“Electric cars don’t need servicing” is one of those half-truths that costs people money. It’s true that an i4 will never need an oil change, spark plugs or a fuel filter — BMW’s own maintenance documentation strikes those items out for its electric models. It is not true that the rest of the schedule disappeared with them.
Here’s what actually remains, and why some of it matters more on an electric BMW, not less.
What BMW’s own EV schedule includes
Strip out the combustion items and BMW’s condition-based servicing still calls for:
- Brake fluid — replaced every two years. It’s hygroscopic (absorbs moisture from the air), and time degrades it whether you brake hard or barely at all.
- Cabin micro-filter — typically every two years, same as any BMW.
- Brake inspection and clean — BMW’s electric-car scope specifically includes cleaning the pad contact points and checking disc condition, because regen braking leaves the friction brakes underused and prone to corrosion.
- Charge port and cable checks — inspecting the port’s pins and flap and the condition of your charging cable.
- Tyres — tread, wear pattern and pressures. EVs are heavy and deliver their torque instantly; tyre wear runs noticeably faster than on an equivalent petrol car, and uneven wear shows up alignment issues sooner.
- Underbody and battery tray inspection, plus a road test.
- Open recalls and software campaigns — checked against your VIN. Several BMW EV campaigns (battery modules, charging units, drive software) are VIN-specific, so this check earns its place at every visit.
On top of that, we test the 12V battery at every service. Yes, your EV has an ordinary 12-volt battery — it’s what wakes the car up and connects the high-voltage system, and a tired one is the single most common cause of an electric car that won’t start.
The bits people forget
Coolant. An electric BMW still has coolant — often several circuits, looking after the high-voltage battery, the drive units and the cabin heat pump. Condition and leak checks are part of a proper EV service.
Suspension and geometry. Weight is the enemy of bushes, springs and tyres, and EVs carry plenty of it. An annual look underneath catches wear early — exactly as it does on any car.
Time-based items on low-mileage cars. Plenty of EVs do short urban miles. Brake fluid, tyres and the 12V battery age by the calendar, not the odometer.
Why high-voltage qualification matters
Everything above the orange cables is a normal workshop job. The moment work involves the high-voltage system — battery, drive units, charging electronics — it needs technicians trained and qualified to BMW-approved high-voltage safety procedures, with the right equipment and isolation processes. Ours are, which is why i3s, i4s, i5s, i7s, iXs and every plug-in hybrid are all serviced in-house here, with nothing sent away.
The bottom line
An electric BMW needs less servicing — but not none, and not amateur hour. An annual health check alongside the MOT (first one at three years old), fluids and filters on their two-year clocks, brakes kept clean, tyres watched, software current. Do that, and an electric BMW is about the easiest car to own there is.
