Body identification

The launch N52 330i is a naturally aspirated six-cylinder with VALVETRONIC: 200 kW (272 hp), 2,996 cc and 315 Nm. This European page covers 2006–2007; markets retaining N52 later are not treated as following the European switch to N53.

Transmission and performance

Six-speed manual or six-speed Steptronic automatic. BMW quotes 0–100 km/h in 6.1 s for the rear-wheel-drive manual and 6.4 s for the automatic; these figures do not describe the 330xi. General N52 requirements are in the shared engine section.

Oil-change quantity

BMW specifies 6.5 l for both the 330i and 330xi Coupé. Check the final level: an oil-change quantity is not a top-up amount. Oil approvals and timing drive are documented in the shared N52 engine page.

Vehicle maintenance

The VIII/06 E92 handbook lists engine oil, front and rear pads, cabin filter, brake fluid, spark plugs and vehicle check separately in CBS. Service groupings changed later: use the handbook edition matching production. Bring the key last used to drive the car and check the vehicle date. No universal oil-change mileage is added here.

Recall checks

ADAC documents campaigns involving the Takata driver airbag, heater blower controller and battery connection. Affected periods and versions differ: check the VIN and completed repairs. A shared engine page does not replace this vehicle-specific check.

BMW N52 petrol engine (3.0 l naturally aspirated six)

This applies to every car fitted with the N52 engine.

What the N52 is

A naturally aspirated 2,996 cc inline six-cylinder petrol engine (88.0 × 85.0 mm) with a composite magnesium-aluminium crankcase and Valvetronic II. BMW launched it in 2005 in the E60/E61 5 Series and the E90 3 Series (330i, then the 325i with a lower-output version of the same 3.0), in two output stages: OL (upper, with the DISA resonance intake) and UL (lower, without DISA). BMW’s workshop documentation also lists an N52K, fitted for example to the 1 Series 125i and 130i.

Engine oil

Oil change with filter: 6.5 l for the N52 B30 and N52K B30 according to TIS data; 7.0 l on an N52K with the auxiliary engine oil cooler. BMW’s training material specifies SAE 5W-30. Longlife-04 is approved for petrol engines only in the EU, Switzerland, Norway and Liechtenstein; elsewhere, use the approval BMW specifies for the country.

Timing drive

Chain, at the front of the engine, on both the N52 and N52K: replacement goes through removing the cylinder head cover, the tensioner, the front radial seal and the vibration damper. No interval is set: it is a repair.

Magnesium block: workshop precautions

Ancillaries attached to the magnesium crankcase use aluminium bolts (blue heads): a steel bolt would cause contact corrosion. For the same reason, the gaskets between the aluminium cylinder head or oil pan and the magnesium block must not be damaged. Point this out to a workshop unfamiliar with the engine.

Maintenance and records

Engine oil change

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 [7]

Brake fluid

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 [7]

Vehicle check

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.
