BMW’s training material compares it with the naturally aspirated N52 six: 180 kW and 350 Nm as the N20B20O0, introduced for the 2012 model year (September 2011 in the US). It comes in several outputs, for example N20B20U0 in the 2014 2 Series.

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. The oil change quantity depends on the model: 5.75 l for the F30 320i (2012), 5.0 l for the F22 220i and 228i Coupé (2014) according to BMW’s data sheets. Have the figure confirmed for your car.

Timing drive

Chain drive in two parts: at the top, the camshaft timing chain, lubricated by an oil spray nozzle in the tensioner; at the bottom, a chain driving the oil pump and the balance shafts, with its own tensioner. No replacement interval is set.

Chain wear: US warranty extension

BMW of North America (bulletin SIB 11 03 17, September 2021 revision) acknowledges that a whine from the lower engine near the oil pump, rising with engine speed, can indicate excessive wear of the timing chain and/or oil pump drive chain on N20 and N26 engines. The prescribed fix replaces the oil pump chain module, timing chain, tensioner and rails. In the US, coverage of these parts is extended to 7 years or 70,000 miles for the listed models (production 2011 to February 2015); it is not a European recall. Elsewhere, such a whine deserves a prompt diagnosis.
