F40 · 2019–2024
Built from 2019 to 2024, the 118d uses the 110 kW B47 four-cylinder diesel engine. Identify it by the kW figure on the registration document; an oil change takes 5.5 l, and the car itself calculates its service dates.
Figures apply to the cited configuration and market; equipment and transmissions may vary by production date.

1,995 cc four-cylinder diesel turbo, B47 family (ADAC engine code B47C20B): 110 kW (150 PS) and 350 Nm. Gearbox: six-speed manual or eight-speed Steptronic automatic. BMW quotes 8.5 s (8.4 s with the automatic) for 0–100 km/h and a top speed of 218 km/h. WLTP combined consumption on BMW’s 03/2021 sheet: 5.4–4.6 l/100 km (5.6–4.8 with the automatic). The four-cylinder diesel available with a manual gearbox. Its two-stage turbocharging combines a variable-geometry low-pressure turbo with a high-pressure stage integrated into the exhaust manifold; injection reaches 2,500 bar. Euro 6d-TEMP at launch, Euro 6d on BMW’s 11/2020 sheet.
Oil change: 5.5 l according to BMW’s 05/2019 specification sheet (“oil change”). The 11/2020 and 03/2021 sheets give the same quantity, as for the 120d. For top-ups, the handbook allows up to 1 litre of BMW Longlife-04 or Longlife-12 FE, SAE 0W-30, 5W-30, 0W-40 or 5W-40 (ACEA C2 or C3 if unavailable), with no additives. The level is measured electronically: it is monitored while driving, and a detailed measurement can be started with the car stationary, level and warm, under CAR › Vehicle status › Engine oil level. Only add oil when the car asks for it, by the quantity it displays.
The car calculates each due date from how it is used (Condition Based Service) and briefly shows the next date or remaining distance when switched on; details are under CAR › Vehicle status › Service required. BMW’s regular maintenance covers engine oil, brake fluid, a vehicle check, the air filter, the cabin microfilter and the fuel filter. Brake fluid is counted in time and periods with the battery disconnected are not counted: have the workshop update the time-based items. AdBlue comes on top: at least 5 litres at the yellow warning, 10 litres if the tank is empty (ISO 22241-1 fluid). Neither the handbook nor BMW’s list sets a mileage or period for these items: the dates are the ones your car displays.
The BMW documents consulted do not describe this engine’s timing drive. It appears neither in the handbook nor in BMW’s regular maintenance list: no replacement is scheduled. An unusual noise at start-up or idle still calls for a diagnosis.
Check the power on the registration document (110 kW) and the first-registration date. Note the items and dates shown under “Service required”. Give the service advisor the key the car was last driven with: the car stores its service data in it. Ask for 5.5 l of a BMW-approved oil, then check that the work is entered in the electronic service history, which a later owner can view. Also check the AdBlue level (CAR › Vehicle status › AdBlue): BMW expects one top-up between services as a rule.

Due date calculated by CBS
Oil change at the date the car displays; do not run past it. Top-up: up to 1 litre of BMW Longlife-04 or Longlife-12 FE oil, SAE 0W-30, 5W-30, 0W-40 or 5W-40 (ACEA C2 or C3 if unavailable). No additives.
Source [7]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 [8]Calendar-based (CBS)
Counted in time, not kilometres. Periods with the battery disconnected are not counted: have the workshop update the time-based items (brake fluid, and where applicable oil and microfilter). The handbook does not state the period.
Source [7]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. BMW expects one top-up between services as a rule, done by the workshop.
Source [7]Regular check, engine cold
Level between the Min and Max marks in the filler neck, engine cold. 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 engine.
Source [7]Same 1,995 cc B47 and the same ADAC engine code (B47C20B), but 110 kW and 350 Nm instead of 140 kW and 400 Nm. The 118d is available with a manual gearbox and only with front-wheel drive; the 120d is automatic only, also with xDrive. Both take 5.5 l of oil.
No: the BMW documents consulted for the F40 describe no 48-volt system. BMW introduced 48-volt mild-hybrid technology in the 1 Series with the fourth generation, presented in 2024.
EN 590 diesel with up to 7 % biodiesel (B7) according to BMW’s handbook; at minimum B10 or paraffinic diesel to EN 15940 (XTL). Never pure methyl ester or petrol: after a misfuelling, do not start the engine.

At the yellow warning, at least 5 litres; if the tank has run empty, at least 10 litres, or the car cannot be restarted once switched off. Use ISO 22241-1 fluid; the filler is next to the fuel filler, and the exact quantity is shown under CAR › Vehicle status › AdBlue.
