Upgrade oil pump for BMW N57

Check your vehicle registration document - field 5 (engine capacity) should show 2993 cm³. You can find the engine code stamped on the engine block next to the oil filter housing, or in the CoC certificate under field 0.2.

The engine stays in the car. But the front timing chain cover must be removed - this is several hours of workshop labor. On some N57 variants, the engine must also be separated from the transmission (the "closed" variant in the variant selection).

Because it is the only upgrade pump on the market that actively increases oil pressure at idle - to a stable 1.3-1.5 bar when the engine is at operating temperature. The integrated pressure relief valve regulates the maximum pressure to 5-6 bar, without an additional oil filter housing. It is based on the strongest standard Pierburg pump (N57D30C). Standard replacement pumps only replace the old pump with an identical new one - they do not prevent the pressure drop caused by wear.

It fits - we supply the correct variant via the variant selection above. If you're unsure, just call us on 0542 1614433.

On an N57 with low oil pressure at idle, lubrication of the connecting rod bearings and the timing chain becomes critical. The result can be bearing damage, timing chain damage, rattling noises and, in the worst case, catastrophic engine failure. Exactly when that will happen cannot be predicted - the recommendation is: act before symptoms appear, not after.

Yes, B2B terms are available from 5 units. Inquiries to b2b@mikmotoren.de.

The code is stamped on the engine block next to the oil filter housing (e.g. "N57D30C"). Alternatively, it can be found in the CoC certificate under field 0.2 or in the vehicle registration document.

If you already own our EasyCheck oil pressure measuring device or have ordered it as well, the pump replacement is available at a reduced variant price. In that case, select the appropriate "for Easy Check owners" variant.

On some N57 variants, the pump chain is accessible from the outside ("open / plug-in") - this makes the job easier. On others, the engine must be separated from the transmission to access the pump ("closed"). Which variant your vehicle has depends on the model and year of manufacture - if you're unsure, just call 0542 1614433.
