The M850i xDrive produces 390 kW (530 PS) with the 4395 cc N63B44D engine. This page covers 2018–2025. Bodies covered: Coupé, Convertible, Gran Coupé. Dates combine documented configurations; not every body and transmission combination was available throughout. M850i xDrive retains the 390 kW/530 hp N63B44D V8 and all-wheel drive. This M Performance model does not use the M8’s S63. The N63 engine section separates its requirements from the early V8s; the 2015 US care programme must not be applied to this M850i.
BMW’s published oil-change quantity is 10.5 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. 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, N63B44D code and 390 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 N63 engine.
N63 is a family of twin-turbo petrol V8 engines. Early versions and later VALVETRONIC revisions are not interchangeable for parts or service specifications. Identify the revision by VIN; output and model badge alone are insufficient. Oil-change quantity depends on installation and is listed on the vehicle page.

US handbooks illustrate the revision differences: 6 Series II/15 lists Longlife-01 or Longlife-01 FE and SAE 0W-30, 0W-40, 5W-30 or 5W-40; 8 Series VI/21 excludes Longlife-14 FE+, Longlife-17 FE+ and SAE 0W-20 for 50i, leaving Longlife-01 FE and SAE 0W-30 in the published lists. These US top-up specifications are not universal European approvals: check the VIN-specific handbook and engine label. Do not add oil additives.
Timing uses chains. The consulted BMW documents give no universal scheduled replacement interval. The 2015 US N63 bulletin discusses replacement following diagnosis and technical approval; it establishes neither a guaranteed lifetime nor the same fault on all later N63 engines.
In January 2015 BMW North America issued a Customer Care Package for selected early N63 engines, covering air-mass meters, high-pressure injectors, vacuum pump, low-pressure fuel sensor/line, turbo intake seals and crankcase ventilation lines. It explicitly was a care programme, not a regulatory recall. Its F12/F13 scope ends with July 2012 production. The bulletin does not establish eligibility for a European vehicle, an N63 TU or an M850i. Check repair history and vehicle-specific diagnosis.
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.
