Hi everyone, I'm new in here. My Disco 4 61 plate went bang last week. Very loud knocking noise from the engine. The 4x4 garage the car was recovered to drained the oil and there was just 800ml of oil in the engine. I've had no warning lights suggesting low oil... Has this happened to anyone on here before? Currently looking at a new engine out of warrenty. Something I cannot afford at the moment...£8-12k. I've spoken to Land Rover HQ and they want the vehicle inspected for a possible fault on the oil level warning system. Help...please!
