Project Details

When a 2020 BMW 740i arrived at Euro Auto Tech & Smog with a coolant leak, our team quickly went to work to identify the root cause. Through a detailed diagnostic process, we traced the issue to a failing oil filter housing—an increasingly common problem on BMWs equipped with the B58 engine.

This engine uses a plastic oil filter housing paired with a metal oil cooler, a combination that often leads to cracks or gasket failures over time. When this happens, drivers may experience sudden coolant and oil leaks, risking severe engine damage if left unchecked.

Our skilled technicians efficiently replaced the faulty oil filter housing, restoring the BMW 740i’s reliability and protecting the engine from potential failure. We always recommend B58 BMW owners pay close attention to this component during regular maintenance, as early detection can prevent costly repairs down the road.
