The 640i produces 235 kW (320 PS) with the 2979 cc N55B30A engine. This page covers 2011–2018. Bodies covered: Coupé, Convertible, Gran Coupé. Dates combine documented configurations; not every body and transmission combination was available throughout. N55 petrol six, 235 kW/320 hp: not the B58 used by the G32 640i Gran Turismo. Rear-wheel drive and xDrive share this variant where available.
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. Quantity from BMW’s launch Coupé tables; confirm the filter-inclusive quantity before filling a revised engine or another body.
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.

ADAC documents seat-mechanism and airbag campaigns on selected batches, plus diesel EGR-cooler campaigns. EGR applies to 640d, not petrol 640i/650i. Lists combine several bodies: check VIN and completed campaigns. The early N63 US care programme, explained in the engine section, is separate from a recall.

Bring the VIN, build month, N55B30A code and 235 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 N55 engine.
A 2,979 cc inline six-cylinder petrol engine (84.0 × 89.6 mm), successor to the N54. It replaces the N54’s two turbochargers with a single twin-scroll unit and is BMW’s first turbo engine with Valvetronic (Valvetronic III with double VANOS). Direct injection uses solenoid injectors instead of piezo ones. BMW’s training material introduces it in the F07 535i GT (N55B30M0, 225 kW, 400 Nm); it reached the 135i Coupé and Convertible in March 2010, and the 2014 2 Series data lists it as N55B30O0 in the M235i.
BMW’s owner’s manual for the F20 1 Series (X/14) allows BMW Longlife-01, Longlife-01 FE and Longlife-04 oils for petrol engines, in SAE 0W-40, 0W-30, 5W-40 or 5W-30. Longlife-04 is approved for petrol engines only in the EU, Switzerland, Norway and Liechtenstein. Oil change quantity: 6.5 l for the F22 M235i (2014) and the F30 335i Touring (2013) according to BMW’s data sheets; it may differ on other models. The level is measured electronically by the oil quality sensor.
Timing chain, mounted on the crankshaft with an M18 central bolt according to BMW’s training material; BMW’s parts catalogue lists it with guide rails and tensioner. None of the sources consulted gives a replacement interval: it is a repair, not a maintenance item.
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.
