Disadvantages of the M62B46 engine

The reason for the knock that appears may be an extended timing chain, which has a service life of up to 200 thousand km, as well as a tensioner bar, a chain bar, a tensioner. The resource of the Vanos system is similar to the resource of the chain, and it can fail. It is better not to delay checking and replacing.
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.
