I currently own a Volkswagen Golf 1.6 se match 03 plate, of recent the 'yellow warning/emissions light' has came on, the mechanic stated that the 02 sensor needs to be replaced. There is also a rattling noise when in idle and at low revs, when I accelerate more and get into higher revs the noise is no longer there. Is this a symptom of an o2 sensor of which needs to be replaced? Or could this be something completely different?
Many thanks for your time
