Check injector values with VCDS.
Pull the valve cover and check camshaft and lifters.

Use a stethoscope or hose-in-ear to isolate the sound. Valve cover or Injection Pump most likely culprits.

Just throw some new pistons, rings, connecting rods and bearings, crankshaft and main bearings, cranks seals, oil pump, a rebuilt head, injection pump, and some new injectors in it and the sound should go away.
