1,998 cc four-cylinder petrol turbo (ADAC engine code B48B20A): 135 kW (184 hp) between 5,000 and 6,500 rpm and 300 Nm between 1,350 and 4,000 rpm. BMW highlights the exhaust manifold integrated into the cylinder head, which made its debut in this engine, twin-scroll turbocharging, direct injection at up to 350 bar and split cooling for the crankcase. Eight-speed Steptronic automatic, rear-wheel drive; Steptronic Sport standard since the 2024 update. BMW quotes 7.5 s for 0–100 km/h and 236 km/h; WLTP combined 6.8–6.3 l/100 km (155–144 g/km) at launch under Euro 6d, then 6.9–6.4 l/100 km (158–145 g/km) under Euro 6e on the 06/2024 sheet. Timing chain according to ADAC.
Oil change: 5.25 l according to BMW’s 07/2021 and 06/2024 specification sheets. For top-ups, the G42 handbook (VI/22) lists BMW Longlife-12 FE or Longlife-17 FE+, SAE 0W-20 or 0W-30 (if unavailable, up to 1 litre of ACEA C2 or C5), with no additives. The level is measured electronically: it is monitored while driving (a value is available after about 30 minutes of normal driving), and a detailed measurement is started with the car level, engine warm and selector in N or P, under MENU › Vehicle apps › Vehicle status › Engine oil level › Oil level measurement › Start measurement. The handbook advises running it after every refuelling. Only add oil when the car asks for it, in the quantity given in the message.
The car calculates each due date from how it is used (Condition Based Service) and briefly shows the next date or remaining distance after switching on; details, including statutory inspections, are under MENU › Vehicle apps › Vehicle status › Service requirements, and completed work under Service History. BMW’s regular maintenance covers engine oil, brake fluid, a vehicle check, air filter, cabin microfilter and spark plugs. Brake fluid and, where applicable, oil and microfilter also depend on time; periods with the battery disconnected are not counted, so have the workshop update them. Neither the handbook nor BMW’s list sets a mileage or period.
Check the first-registration date and the power on the registration document (135 kW). Note the items and dates shown under MENU › Vehicle apps › Vehicle status › Service requirements. 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. Have the VIN checked against the starter recalls listed by ADAC, then check that the work is entered in the electronic Service History, which a later owner can also 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: BMW Longlife-12 FE or Longlife-17 FE+, SAE 0W-20 or 0W-30, for petrol and diesel alike. If unavailable, up to 1 litre of ACEA C2 or C5. No additives. Only add the quantity the car’s message asks for.
Source [8]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.

Brake fluid and, where applicable, engine oil and the microfilter/activated-carbon filter also depend on time. The G42 handbook states that periods with the battery disconnected are not taken into account: have the workshop update these items. The handbook gives no period.
Source [8]Regular check, engine cold
Level correct just below the Max mark in the expansion tank filler neck, engine cold. BMW recommends coolant to BMW LC-18, mixed 50:50 with water; do not mix additives of different colours. At delivery the tank may be overfilled: the normal level settles with use.
Source [8]The same 1,998 cc block (B48B20A for both according to ADAC), tuned for 135 kW and 300 Nm instead of 115 kW and 250 Nm: 7.5 s instead of 8.7 s for 0–100 km/h. The handbook allows a 1,600 kg braked trailer instead of 1,300 kg. Since 2024 the Steptronic Sport transmission is standard on the 220i and optional on the 218i. The oil quantity is the same: 5.25 l.
No: same 135 kW and 300 Nm, same 5.25 l of oil. The 06/2024 sheet gives slightly higher WLTP figures (6.9–6.4 instead of 6.8–6.3 l/100 km) and Euro 6e. ADAC keeps the B48B20A for versions sold from August 2025.
The handbook recommends a detailed measurement after every refuelling, and regularly with frequent short trips or sporty driving, when monitoring may not produce a value. Consumption can rise with sporty driving, during running-in, when idling or with unsuitable oil. Too little oil damages the engine; too much can damage the engine or the catalytic converter.

The handbook specifies Super RON 95, with unleaded RON 91 as the minimum. Ethanol is allowed up to 25% (E10, E25). On RON 91 or with more than 10% ethanol, knocking and noticeable changes in driving behaviour and noise are possible, with no effect on engine life according to BMW. Published output and consumption refer to RON 98 E10. Never use leaded petrol or metallic additives (manganese, iron).

ADAC lists three BMW starter recalls for this generation, all for fire risk and all fixed by replacing the starter: October 2025 for cars built up to 09/2021 (relay insufficiently protected against water), February 2026 for 05/2020–10/2024 and July 2026 for 07/2020–02/2026 (wear deposits in the relay). Not every car is affected: have your VIN checked.
