Disabling Opel / Vauxhall Z16XE EGR Valve

EGR Valve - Exhaust Gas Recirculation Valve.  

The EGR valve allows your vehicle to more effectively and completely burn up fuel mixture by recirculating a part of the exhaust and running it over the combustion process once more. The EGR valve regulates a smaller passageway amongst the intake and exhaust manifolds. Once the valve opens, intake vacuum takes in exhaust via the valve. This leads to a cooler, considerably more complete burn of the gasoline which reduces you car's dangerous emissions by prohibiting the formation of certain harmful gases.
