Sorry, that question was a bit vague.
Having emissions trouble at mot on a TT vvti (this cat plus second cat fitted) with very high CO 8% Vs 0.3 limit. Guessing this is an O2 sensor from the search.
I have the part number (89465-19725) but can only find parts from japan. Is that the only option now?
Any other known issues that cause this id appreciate you letting me know. Many thanks
