My car failed today on an exhaust leak on a couple of the joints, not that bad. I was testing up to 5 years ago and likely would have passed and advised if it went through the emmissions, in my experiece this leak would pass the emissions test 9/10, but probably would failed the leak too if it didn't and was sure it was a contributing factor to the emissions fail, but as I didn't test it, it doesn't really matter if I would or wouldn't have failed the leak with or without a pass on the emissions as this is up to the tester, but this part isn't my issue, just relevent to the situation.
I asked what the emissions test result was on the phone, the receptionist went to ask the tester and came back with it can't be tested because the exhaust is leaking. Picked it up, spoke to the tester, told me there is no point testing the emissions as it would definitely fail. prceeded to patronise me telling me how it will suck in oxygen and fail on lambda, I asked how do you know if you didn't test it, then claimed as soon as he probe the exhaust the lambda went sky high and stopped the test. I didn't bother engaging any further.
Lambda isn't checked on idle only at 2500-3000rpm at that engine speed there is likely more than enough pressure to stop any or at least enough oxygen entering the exhaust through the leak which is barely leaking more than a drain hole in a silencer.
I would have liked to know the CO% and HC at fast idle so I can dertermine for myself why, if at all, the emissions test failed. Which it didn't because the tester didn't do it...
Back in my day when I were a lad just assuming it will fail is not a reason to abandon the emissions test before it is complete and even if it fails the Basic Emissions Test a CAT test would still need to be carried out with the extended warm up time and amended limits based on the make and model of the car before a fail can be recorded.
Neither of these failures have been recorded, just the exhaust leak.
"Lambda coefficient outside the default limits or the range specified by the manufacturer [8.2.1.2.(c)]"
"Emissions test unable to be completed [8.2.1.2. (d)]"
Can a tester now choose not to carry out the emissions test because of an exhaust leak? Even if they can it should have been recorded as not tested and failed on that.
