Having problems with your 1999 Volvo S80 ?
My 1999 Volvo S 80 failed the NCT Test - emissions problem - even after new Lambda sensor was fitted - any suggestions
Scan the computer for any other trouble codes. Other sensors can throw off fuel/air mixture too. In future, posting what component(s) of your emission gasses failed would be useful. Be sure to test the car when it is good and warmed up and has been running for a while, don't let them test you cold!
