The knocking, tick-tick-tick noise seems to be common, it is from DI.

Is the AC evaporator running? Note that AC can be on even if the AC light is not lit. Can the "vibration" noise due to AC running?
What does DI stand for? If you mean diesel, the engine is N55 which runs on petrol not diesel. The noise is normal in diesel engines like N47, B47 and N57.
