The BMW M62 engine was released to replace the M60 and was produced from 2001 to 2003. Introduced in 1999, the BMW X5 E53 quickly gained a reputation as a dynamic sports SUV and the power of the standard 4.4-liter M62B44 seemed insufficient. Therefore, it was decided to modernize it and the M62B46 engine appeared.
Other modifications of M62: M62B35, M62B44, M62B48.

Disadvantages of the M62B46 engine
When the engine is running unevenly, the cause is air leakage in the manifold, problems with the flow meter and the crankcase ventilation valve. The malfunction is caused by dirty throttle valves, faulty throttle position sensors.
If you notice a leak, you need to check the valve cover gasket, coolant bath, pump, outlet manifold gasket.
