Based on industry averages you can expect to pay between $9.39 and $34.99 for a BMW 735i turn signal relay.
Where Is The BMW 735i Turn Signal Relay Located?
The BMW 735i turn signal relay sits tucked away, out of sight—sometimes under the hood on the driver’s side, other times behind the dash inside the car. This spot depends on the model year, and BMW didn’t always pick the same location. Open the relay or fuse box and look for a guide on the lid or nearby. If the car’s still got its diagram, that should point you right to it. No luck? The service manual for your year will tell you exactly which one is the turn signal relay. If nothing’s labeled, you might end up matching numbers or tracing wires to be sure you’ve got the right piece.
How Can I Tell If My BMW 735i Turn Signal Relay Has Failed?
Your BMW 735i turn signal relay might be acting up if your turn signals never blink, stop mid-blink, or go rapid-fire when they shouldn’t. Sometimes there’s dead silence from the dash when you flip the lever—no familiar clicking at all. You might notice one side acts up but the other’s okay, or maybe both sides flicker like a haunted house. Don’t forget to check the bulbs and fuses first. A bad relay isn’t the only reason your lights go on the fritz. If you’re unsure, swap the relay with another from the fuse box or grab a multimeter to test it.
What Causes The BMW 735i Turn Signal Relay To Fail?
Relays aren’t built to last forever. In a BMW 735i, years of use can wear out the contacts inside. If moisture sneaks into the relay box, corrosion can kick in. Wiring problems or shorts can spell trouble for the relay. Odd fixes after a fender bender—or anyone rewiring for new gadgets—sometimes bring unexpected headaches. Old age and relentless bumps in the road can crack solder joints, so the connection flickers or fails altogether.
How Do I Replace The BMW 735i Turn Signal Relay?
First off, pop the hood or slip under the dash—wherever your relay box is. Always disconnect the battery before you start. Find the relay using the lid’s diagram or reference guide. Pull the dead relay straight out. If it’s stubborn, use a relay puller or gentle rocking. Pop in the replacement, making sure it clicks right in and sits firm. Cover everything back up and reconnect your battery. Turn on the signals for a quick check. Most jobs like this wrap up in less than twenty minutes—even if you’re not a mechanic. Double-check no loose wires or wobbly relays before you button it up.
Are There Differences Between OEM And Aftermarket BMW 735i Turn Signal Relays?
Pick OEM if you want to avoid guesswork—fit and function come factory-tested, though you might pay more. Aftermarket relays are a cheaper choice, but quality can swing wildly. Some work exactly like the original, others fall short or fit poorly. Sourcing OEM for older cars sometimes gets tricky, so drivers often turn to aftermarket options out of necessity. No matter which route you go, check the part number twice and make sure it matches your model’s production year.
