Default failed emmisions 97 a6q. 2.8 v6
It says " Exhaust gas recirculation flow insufficient detected" I just bought the car and he said he hadn't changed the plugs in 100,00 miles? I don't know where to start. Definitely would like to avoid the checkbook.

Default C4 100/A6 forum. Sounds like an EGR problem, maybe you can clean the valve
My 2.8 12v was OBD-I. =)

Default Egr? I'll look into it. I only know the old audis right now.
The other forum is too slow... No help.

Default Probably plugged up EGR passages.
If they are plugged up the sytem does not get up to temp and throws that code.
