i worked for mitzi and the gdi engines had a light that showed when you are driving around in eco mode witch ment the egr was open

pepole drove them with the light on so much thinking they were saving money that they choked up and required the head to be taken off and cleaned up costing them more than they saved in fuel


with an egr engine you need to stop cokeing up by giving the car a good blast every now and then to clear out the shite
