1,998 cc four-cylinder petrol turbo (ADAC engine code B48A20E): 225 kW (306 PS) between 5,000 and 6,250 rpm and 450 Nm up to 4,500 rpm (from 1,750 rpm on the 10/2019 sheet, 1,800 rpm on the 03/2021 sheet). Eight-speed Steptronic Sport, xDrive and a mechanical Torsen limited-slip differential integrated into the gearbox; four-piston fixed callipers at the front. 4.9 s for 0–100 km/h (4.8 s with the M Performance package, according to the press kit), 250 km/h. WLTP combined: 7.8–7.1 l/100 km (BMW 03/2021). Uprated cooling: separate transmission oil cooler, 850 W electric fan, two remote radiators in the wheel arches and an enlarged expansion tank. 50-litre tank. EU6d-TEMP at launch, then Euro 6d, and Euro 6e from 03/2024 according to ADAC.
Oil change: 5.25 l according to BMW’s 10/2019 specification sheet (oil-change quantity). The 03/2021 sheet gives the same quantity. For top-ups, the F44 handbook (X/21) allows up to 1 litre of BMW Longlife-12 FE or Longlife-17 FE+, SAE 0W-20 or 0W-30 (ACEA C2 or C5 if unavailable), with no additives. The level is measured electronically: it is monitored while driving, and a detailed measurement can be started with the car stationary, level and warm, under CAR › Vehicle status › Engine oil level. Only add oil when the car asks for it, by the quantity it displays.
The car calculates each due date from how it is used (Condition Based Service) and briefly shows the next date or remaining distance when switched on; details are under CAR › Vehicle status › Service required. BMW’s regular maintenance covers engine oil, brake fluid, a vehicle check, the air filter, the cabin microfilter and the spark plugs. Brake fluid is counted in time and periods with the battery disconnected are not counted: have the workshop update the time-based items. Neither the handbook nor BMW’s list sets a mileage or period for these items: the dates are the ones your car displays.
Timing chain, according to the ADAC catalogue (“Steuerkette”). It is not among the regular maintenance items BMW lists: no scheduled replacement. An unusual noise at start-up or idle still calls for a diagnosis.
The ADAC catalogue lists no recall for this version (3 catalogue pages checked on 8 October 2026). That is not a guarantee: a BMW workshop can check the VIN for any open campaign on your car.
Check the power on the registration document (225 kW) and the first-registration date. Note the items and dates shown under “Service required”. Give the service advisor the key the car was last driven with: the car stores its service data in it. Ask for 5.25 l of a BMW-approved oil, then check that the work is entered in the electronic service history, which a later owner can view.

Due date calculated by CBS
Oil change at the date the car displays; do not run past it. Top-up: up to 1 litre of BMW Longlife-12 FE or Longlife-17 FE+ oil, SAE 0W-20 or 0W-30 (ACEA C2 or C5 if unavailable). No additives.
Source [5]As the service requirement dictates
BMW lists as regular maintenance: brake fluid, a vehicle check to BMW specifications, air filter, cabin microfilter and spark plugs. Each item is triggered by the service requirement the car calculates.
Source [1]Calendar-based (CBS)
Counted in time, not kilometres. Periods with the battery disconnected are not counted: have the workshop update the time-based items (brake fluid, and where applicable oil and microfilter). The handbook does not state the period.
Source [5]Regular check, engine cold
Level between the Min and Max marks in the filler neck, engine cold. BMW recommends coolant to BMW LC-18, mixed 50:50 with water; do not mix additives of different colours. Up to two expansion tanks depending on the engine.
Source [5]Yes: BMW’s press kit says this four-cylinder also powers the M135i xDrive and the X2 M35i, and ADAC gives the same code, B48A20E. The oil change is 5.25 l, as on the M135i xDrive.
The handbook specifies Super Plus RON 98 for the M Performance model. BMW’s sheets give a minimum of RON 95 (10/2019), then RON 91 (03/2021); the published performance assumes the recommended grade.
Yes: a standard mechanical Torsen limited-slip differential, integrated into the Steptronic Sport gearbox, which creates a locking effect between the front wheels. The BMW documents consulted give it no service interval.

On BMW’s sheets: EU6d-TEMP (10/2019), Euro 6d (03/2021). The ADAC catalogue lists versions sold from 03/2024 as Euro 6e. The exact class is on the registration document.
Electronically: the level is monitored while driving and shown under CAR › Vehicle status › Engine oil level after about 30 minutes of normal driving. For a detailed measurement, park on level ground with the engine warm and the gearbox in neutral or P, then start the measurement in the same menu.
