the egr valve is used to lower emissions at certain driving conditions :)

it is not fitted to the usa version of the z22se.

with the egr valve costing as much as £150 + fitting at the dealers it becomes an expensive 'white elephant' when it fails :(

blanking off the egr valve can help prolong the valve's life, a faulty valve throws an eml [warning light on dash]

the 'egr cheater' is used to replace a faulty valve :)

you don't gain any performance from blanking the egr system, but it does stop exhaust gases re-entering the engine [which cannot be good]

It will pass the mot fine without the egr.

vauxhall do remove the egr valve on some cars when it fails, but it depends on the model/year of the affected car :roll:
