hello all!
Jim hailing from the Charlotte NC Area. been in Audi's for several years with 0 issues.
Recently purchased a used '13 Q5 PP to haul my dogs around in. Ran fine first few months. then developed a pretty severe stutter/hesitation at 1900-2200 RPM with a load on the engine. if no load there's was very little of it. no codes first few months. finally threw a misfire on one cylinder. I changed all plugs and coil packs and it reduced hesitation/stutter by like 80%. changed out the fuel pump/filter assembly about a month ago with an Audi unit from ECSTuning and it reduced it a further 10-15%. 2 days ago, driving to town and after 5 minutes of driving she stuttered REAL BAD and shut off. current bad codes from VCDS are as follows:
P2294 Fuel Pressure Regulator Valve (N276) Open Circuit
P261A Coolant Pump 2 Open Circuit (coolant temp at time of failure was only 98C)
P310B Low Pressure Fuel Regulation - Fuel Pressure Outside Spec - MIL on - Confirmed- Tested since memory clear
P2539 Fuel Pressure Sensor (G410) Open Circuit Intermittent - Not Confirmed - Tested Since Memory Clear
P0087 FuelRail/System Pressure - Too Low Intermittent - Not Confirmed - Tested Since Memory Clear
Right now its hit or miss, sometimes she will start right up and run for 3-8 minutes, sometimes she just urns over and never fires...
Im thinking its going to be a loose wire somewhere...Also, I'm still able to get like 500+ miles per tank so I never saw any reduction in fuel economy
Thanks ahead of time for any expert opinions I may find here!!
