Range Rover Evoque II Battery Drain: Why It Dies Overnight

If your Range Rover Evoque II is dead every morning, you’re not imagining it — a modern Evoque has dozens of modules that should go to sleep after you lock it. A parasitic draw means one of them, or a lamp, latch, or added accessory, is staying awake and sipping current. It’s a common complaint on these cars, and it’s very diagnosable with the right current-draw test rather than guesswork.

Likely causes. Start with the battery itself: an ageing AGM battery can test fine at rest and still collapse under load, especially in cold weather. After that, think modules and switches: a door, bonnet, or tailgate latch microswitch not reporting “closed”; interior or boot light staying on; a sticking fuel flap or glovebox light; the infotainment/telematics unit failing to sleep; an alarm or keyless-entry sensor triggered by a nearby key; or an aftermarket dashcam, tracker, or USB charger wired to a permanent live. Faulty BCM, gateway, seat, HVAC, or audio modules are also known culprits, often with related fault codes stored.

What to check first. Have the battery condition and charging system tested properly, then scan all modules — not just the engine — for faults and last-wake events. Next, do a measured parasitic draw test: lock the car, wait for it to sleep (often 30–60 minutes), and clamp the battery cable to see if current settles to roughly 20–50 mA. If it stays high, pull fuses one at a time or use voltage-drop testing to isolate the circuit, then check the latch switches, interior lights, boot light, infotainment, telematics, and any non-factory wiring. Don’t forget a second key left in the car or a phone charger left plugged in.

Is it safe to drive? If the Evoque starts reliably and shows no charging warning, a short trip to a specialist is usually fine — but don’t treat it as normal. Repeated flat batteries and jump-starts can upset modules, and low voltage can cause odd electrical warnings. If you see a battery/charging light, power-steering or brake warnings, or the car needs a jump start every day, avoid long trips and get it diagnosed promptly; a weak battery plus a draw can leave you stranded.
