2007 Audi A4 Quattro 2.0L oil consuption VIN: WAUDF78E47

2004 Volkswagen Touareg V8 4.2L Poor Idle Quality, Cuts out, Stall VIN: WVGCM77L94

2006 Volvo S60 2.5T 2.5L Surge, Cuts out, Stall, MIL Lamp on VIN: YV1RS59286
Basically ended up being fuel pump issue. You have to be very careful installing these pumps, it's very easy to mess up fuel lines and floats. One defective fuel pump in the mix added to the hair pulling. Trouble codes: P260D, P2600.
