BMW N55 petrol engine (3.0 l turbo six)

This applies to every car fitted with the N55 engine.

What the N55 is

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.

Engine oil

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 drive

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.
