Re: A4, 3.0, 2004, Catalytic converter problems
I have a 2003 A4 3.0L with Cat issues as well. Code P0421, and Po431. Both to due with: Warm-Up Catalyst Below Threshold (Bank 1 & 2). From what I've heard this job is a PITA, and so it's not cheap.... Any experiences 3.0L owners out there that took care of this? how?

Hi,
An engine light (yellow) came off during the driving.
My mechanic suggested a few driving tips to try before we do change converters. So far so good.
Thanks
