Wiring Diagram Allroad 2004 2.7T Auto
Hi there,
Can anyone send me a wiring diagram for a 2004 Allroad 2.7T Automatic, I want o modify the o2 sensor wiring and the SAI pump wiring.
Alternatively, does anyone know if the SAI system check can be switched off with the VAG COM software?
Thanks for your help,
Thomas

Re: Wiring Diagram Allroad 2004 2.7T Auto
If you buy a Bentley manual, you will have access to all wiring diagrams. What are you considering modifying on those 2 circuits. You can trick the ECU into not seeing the rear )2 sensors, as long as you keep them installed and leave the heater in the circuit, you can add a resistor across the sensor portion, it will give a constant reading which is satisfactory. As for the SAI, in order to delete, I believe it will require deletion from the ECU check sum.
I would scan and send the diagrams to you, but I have the paper version, the diagrams do not exactly flow, nor are they contained as separate systems, more like mashed together and all over the place.
