My 2002 a4 3.0 quattro stalled the other day and then started to bog down in low rpms. It occasionally stalls out when it gets under 1k rpms. The ESP turned off and i culdnt turn it back on and the check engine light cam on. I got the readings P0101, P0300, P0172, and P0175. I know the problem can consist of a few things with the MASS air flow censors or the fuel delivery. HAs any one else had a problem like this or maybe know of any commons problems. Any suggestions can help i do not really wanna go spend thousands at the dealership.

Thanks

From the fault codes it looks like you need a MAF. The MAF sensor is also tied into the ESP system so a faulty maf can cause that too.
