just picked up a 2002 allroad tt. has a check engine light because of catless dp's were installed by previous owner tryn to save a buck.

so have any of you put aftermarket cats in the dps? and would a set of spun magnaflows be ok? i can tig weld some new cats in too these stainless pipes at work if it will work. i just want the light off. cars bone stock and will be a daily . so i dont care about hp boost or upgrades just this damn annoying yellow light lol. help me kill it. please

 

so non of you have had personal xp with spun cats? on bi turbo Dps?

my cars bi not me

 

best bet to kill it is to buy new cats directly from audi... or get the car chipped and have them write out the 02 code.
