Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

As I have had no check engine warnings, they've suggested to perhaps give it another 3 months or so and interrogate again, but this is a new one on me and other than knowing its related to the catalytic converter in some way I'm a bit non-plussed on this whole issue.

The excellent indy dealer Northway has told me probably not to worry for now, they think it might have just been out of spec(?) possibly due to an unrelated starting problem which can cause the mixture to run a bit rich when the engine finally fires (they think that's a variocam solenoid problem by the way).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 1 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi All, Just had my car back from service - mostly good, but there were a few unexpected (intermittent) Oxygen sensor faults picked up in the diagnostics log. The excellent indy dealer Northway has told me probably not to worry for now, they think it might have just been out of spec(?) possibly due to an unrelated starting problem which can cause the mixture to run a bit rich when the engine finally fires (they think that's a variocam solenoid problem by the way). As I have had no check engine warnings, they've suggested to perhaps give it another 3 months or so and interrogate again, but this is a new one on me and other than knowing its related to the catalytic converter in some way I'm a bit non-plussed on this whole issue. Thoughts from the floor please?

POST 2Original post

It would be interesting to know the actual fault codes, but I think Northway are right to say don't worry for now. Assuming they weren't sensor ageing or failure messages, the sensors will also report occasions where the mixture has reached a lean or rich limit. I suspect that these are the faults stored, and will be caused by something other than the catalytic converters. These codes will not trigger the Check Engine light on a UK car, but will store a code in the fault register. The "problem" may be transient, so I think it is sound advice to leave it for a few weeks and run the test again. However, if you notice any changes in running characteristics, get it checked sooner.
