Emissions warning light

[M.O.S]

This light has come on... I've read the hand book and it says a deterioration in exhaust emissions...



The car has recently switched from 95 octane to super unleaded. The exhaust is no louder or of a different tone etc. There's also no rattling coming from the exhaust.

Has anyone had a similar fault? The car has the standard exhaust/catalyst...

Thanks

i've had mine come on a couple of times.

the first time, it was due to a bad batch of petrol. the dealership tested the petrol in the tank, and it's ethanol levels were higher than they were supposed to be ... ran through that tank, and it eventually went away after a dozen or so starts.

second time, it was an oxygen sensor, which was deemed faulty and replaced under warranty (in the US they're under a ten-year warranty for being considered liable to fail).

could be the change in petrol, could be something else, is what i'm saying. not helpful. my dealership told me the first time to wait a week before coming in, to see if it was the petrol. which it was.

I agree with Dakini.

Also have a look at this thread:

It might also be worth your while undoing and tightening up the fuel cap, as this can occasionally cause the warning lights to come on.

I have a 2004 Mini Cooper and the service engine soon light has been on for a few years. I've had it in a couple times and they tell me it's just a fluke. It comes on for awhile and will go off for a short time. I took it to auto zone and had them put the tester on it and it's giving code P0130. I am wanting to sell my Mini and wonder if it's really a fluke or if the dealer has just been saying that. Could someone please help me.
