Vauxhall Zafira B - Failed mot emissions - NickG15
Hi,

We have an 08 plate Zafira that has failed its emissions test miserably. When put on a Vauxhall computer indicated the oxygen sensor or thermostat. We changed that and also have put a new cat on, it's coming up with nothing else faulty but still failing on the emissions, do you have any clue why or advise on what we could try next?

Thank you

If you can post up the miserable fail emission figures,then forum members may be able to offer some assistance.Throwing parts at this ad infinitum is not the way to a fix.
