Where Is The Mercedes CLA250 Starter Relay Located?
Finding the Mercedes CLA250 starter relay isn't tough, but it’s easy to overlook if you haven’t searched for it before. You’ll usually spot it in the main fuse box under the hood, close to the battery or pressed against the firewall. Mercedes puts a layout diagram inside the fuse box cover, which helps a lot. Some model years tuck the relay a bit more to the right side of the engine bay. The exact location can shift with small changes between versions. If you can’t spot it right away, your owner’s manual will point you in the right direction. Popping it out only takes a tug with your fingers or a quick pinch from some pliers.
What Are The Symptoms Of A Faulty Mercedes CLA250 Starter Relay?
When a Mercedes CLA250 starter relay acts up, the car makes its complaints pretty clear. You might get a loud click, but then nothing happens when you try to start the engine. Some days everything is silent, and the car just won’t turn over at all. For others, you might have some starts that work just fine, mixed with sudden refusals. Once in a while, the lights on your dash glow as usual but the engine acts like nobody’s home. In all these cases, the relay likely isn’t sending power where it needs to go, leaving your starter stranded.
How Can You Test The Mercedes CLA250 Starter Relay?
You can test a Mercedes CLA250 starter relay at home if you have a multimeter or a test light. First, turn off the ignition and hunt down the relay in the fuse box. Pull the relay out, and check for electrical continuity between its terminals. Give it 12 volts and watch to see if the continuity appears between output terminals—if not, it’s probably bad. Another common trick is to use a known good relay from another system, maybe the horn relay. If the car fires up after the swap, you’ve found your culprit.
Can A Bad Mercedes CLA250 Starter Relay Drain The Battery?
A fried Mercedes CLA250 starter relay can occasionally steal current right from your battery. If it sticks in the closed position, it might sneak electricity to the starter or just pull small currents all day, even when the car is parked. This can leave you with a battery that fades away overnight. It’s not the usual way these relays fail, but it does trip up some owners and can lead to lots of head-scratching. If your battery keeps dying and nothing else makes sense, the relay is worth a second look.
What Is The Replacement Cost For The Mercedes CLA250 Starter Relay?
Swapping a Mercedes CLA250 starter relay won’t break the bank. Most relays run anywhere from $15 to $45 if you buy them yourself. Because you don’t have to take anything else apart, labor costs are almost nonexistent—just pop it out and pop the new one in. Even at a shop, you’re usually looking at $50 to $100 total, including the part. Doing it at home can save you even more. Most folks finish this job in under ten minutes and get back on the road.
