Had this pop up on my car today along with engine light... some internet browsing suggests this is a fault that simply requires a reset but that means the warning should be ignored? If anyone shed any further light it would be appreciated

Mine does it every now and again.
I just clear it with an OBD reader.

Mine also does this from time to time. Clears itself eventually (within three drives).

On the V8 it’s often the O2 sensors that show up as faulty. Never replaced them in 6 years’ ownership and the engine never exploded or anything.
Just clear the error code with a cheapo OBD reader

Certainly I would recommend clearing it with a cheap odbc reader as above. If you get one that links to your phone I find it useful to screenshot the error for future reference.

If the message keeps coming up every few days/weeks for the same o2 sensor bank then it is probably an o2 sensor nearing end of life, they are around £75 to buy and relatively easy to install if you are that way inclined.

I have found that putting different brand fuel can sometimes cause the error message. Other than that its just what they do lol.

Presumably the car’s driving ok?

I’ve had the same issue which also turned out to not be an issue. The code I got back was something like P1869D (though I may have that a bit wrong - will check). That code references something to do with the clutch, and AM Cambridge confirmed it’s just a thing that happens and with the faults cleared is nothing to worry about. I’m not sure if there’s any link between the emission warning and the powertrain / clutch code, but there you go!

I’ve also heard that not screwing the fuel cap on properly can cause the emission service warning, by the way. Worth a check.

Yeah car is driving fine I certainly can't sense anything diff to before the warning came up. Anyone recommend a suitable ODB reader for the job?

A £15-£20 one off amazon, free odbc reader app for your phone, is enough for this sort of thing.

Funnily enough this warning has cleared by itself as some suggested it might!

Often it can just come up if you are idling a lot or stuck in traffic

a good run and a few re starts will then clear it

glad it worked for you

Not to worry you too much but I got a new clutch along with all the ancillaries fitted under warranty due to a persistent emission warning light that for some strange reason was triggered by the clutch. Over £5k's worth of work.

Worth bearing in mind.

Yup, SS3. Thanks for that. I’ll keep myself alert. How many miles was yours on and can you remember the fault code? Mine has a year of warranty left.

Time for new sensors?
