2011 A4 shutting off while driving...

[twcman306]

Hello, my A4 is APR stage 1 and Ive been having some trouble with it during my commutes to work. During the little hiccups, the motor would not rev past 2500 and then would shut off followed by a whole host of error messages. I scanned it tonight and Code: P2294
Category: Powertrain
Definition: Fuel Pressure Regulator 2 Control Circuit/Open

This is what came up. Any info on this problem would be greatly appreciated. Thanks!

overheating perhaps? maybe a fan or pump is not working

[simplicity]

I take no credit for this but searched your code and this is what came up:

P2293 & P2294

Possible Causes:

Fuel Pressure too Low
Intake Camshaft Failure

Possible Solutions

Check Measuring Values for Fuel Pressure
Check for bent/squeezed Fuel Lines
Check Fuel Pressure System for Leaks
Check Fuel Filter & Filter in Fuel Pump
Check Fuel Quantity supplied by the Fuel Pump


Special Notes

Check Fuel Pressure

North American Region (NAR) check TSB 2015153 (01-09-03 > 15-10-01 > 15-10-02), the Intake Camshaft might have a worn out Fuel Pump Cam.

Check the Fuel Pressure first.

Special Functions

Checking Fuel Pressure

Prerequisites:

Ignition ON
Engine ON (Idle)
System voltage at least 11.0 V.
Coolant Temperature at least 80 °C

[Select]
[01 - Engine]
[Meas. Blocks - 08]
Group 103
[Go!]
Field 1: Fuel Pressure (Low), Specification: 2800...7200 mbar
Field 2: Fuel Pump Adaptation, Specification: -1000...+1000 %

Group 140
[Go!]
Field 3: Fuel Rail Pressure (High), Specification: 25.0...110.0 bar
Increase the Engine Speed while checking this value, the Pressure has to rise with the Engine Speed.

Group 230
[Go!]
Field 1: Specified Fuel Rail Pressure (High)
Field 2: Actual Fuel Rail Pressure (High), Specification: 25.0...110.0 bar
Field 3: Deviation between specified and actual fuel pressure, Specification: max. 5.0 bar

[Done, Go Back]
[Close Controller, Go Back - 06]
North American Region (NAR) check TSB 2018183 (20-08-01) and verify the High Fuel Pressure Sensor (G247) Part Number


I would make sure you are giving the car high quality fuel either 91 or 93 octane - preferably top tier fuel as recommended by Audi and maybe throw in some fuel system cleaner from Chevron Complete Fuel System Cleaner. Perhaps you just got a bad batch of fuel...try a different station or something and see how it is....if the problem persists then I would look into fuel filter/pump. Good luck.

We talked about this issue in another thread. This happened to me once too with me chalking up to having the wrong dipstick. Someone mentioned it may have been the transmission filter.

High pressure fuel pump possibly as mine did the same thing, though it wasnt intermittent so maybe not

If so it was about 400 bucks out of warranty at dealer
