Just a quick question, since our ozzie techs have NFI on the astra cars i thought i might come to you guys and get some answers.
The car is throwing up an emissions error.
I have had the o2 sensor changed under warranty but still the same problem.
The Tech 2 reads it as a cat error. I have had my cat looked at at an exhaust place and it seems fine.
The error disappeared for a few weeks all on its own but has suddenly returned once again out of the blue.
