My engine light is illuminated and I know from diagnostics that the problem is a lambda sensor - I believe there are 4 of these.
I would ask if any knowledgeable member has directions to locate and change these. As additional information I note my fuel economy has gone down.
The vehicle recently had a comprehensive servicing and runs very nicely apart from the annoying engine light displayed.
Have ordered the following sensors
43-9G444-AB petrol sensor
LNE1682BC oxygen post cat sensor
My plan is to change these and see if the problem is cured.
Any advice would be gratefully appreciated.
