G26 · 2021–2025
The M440i xDrive Gran Coupé uses the 275 kW (374 hp) six-cylinder with 48-volt mild hybrid; a rear-wheel-drive M440i joined it in summer 2022. To check this is your version, compare with the 275 kW on the registration document. An oil change takes 7.2 l.
Figures apply to the cited configuration and market; equipment and transmissions may vary by production date.

2,998 cc six-cylinder (ADAC: B58B30B): 275 kW (374 hp) between 5,500 and 6,500 rpm, 500 Nm between 1,900 and 5,000 rpm, 8 kW of electric boost. M440i xDrive: 0–100 km/h in 4.7 s; rear-wheel-drive M440i (from July 2022): 5.0 s, with Steptronic Sport transmission and M Sport differential. 250 km/h. ADAC lists both until 06/2024, then the M440i xDrive from 07/2024 to 09/2025.
Oil change: 7.2 l according to BMW’s specification sheets (06/2021, 05/2022, 07/2024). Approvals and viscosity grades: see the “B58 engine” block on this page.
Due dates are calculated by Condition Based Service from how the car is used. BMW’s regular maintenance covers engine oil, brake fluid, a vehicle check, air filter, cabin microfilter and spark plugs, each triggered by the calculated service requirement. BMW’s list sets no mileage or period: the reference is the date your car displays.

Check the power on the registration document (275 kW) and note the items and dates the car displays. Ask for 7.2 l of a BMW-approved oil. Have the VIN checked against the recalls listed by ADAC and keep a record of every job.
This applies to every car fitted with the B58 engine.
Inline six-cylinder petrol engine of 2,998 cc (82 mm bore, 94.6 mm stroke, 11:1 compression) with twin-scroll turbocharger, direct injection, double VANOS, a closed-deck crankcase and indirect charge-air cooling integrated into the intake. BMW places it in the same modular family as the B38, B48 and B57, and launched it in mid-July 2015 in the F30 340i (240 kW/326 PS and 450 Nm according to ADAC, which codes it B58B30A). BMW designates the version in the facelifted 2 Series M240i (2017) as B58B30M0. In 2021 the G42 M240i xDrive Coupé quotes 275 kW (374 hp) and 500 Nm from the same displacement.
BMW handbooks only list oils for topping up and leave the oil change to a qualified workshop; the list depends on the handbook edition. 5 Series G30 handbook (VI/20): BMW Longlife-04, -12 FE or -17 FE+, in SAE 0W-20, 5W-20, 0W-30, 5W-30, 0W-40 or 5W-40; otherwise up to 1 litre of ACEA C2 or C3. 2 Series Coupé G42 handbook (VI/22): BMW Longlife-12 FE or -17 FE+, in SAE 0W-20 or 0W-30 only; otherwise up to 1 litre of ACEA C2 or C5. No additives. Quantities published by BMW: 6.5 l for the B58B30M0 of the M240i (2017, “filling quantity”) and 7.2 l for an oil change on the G42 M240i xDrive Coupé (2021). No quantity is sourced here for other installations.
Chain, on the transmission side, confirmed by ADAC. According to BMW’s training document it is two-part: a lower chain drives an intermediate shaft, which passes the drive to the upper camshaft chain; the oil pump has its own chain and the tensioners are hydraulic with spring preload. The inertia of the transmission reduces the torsional vibrations acting on the chain. The sources consulted give no replacement interval.
2015: launch in the F30 340i, replacing the N55 (2,979 cc, 225 kW); Euro 6b according to ADAC. 2017: facelifted 2 Series, M240i with B58B30M0. 2021: G42 M240i xDrive Coupé, 275 kW (374 hp) and 500 Nm, Euro 6d. The sources consulted do not detail the internal changes between these versions, so nothing more should be inferred.
As the service requirement dictates
BMW lists as regular maintenance: brake fluid, a vehicle check to BMW specifications, air filter, cabin microfilter and spark plugs. Each item is triggered by the service requirement the car calculates.
Source [1]Same engine and the same 7.2 l oil change; the rear-wheel-drive M440i needs 5.0 s from 0 to 100 km/h against 4.7 s for the xDrive, and gets the Steptronic Sport transmission and the M Sport differential. ADAC lists the rear-wheel-drive version from 07/2022 to 06/2024.
275 kW on the registration document here, 288 kW for the M440i xDrive Gran Coupé announced in autumn 2025. ADAC ends this version in 09/2025.
For M Performance models such as this one, the handbook asks for Super Plus RON 98 to reach the published figures; the minimum remains unleaded RON 91, and ethanol is allowed up to 25% (E10, E25). Never use leaded petrol or metallic additives. (These rules come from the Coupé handbook, which shares the same engines.)
ADAC lists three BMW starter recalls covering this generation of the 4 Series: October 2025 (built 09/2015–09/2021), February 2026 (05/2020–10/2024) and July 2026 (07/2020–02/2026). A relay poorly protected against water, or wear deposits in it, can cause a short circuit and a fire; the starter is replaced. Not every car is affected: have your VIN checked.

Up to 2,000 km, do not exceed 4,500 rpm or 160 km/h, avoid full load and kick-down and do not use Launch Control; then increase gradually. New tyres need a gentle approach for the first 300 km, the brakes for about 500 km. The same rules apply after these parts are replaced.
