i also clean the maf, no effect at all

i can hear some air noise somewhere around the air intake but not sure if it's normal or not. is DISA valve make some light "swhhh" noise in normal running ? I didn't find leak or broken hose in this area.

i will investigate more on that ... if it could be only a broken air intake at 40$ i will be happy ... i need a break after the 2000$ in maintenance since i buy it 10 months ago (water pump, thermostat, tensionner, spark plug, cabin filter, o2 sensor, egr valve, reprogramming... yes, i got screw by a indy bmw mechanic... it was the only one around ... )
