail, the car might show signs like sluggish starts, random power drops, or a flat-out refusal to start. Sometimes, you’ll turn the key and won’t hear the pump kick on at all. On the road, the engine could stall, often just as you accelerate or try to pass another car. A failing relay tends to cause more headaches the longer it’s ignored, with early symptoms often turning into a full-on no-start.
How Do I Test The Mercedes S65 Fuel Pump Relay?
To test a Mercedes S65 fuel pump relay, pull it out of its socket and grab a multimeter. Test the terminals for continuity; no reading probably means it’s bad. If you’ve got a similar relay next to it, try swapping them—if the problem moves, you’ve found your culprit. Always turn off the car and pop the battery cable before diving into any electrical work, just to keep things safe and avoid extra repairs from a simple spark.
Can I Drive My Car If The Fuel Pump Relay Is Failing?
Driving with a dying Mercedes S65 fuel pump relay usually leads to trouble you’d rather avoid. Maybe the car runs. Maybe it doesn’t. If it leaves you by the side of the road, there’s not much you can do besides call for a tow. When the relay cuts out while you’re driving, the engine can quit without warning, which could be risky in traffic. Best move: swap that relay at the first sign of a hiccup, so you’re not stranded or worse.
How Much Does It Cost To Replace The Mercedes S65 Fuel Pump Relay?
A Mercedes S65 fuel pump relay won’t break the bank. Expect to pay anywhere from $25 to $75 for the relay itself, depending on where you shop. Handing the job off to a shop can tack on $50 to $120 in labor, though swapping it yourself only sets you back for the part. AMG and rare trims may charge a premium for the piece, so have your model details handy when looking for prices.
