Tried 5-7 re starts but still showing

Anyone else had this problem. Search only comes up with EGRs however doesn't apply to me.

Any ideas guys?

If the light is on, there should be a code logged...

Probably a Lambda sensor

Had the same issue a month or so back driving to work got the RAC out who checked it and he cleared the fault which he said was a sensor value reading being different between the sensors on the exhaust so the car was running lean. He cleared it and touch wood not had problem again Freelander SE - Gone
S1 Elise - weekender
Rrsport S/C Autobiography 10 plate -well and truely here, but now stolen

Last time mine came on it was the cat

mines just come on, its the O2 sensors before cat - £100, job done  RR Sport Supercharged Vesuvius Orange 4.2 V8 First edition

Prefer RR Vouge S/C but they don't do Orange !

As D-M said if the light is on there should be a fault code. I've had the light on 3 times recently. First time required a new O2 sensor. Second time it was related to the purge valve, this came on after filling the tank and being stuck in traffic. After a bit of open driving cleared the code using my IDDTool and it never came back. And just now the light was on with a warning "Bank 1 running lean" after a 300km blast at around 120kph the light extinguished itself...

The above isn't much help though if you're not getting a gault code for the engine...

My light was caused by code P0430. The dealer replaced an O2 sensor and the left-side cat.
