Everest Battery Drain

My 2020 Ford Everest diesel is showing a discharged battery. Speedometer error, weak headlights, error codes, and struggling to turn over. With 158402 km, I suspect the battery sensor is draining the battery at rest. Anyone seen this?

Summary of the thread

A 2020 Ford Everest diesel was experiencing a discharged battery, speedometer error, weak headlights, error codes, and difficulty starting. The initial suspicion was that the battery sensor might be draining the battery at rest. After checking the alternator to ensure it was charging properly, the focus shifted back to the battery sensor. A technician confirmed the battery sensor was the issue, and replacing it resolved the battery drain problem.

Woah there, slow down! A discharged battery, huh? Sounds like you've been burning the midnight oil diagnosing this thing. Before we jump to battery sensors, you gotta check the basics. Is your alternator charging properly? Think of it like this: the battery is a bucket, and the alternator is the tap filling it up. If the tap's broken, the bucket's gonna be empty no matter how new it is. Get a multimeter and check the voltage while the engine's running. Should be somewhere around 14 volts. If it's lower, your alternator might be the real villain here.

Thanks for the quick reply. I'll check the alternator first. If it's delivering the right voltage, should I still look for parasitic drain, or could the sensor still be the problem?

Alright, alright, so the alternator's doing its job. If you're still getting those error messages and the battery's draining, yeah, that battery sensor thing you mentioned could be the culprit. Honestly, chasing electrical gremlins is a pain. Unless you're really comfortable with wiring diagrams and multimeters, best bet might be to take it to a workshop. They've got the fancy equipment to pinpoint the exact problem without you spending days pulling your hair out. Could save you a ton of time and frustration, you know?

Thanks for the help. A technician confirmed it was the battery sensor. Replaced it, and that fixed the battery drain. Cost 315€ for the part and labor. Appreciate the guidance!
