you must have the euro 4 engine with the electronic egr valve,the eml will always be on because the ecu is picking up a lack of egr airflow fault code,some people have drilled a 10mm hole in the blanking plate which sometimes is enough for the sensor to detect some airflow and put the light out.

Yeah your right, drilling a hole defeats the object. I've read elsewhere that to over come the EML is to get a code reader which can be used to cancel the warning light. Try taking your blank out and unplug the multiplug, this will keep the valve shut thus acting as a blank. Is your car a mk3 by any chance?

you need to fool the ecu into thinking its still connected, clearing the light with a code reader only works for a few miles
