For the last few days this warning light has been coming on intermittently - but as it came on this morning after only a mile from cold, I don't think this is the case. Could it be a faulty sensor or something?

It may be that your cat is failing. This sensor triggers at 600 degC and its only function is to alert the driver of the cat over heating.

Solved the problem - just put on a de-catted downpipe + centre section!
