Mercedes Benz ML500, 2005 Model
ML500, 2005 Model, Jerks and displays check engine lights non stop.

My recently acquired ML500 SUV jerks at low speeds, displays check engine with about 7 querries and drips engine oil from a silvery object close to the oil filter at the top of the engine. I need help please. I flushed the nozzles, didn't help, fuel filter is ok but don't know about the fuel pump. Plugs are new, engine oil is less than two weeks. I need help urgently.

You must remove the oil cooler and replace the three gaskets 46mm socket needed to remove bolt in oil filter housing.

Only but gaskets at M/B dealer.

It appears from the codes you posted that the right catalytic converter is clogged or has broken apart.

To verify, purchase Exhaust Back Pressure Gauge, remove the right front O2 Sensor, and install the gauge in the O2 sensor port.

Start the engine and read gauge. Any reading over ZERO means that the front cat. is damaged and must be replaced.
