The 840d xDrive produces 250 kW (340 PS) with the 2993 cc B57D30B engine. This page covers 2020–2025. From November 2020, 840d xDrive uses the 250 kW/340 hp B57 with 48-volt assistance. It is a mild hybrid without a plug; do not add the starter-generator’s 8 kW to rated output. The Gran Coupé table gives a 7.0 l oil change, versus 6.5 l for the 320 hp version.

The 840d xDrive produces 250 kW (340 PS) with the 2993 cc B57D30B 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. From November 2020, 840d xDrive uses the 250 kW/340 hp B57 with 48-volt assistance. It is a mild hybrid without a plug; do not add the starter-generator’s 8 kW to rated output. The Gran Coupé table gives a 7.0 l oil change, versus 6.5 l for the 320 hp version.
BMW’s published oil-change quantity is 7.0 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. The quoted quantity comes from this engine version’s BMW Gran Coupé table; launch Coupé tables also confirm the initial 840d and M850i. Check the VIN-matching edition for other bodies and later revisions.
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, B57D30B code and 250 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 B57 engine.
Inline six-cylinder diesel engine of 2,993 cc with common-rail direct injection, from the same modular family as the B47 and B58. The number of turbochargers depends on the version. ADAC gives three codes: B57D30A for the 2017 G30 530d (195 kW/265 PS, 620 Nm, Euro 6c), B57D30C for the 2016 G11 750d xDrive (four turbochargers, 294 kW/400 PS, 760 Nm) and B57D30B for the 2020 facelifted 530d (48 V mild hybrid, twin turbo, 210 kW/286 PS, 650 Nm, Euro 6d-ISC-FCM). All have SCR, a NOx storage catalyst and a particulate filter.
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 or -12 FE — the handbook adds that Longlife-12 FE is not suitable for the 25d, 35d, 40d and 50d diesels — in SAE 0W-30, 5W-30, 0W-40 or 5W-40 (0W-20 and 5W-20 are excluded for diesels); otherwise up to 1 litre of ACEA C2 or C3. No additives. The Longlife-12 FE restriction names the “50d” designation, that of the four-turbo 750d (B57D30C); for a 30d the handbook allows it. No B57-specific oil-change quantity was found in the BMW sources consulted: ask the workshop for the figure for your VIN.

Chain, according to ADAC. BMW’s training documents on the modular family explain that, because the crankcase is shared by petrol and diesel engines, the timing drive is two-part: a lower chain drives an intermediate shaft, which on the diesels also drives the high-pressure pump, and an upper chain drives the camshafts. The sources consulted give no replacement interval.
In October 2018 BMW expanded a technical campaign on the EGR module of certain diesels: glycol leaking from the EGR cooler, combined with soot deposits, can create smouldering particles and, very rarely, melt the intake manifold or cause a fire. About 1.6 million vehicles worldwide, built August 2010 to August 2017, with periods varying by model; the module is checked and faulty parts replaced. BMW does not list engine codes, so have the VIN checked.

2016: four-turbo 750d xDrive, presented by BMW as the world’s most powerful six-cylinder diesel — injection above 2,500 bar, peak combustion pressure raised from 200 to 210 bar, head and crankcase castings densified by hot isostatic pressing, twin-wire arc-sprayed cylinder bores. 2017: G30 530d (B57D30A, Euro 6c). 2020: facelifted 530d as a 48 V mild hybrid (B57D30B), 210 kW and 650 Nm, Euro 6d-ISC-FCM.
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.
