The 640i produces 245 kW (333 PS) with the 2998 cc B58B30C engine. This page covers 2020–2023. Bodies covered: Gran Turismo. Dates combine documented configurations; not every body and transmission combination was available throughout. This facelift 640i uses the 245 kW B58B30C with 48-volt assistance and no external charging. The 8 kW starter-generator is not arithmetically added to the rated output. Identify the 48-volt equipment when preparing service; oil quantities are from BMW’s 2020 table.
BMW’s published oil-change quantity is 6.5 l. This is a service quantity, not an amount to pour in as a top-up: check the level after filling. Oil approvals, timing drive and shared engine characteristics are detailed in the engine section.
BMW’s 2018 maintenance booklet explains CBS items: oil and vehicle check use time and distance, brake fluid uses time and brakes depend on wear. Cabin and air filters, spark plugs or diesel fuel filter are combined with selected oil-service counters and may not appear separately on screen. Replace oil and oil filter together; obtain the associated work list using VIN, service history and CBS counter. The accessible booklet is American: its numerical intervals are not transferred to European diesels or the 48-volt facelift.

The consulted ADAC recall list includes facelift G32 in a starter fire-risk campaign. This does not mean every engine or every G32 is affected. Check VIN, production period and campaign completion; do not extend that scope to pre-facelift cars.

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 [6]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 [6]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.
