Original Quality Oil Pan Lower Section 11138580122 for BMW B48 B58 G20 G22 G23
This lower oil pan, reference number 11138580122, is a direct fit replacement component manufactured to original equipment specifications for BMW models equipped with B48 and B58 engines. As the lowest point of the engine lubrication system, it stores the engine oil, houses the oil level sensor and oil temperature sensor, and incorporates a built in baffle to prevent oil starvation during cornering and hard acceleration. Constructed from high pressure die cast aluminium alloy, this oil pan offers excellent structural rigidity, thermal conductivity, and impact resistance against road debris. The precision machined sealing flange and bolt holes match the original dimensions exactly, ensuring a leak proof fit when installed with the recommended sealant and new fasteners. This lower section is compatible with BMW G20 3 Series, G22 4 Series Coupe, and G23 4 Series Convertible models from 2019 onwards, covering 320i, 330i, 340i, 430i, and M440i variants. Common failure symptoms include oil seepage from the pan gasket, visible cracks or impact damage, and low oil pressure warnings caused by reduced oil capacity due to leaks; replacing with our unit restores proper oil retention and protects the engine from catastrophic failure. Every component undergoes 100 percent porosity testing, dimensional verification, and pressure integrity checks prior to dispatch. The material meets OEM corrosion resistance and fatigue strength standards, ensuring long term durability under harsh thermal cycling and vibration conditions. Backed by a 24 month warranty against manufacturing defects, this lower oil pan offers workshops and individual owners a durable, cost effective solution that maintains your BMW’s lubrication performance and extends engine service life. Installation is straightforward with standard tools and is ideal for routine oil pan gasket replacement or collision repair.
