av ordered a maf sensor from euro car parts,dam things expensive coz am not sure its that,i hav opened the ecu looked inside it the map sensor is only a little black box type thing soldered to the main ecu board.av tested the maf sensor,volt test should be 1.5volts on idle but shows me 1.55volts and sometimes 1.08volts put my vag tool onit checking meas blocks maf was out of range was reading to high on idle.hopeing its that.canit be the ecu or can u change the map seprate on them.if its not the maf.
