Hi all, meriva b 2010 1.4 petrol, have a problem with engine light coming on, even after changing several sensors and both 02 sensors, any ideas please.

It could be an exhaust leak before the catalytic converter (oxygen level high)

Plug the exhaust by holding a rag firmly over the tailpipe and listen for hissing which would indicate a leak somewhere in the system.
