If your exhaust leak is before the lambda sonde this might be the cause of engine warning note since a leak will suck in fresh air along with exhaust passing by the lambda measuring point, making the ecu adding more fuel as it thinks it is running to lean on mixture.
This again is making it hard to controle on the mixture as exhaust leak will deliver varying amounts of air pass the lambda. Regardless it results in higher fuel consumption aswell.
