Got a fail on my mk2b 1.2 8V on exhaust emissions, high idle test1 and test2 generated a lamda 1.07 and 1.06 respectively. It should not be more then 1.03.
I replaced flexible pipe and rear box prior the MOT test as the flexible part was rotten inside and the exhaust made more noise then normal. After the replacement everything was OK, apart of small leak between cat and flexible pipe joint.
Apart of high lamda reading, CO and HCC levels are well below the acceptable reading.
I am going to have another go to try to fix the leak. I am trying to use a ring gasket rather then a flange as the exhaust I fitted appears to need a ring gasket. I have two questions.
1. Will complete seal of the leak fix the exhaust lamda emissions readings?
2. Any more suggestions to seal that joint?
