Noise variator and engine tapping noise at cold start. Oil that stick on variator or oil that get quick to the engine part is what engine and variator need. Engine over 70000 Km? Remember engine tollerance change "dirty, wear, oil consumption and etc..." so the oil pressure change! also remember that the oil filter has a valve that should be open at pressure of......PSI so if there is a pressure delay at start or at "cold start" than there is a problem, so at some point you need compensate all this! an excellent solution "on my 156 ts" was Selenia HPX 20W/50, cost a bit does the job last over 15000 Km (A3), and and raise oil pressure, again raise oil pressure. Clean air filter it's important as well.
