Any help with a scanner code

thekeg · 06-12-2007, 11:19 PM

I have a code that returns a reading of "Catalyst system efficiency too low" on my 2002 TT Coupe. o2 Sensors? Gas? Cat converter? Any help would be great! I did reset the code and am waiting to see if comes on but should I have to replace O2 sensors at 61k miles?!

Sorry, but i dont have the answer your looking for. I'm assuming you have an OBD-2, are you using Vag-com? I just got Vag-com and really havent played around with it much. Whats your experiences?
I had a check engine light on.... code said "knock sensor #2"....... i erased the codes.... been 2 weeks and hasnt returned yet.
Maybe its how the service shops stay employed??
