My A6 with 3.2 has the CEL and the "ESP off" indicator lights on. It is hard to start and runs a bit rough when cold. It smooths out somewhat when hot but is still not right. Fuel mileage has dropped from 22mpg to 19mpg. Car has 115,000 miles on it. Here are the fault codes and Freeze Frame. We can clear the codes but the P2294 comes back as soon as you start the engine and the other codes come back within a few minutes. The local shop is not sure if it's the High Pressure Pump/Regulator going bad or an electrical/wiring issue. He said there is power going to the regulator. This is not at a dealership. Thoughts??? Tests to try???

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
