Nox Sensor And Intake System issue HELP

[Aaron W]

Hi,

Recently purchased a a3 2.0 fsi 04 plate, really nice condition and runs really smoothly, i connected up my brother in laws diagnostics machine, because i had a light on which read
00810: Sensor 1/2 for brake pressure
00778: Steering Angle Sensor
01424: Lateral acceleration Sensor
Now my engine management light came on the other day while out , it was a
P1072: Nox Sensor heating control signal: electrical error in circuit and
P2279: Intake air system leak, does anybody know , what exactly i need to sort , cause im overwhelmed a really ****** off atm

Start with the easy one first, P2279. Check the intake for any cracks, loose pipes etc.

Google the fault codes or look o. The Ross-tech wiki for symptoms/remedial actions.

00778 - Steering Angle Sensor (G85)
00778 - Steering Angle Sensor (G85)
Possible Causes

• Steering Angle Sensor (G85) Basic Setting lost

Possible Solutions

• Perform Steering Angle Sensor (G85) Basic Setting
  • See Vehicle specific Diagnostic Procedures for Details

Special Notes

• This Fault Code may also be stored even though the Steering Angle Sensor (G85) is properly calibrated (Basic Setting), though it may not be finally initialized yet. Check the Measuring Value Blocks (MVB) in the Steering Aid Control Module (J500 / #44) for details. The Initialization will usually take place during a test drive.

00778 - Steering Angle Sensor (G85): Faulty
00778 - Steering Angle Sensor (G85): Defective
Possible Causes

• Steering Angle Sensor (G85) faulty

Possible Solutions

• Check Steering Angle Sensor (G85)

Special Notes

• With steering wheel level, wheels pointing straight ahead, make sure G85 is reporting 0 degrees +/- 5 degrees. If a reading of +360 or - 360 degrees is found. Remove steering wheel and turn clock spring 1 turn in direction needed to fix. See repair manual.

So will that mean i will need to replace the abs pump?? Also when can i find the code for the exact one i may need?

 

[Aaron W]

Or just a sensor? Im gonna clean the sensor up as it may be a build of dirt change the pads and disc’s and go from there
