A3 2.0 16V 103kW (2010) - Noise when engine is cold
 

When engine is cold and realise throttle to slow down before a road bumps on low rpm (1500 and less) or when go uphill about 2000-3000 rpm (whether throttle on max or not, but when I swift up its stops until same range of rpm) could heard strange noise, as tapping, clanging..could it be camshaft, engine block/gearbox carrier or what?
NB When engine is hot there is no any strange sound..

How long have you been experiencing this noise? How many miles on the engine? Has the engine had the EPA fix?

I bought that car just few weeks ago. Its imported from Germany. Engine code is CFFB, 264000 km, removed PDF (hardware&software)..not by me
