Hi there ,

Ok the first thing that needs to be done before going any further is to get the exact fault code that is logged as this is IMPERATIVE to correctly diagnosing this issue

The most common issue we see is a fault code of P0420. - catalyst efficiency low
This is a partial or complete failure of the catalitic convertor

If this code is logged the catalyst MUST be replaced
We don't see issues with lambda sensors on this Varient

Without a Fault code you are working Blind
