I have just picked up my 2.0ti 146 and they told me that it failed because lambda reading was; 7.3.2b. and the same for carbon monoxide and hydrocarbon. The tester said he could try and fit a new cat but that might not cure it!. They are talking telephone numbers for the work etc and I feel as if I should scrap the car which upsets me!. Any ideas? as the car is a perfect runner.
