Better Mileage Audi A6

[Huw Powell]

I would add to Mark's comment that if there is no MIL on, those sensors 
should all be good.

What kind of mileage did it used to get?

Obviously this is an illegal mod for a street car, but the chip tuners can accommodate.  Is the engine burning oil?  Vag-com can be used to watch the sensor inputs.  BTW, I'd put the coolant temp sensor and thermostat at the top of the list, as well as dirty or worn injector.  Techron is your easy friend there.

I want to change all 5 sensors and hope the mileage gets better. I also already changed the plugs and wires to help. I also was hoping to empty the cats for some better airflow.(I did this to my 1993 90cs v6 and it sounded great, but didn't pay attention to the mileage then). Does anyone have any thoughts or advice on this??
