B8 A4 Crank No Start CEL and EPC Light On - Need Advice

[felixclowers]

First I apologize if this post ends up in the wrong place. Im new to posting and will make sure to adhere to all rules and standards of conduct that are already set. Please chime in if anyone has ever experienced this problem.

I have a 2011 B8 A4. I come out to crank it, it starts but misfires and stumbles horribly. Turned the car off and waited a moment. Tried to start once more and now I have crank no start. Also the EPC and the CEL light are displayed.

After towing home I used a OBD 2 scanner to check for any codes and it pulled p2294 - http://wiki.ross-tech.com/wiki/index...6/P2294/008852

18726/P2294/008852 - Fuel Pressure Regulator Valve (N276): Open Circuit
Possible Symptoms

Malfunction Indicator Light (MIL) ON

Possible Causes

Wiring and/or connections faulty
Fuel Pressure Regulator Valve (N276) defective

Possible Solutions

Check wiring and connections
Check / Replace N276

Special Notes

On some engines, the N276 may be refered to as the N290 in the factory wiring diagram.


So far I have changed the Crankshaft Position Sensor and HPFP. After changing the HPFP I erased the code and scanned to see if the code would come back and it does not which leads me to believe the the HPFP was faulty and has been fixed. I have verified that fuel is pumping and I have spark. Also the battery is brand new. Has anyone else experienced this problem or can anyone give any ideas to a possible solution? All suggestions will be considered.

-Thanks

Is there anyone here that can chime in? I would really like to hear feedback and get my Audi back on the road. Also if there is anyone in the Atlanta area with a VAGCom that is willing to scan I will gladly pay for their time. Would like to avoid going back to the dealership for something that could be done myself.

Misfire might be from a bad fuel injector flooding the cylinder head. It will keep dumping fuel but the cars have a safety so nothing goes boom. lol I'd check the fuel injectors and valves.

Or the MAF even.

Thanks, I will be checking both.

update - I have a mechanic that will be checking the fuel injectors and valves. I pulled the MAF and tried to start to see if anything would happen and of course nothing happened. The exact same symptoms. Could the ECM possibly be a problem as well?

Did you ever figure out the issue on this? I am having the same issue and I pulled codes for VagCom and it seems it's fuel related. I can test further but would help if there was some direction back on this. Thanks!
