F70 · 2024–…
On sale since October 2024, the 120d pairs the 118d’s 110 kW diesel with the 48-volt system. BMW quotes 120 kW in total: compare with your registration document, which may also show 110 kW. An oil change takes 6.5 l.
Figures apply to the cited configuration and market; equipment and transmissions may vary by production date.

1,995 cc four-cylinder diesel (ADAC engine code B47C20B): 110 kW (150 hp) between 3,750 and 4,000 rpm and 360 Nm between 1,500 and 2,500 rpm, plus 15 kW and 55 Nm from the electric motor, for 120 kW (163 hp) and 400 Nm in total. Two-stage turbocharging (high- and low-pressure, variable geometry), 2,500-bar common-rail injection. Exhaust treatment: SCR catalyst with AdBlue, NOx storage catalyst and particulate filter according to ADAC. Seven-speed Steptronic dual-clutch gearbox, front-wheel drive. BMW quotes 7.9 s for 0–100 km/h and 222 km/h; WLTP combined consumption 4.8–4.3 l/100 km (125–112 g/km CO2), Euro 6e. Timing chain according to ADAC.
Oil change: 6.5 l according to BMW’s 06/2024 specification sheet (“oil change amount”). For top-ups the handbook lists BMW Longlife-12 FE or Longlife-17 FE+, SAE 0W-20 or 0W-30 (if unavailable, up to 1 litre of ACEA C2 or C5), with no additives. The level is measured electronically: it is monitored while driving (a value is available after about 30 minutes of normal driving), and a detailed measurement is started with the car level, engine warm and selector in N or P, under Apps › Vehicle › Vehicle status › Engine oil level › Oil level measurement. The handbook advises running it after every refuelling. Only add oil when the car asks for it, by the quantity given in the message.
The electric motor integrated into the dual-clutch gearbox acts as a starter generator: 15 kW and 55 Nm, added to the combustion engine’s 110 kW and 360 Nm for a total of 120 kW and 400 Nm. It is fed by a 20 Ah 48-volt battery under the luggage floor (300-litre boot), recharged by energy recovery when braking and decelerating. The handbook says not to remove that floor, fold its front part up or work on the battery. To charge the 12-volt battery, with the engine off, use the jump-start points in the engine compartment with the bonnet open. There is no charging socket: this is not a plug-in hybrid.
F70 diesels inject AdBlue (ISO 22241-1) into the exhaust to cut nitrogen oxides; the filler is next to the fuel cap and the level is shown under Apps › Vehicle › Live Vehicle › Adaptive content › Vehicle status › AdBlue. Yellow warning: add at least 5 litres; tank empty: at least 10 litres, or the car will not restart once switched off. BMW recommends having AdBlue topped up at the service; below −11 °C, only add it just before driving off. Diesel: EN 590 with 7% biodiesel (B7) recommended, B10 at most; paraffinic diesel to EN 15940 (XTL) allowed; never petrol.

The car calculates each due date from how it is used (Condition Based Service) and briefly shows the next date or remaining distance after switching on; details, including statutory inspections, are under Apps › Vehicle › Vehicle status › Service. BMW’s regular maintenance covers engine oil, brake fluid, a vehicle check, air filter, cabin microfilter and fuel filter. Some items depend on time, such as replacing fluids: have the workshop update them. Neither the handbook nor BMW’s list sets a mileage or period: the dates are the ones your car displays.
Check the first-registration date and the power on the registration document (BMW: 120 kW total, of which 110 kW from the diesel engine). Note the items and dates shown under Apps › Vehicle › Vehicle status › Service. Give the service advisor the key the car was last driven with: the car stores its service data in it. Ask for 6.5 l of a BMW-approved oil, then check that the work is entered in the electronic Service History, which replaces the printed service booklet and can be viewed by a later owner.
Due date calculated by CBS
Oil change at the date the car displays; do not run past it. Top-up: BMW Longlife-12 FE or Longlife-17 FE+, SAE 0W-20 or 0W-30. If unavailable, up to 1 litre of ACEA C2 or C5. No additives. Only add the quantity the car’s message asks for.
Source [5]As the service requirement dictates
BMW lists as regular maintenance: brake fluid, a vehicle check to BMW specifications, air filter, cabin microfilter and fuel filter. Each item is triggered by the service requirement the car calculates.
Source [2]Calendar-based (CBS)
Some maintenance items depend on time, for example replacing operating fluids. The F70 handbook states that periods with the battery disconnected are taken into account; have the workshop update these items. The handbook gives no period.
Source [5]No owner intervention
The 48-volt battery sits under the luggage compartment floor: do not remove the floor or fold its front part up, and do not replace or work on this battery. Charge the 12-volt battery only with the engine off, through the jump-start points in the engine compartment, with the bonnet open.
Source [5]At the reserve warning
AdBlue to ISO 22241-1, filler next to the fuel cap. Yellow warning: add at least 5 litres; tank empty: at least 10 litres, or the car will not restart once switched off. BMW recommends having it topped up during regular maintenance. Below −11 °C, only add it just before driving off.
Source [5]Regular check, engine cold
Level correct at the Max mark in the filler neck, engine cold and climate control off. BMW recommends coolant to BMW LC-18, mixed 50:50 with water; do not mix additives of different colours. Up to two expansion tanks depending on the drive variant.
Source [5]The same 110 kW B47C20B engine, to which the 120d adds the 48-volt electric motor: 120 kW and 400 Nm instead of 110 kW and 360 Nm, 7.9 s instead of 8.3 s for 0–100 km/h, and 4.8–4.3 l/100 km WLTP instead of 5.2–4.6. In return, the boot shrinks from 380 to 300 litres. Same oil quantity: 6.5 l.
According to the handbook, mild-hybrid versions may coast without using any fuel, in D, with neither brake nor accelerator pressed and outside SPORT mode. Adaptive recuperation varies deceleration using navigation data and sensors, for example when approaching a vehicle ahead.

Yes, if the pump states EN 15940: the handbook allows paraffinic diesel to that standard (XTL) and diesel with up to 10% biodiesel (B10); the recommended grade is B7 to EN 590.

Use the jump-start points in the engine compartment and a donor car with a 12-volt battery, fully insulated clamps and no body contact between the cars. For a diesel, let the donor engine run for about 10 minutes before starting; no starting spray. Do not touch any part of the 48-volt system.

Up to 2,000 km, do not exceed 3,500 rpm or 150 km/h, and avoid full load and kick-down; then increase gradually. New tyres need a gentle approach for 300 km, the brakes for about 500 km. The same rules apply after these parts are replaced.
