BMW Oil Pump Failure: What You Need to Know
BMWs are celebrated for their engineering and performance—but even the most well-designed engines can experience critical issues. At CG Motorsports, your trusted BMW specialist in Richmond, one of the more serious problems we encounter is oil pump failure. If left unresolved, this issue can lead to catastrophic engine damage and major repair bills.
What Does the Oil Pump Do?
The oil pump is responsible for circulating oil throughout your BMW’s engine, ensuring proper lubrication of internal components like camshafts, crankshafts, pistons, and bearings.
When the oil pump begins to fail, oil pressure drops, and these components can quickly wear down or seize—leading to full engine failure.
BMW Engines and Models Commonly Affected by Oil Pump Issues
While any BMW can suffer from oiling problems, several engines have shown a higher-than-average risk due to design flaws or wear patterns. These include:
S65 (2008–2013 BMW M3 E90/E92)
Known for rod bearing wear and oil pump drive gear issues, especially under track use or extended service intervals.
S85 (2006–2010 BMW M5 and M6)
High-performance V10 engine with a complex oiling system, a history of oil pressure loss, and bearing failure.
N54 (2007–2010 BMW 335i, 135i, 535i)
Common issues include oil pump or oil filter housing gasket leaks, leading to low pressure and engine overheating.
N63 (2009–2014 BMW X5, X6, 750i)
Known for oil pump and timing chain issues. BMW issued technical service bulletins and even an extended customer care package due to reliability problems.
N20 (2012–2015 BMW 328i, X3, X1)
The 4-cylinder turbo engine with reported cases of timing chain and oiling system issues.
B58 (2016–present BMW 340i, 540i, Z4 M40i, Toyota Supra GR)
Generally more reliable, but early production years (2016–2018) have reported oil pump drive gear issues, especially under high-stress driving. Symptoms include sudden loss of oil pressure and power.
If you drive any of these models and haven’t had your oiling system checked recently, it may be time for a BMW oil pump inspection in Richmond.
