The 840i produces 245 kW (333 PS) with the 2998 cc B58B30C engine. This page covers 2020–2025. Bodies covered: Coupé, Convertible, Gran Coupé. Dates combine documented configurations; not every body and transmission combination was available throughout. European 245 kW/333 hp B58 840i, rear-wheel drive or xDrive. This revision predates the 2022 facelift and is not described by BMW as the 48-volt mild-hybrid diesel. The 840i badge alone therefore does not identify the output or technical-data edition.
The oil-change quantity for this version was not established in the consulted documents. It is not borrowed from another model with the same engine. Confirm the VIN-specific quantity including filter, then check the level as the handbook instructs. Oil approvals, timing drive and shared engine characteristics are detailed in the engine section.
CBS calculates service needs from use. Read engine oil, brake fluid and vehicle check separately in service requirements. Plan the oil filter with the oil change; have the cabin filter, air filter and spark plugs or diesel fuel filter itemised against the service counter. The consulted handbook does not give their complete version-specific schedule. Report storage with the battery disconnected so time-based items can be corrected.

The consulted ADAC pages list no detailed campaign for these 8 Series examples. This does not prove that recalls do not exist: request a VIN check of open campaigns with the original market and repair history. The early N63 care programme in the engine section does not automatically cover M850i.
Bring the VIN, build month, B58B30C code and 245 kW rating. Record CBS dates and counters, previous oil services and filter changes; bring the key used for the last journey. Have the oil and work itemised on the invoice and the service recorded. Report storage with the battery disconnected so time-based deadlines can be corrected.

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.
Oil deadline displayed by CBS
Record remaining date and distance before work. Use the version-specific quantity and a VIN-approved oil; check the level and record the oil service once completed. The consulted document does not justify a universal fixed mileage.
Source [1]Brake-fluid service date
Read the brake-fluid deadline separately from pad wear. Compare it with the last replacement invoice; report storage with the battery disconnected before correcting service dates. Reset only completed work.
Source [1]Vehicle-check deadline, separate from oil service
Keep the CBS vehicle-check item separate from oil service. Provide service history and the key last used so the workshop can read actual requirements. An oil change alone does not prove the vehicle check was completed.
