Last year the engine light came on and a mobile mechanic diagnosed the rear lambda sensor needed replacing so it was. He cleared the fault light but after a few days it came back on, he said the front sensor had now gone wrong and this often happened when one is replaced. I struggled to believe that and kept meaning to post on her for advice but never got round to it. I got the A2 for the wife and she uses it so little other things took priority.
However it's now failed the MOT on:
1. Exhaust emissions carbon monoxide content at idle excessive [7.3.D.2c]
2. Exhaust emissions carbon monoxide content after 2nd fast idle excessive [7.3.D.2b]
3. Exhaust emissions Lambda reading after 2nd fast idle outside limits [7.3.D.2b]
After searching here the remedy appeared to be replacing the front Lambda, which I did. The EM light cleared so I thought I'd solved the problem and took it in for another test.
Sadly it failed again on the first 2 points, so replacing the Lambda only solved point 3 from the first test.
The inspector said it might just need redex and a decent drive to clear the exhaust (which would fit with the car only having done very short journeys for the last 2-3 months).
On the way back home the Engine light came back on...grrrr
A local garage hooked it up and reported:
17559 No script 7566 sender for inlet manifold pressure g71 implausible
17584 Bank 1 lambda connection Rear Cat control limit reached.
Anyone want to offer some informed advice to point me in what now needs to be done?
Forgot to mention that it's a 1.4 2001 petrol
