Where Is The Mercedes Cla250 Fuel Pump Relay Located?
The Mercedes CLA250 fuel pump relay usually sits inside the main fuse and relay box. With most models, you’ll find this box under the hood along the passenger side, though some years tuck it closer to the passenger footwell. If you flip open the cover, there’s often a diagram stamped right inside showing which relay does what—no guesswork needed. Sometimes the writing is small or smudged, so a flashlight helps. The owner’s manual lays it out in more detail if the chart is tough to read. This relay is easy to overlook, but knowing exactly where it sits makes any diagnosis or fix less frustrating.
What Are Common Symptoms Of A Bad Mercedes Cla250 Fuel Pump Relay?
People usually first notice trouble when their Mercedes CLA250 fuel pump relay starts going out—the engine won’t fire up, or it cuts out when you least expect it. At times, you may try to start the car and get nothing but cranking. Some drivers report the car dying at a stoplight or stalling mid-trip. If you turn the key and hear silence from the rear, that’s another hint. Many see a check engine light pop on, sometimes flashing codes about fuel delivery. The symptoms rarely show up all at once, so if these annoyances start stacking up, check the relay.
How Do You Test The Mercedes Cla250 Fuel Pump Relay?
To test the Mercedes CLA250 fuel pump relay, pull it from the fuse box and grab a multimeter. You can check resistance between the terminals against specs in a repair guide. Some just swap it with an identical relay from elsewhere in the box—a trick that works fast if both do the same job. If the fuel pump buzzes with the swapped relay, your answer is clear. Take your time, follow the diagram, and test every connection. Rushing often misses simple problems, so be patient until you know for sure.

Swap the relay soon as problems show; driving with a weak relay isn’t worth the headache.
