ok so i got vag com and it came up with p1857, load signal: error message from ECU. Could this be as easy as a mass air flow sensor? Has anyone had the same code come up in there car?

no it's your ecu. check the harness on it and check the fuses next to it

its a bogus code due to cold start up and will clear its self

but the car rides like shit when i take off fast, its a tiptronic, seems like no boost. I have had a boost leak test, the turbo takin out to see if a bad turbo, any suggestions or is there any way it could be the mass air flow sensor
