Dismantling and Cleaning the EGR Valve

Model: Saab 9 3 MK 2 - Years 2002-2014
Part: EGR valve

Many devices are used to reduce harmful emissions, including the EGR valve. The recycling of exhaust gases (in internal combustion engines) involves recirculating a "small" portion (5-15%) of the exhaust gases from the exhaust manifold to the intake manifold to reduce pollutants present in the exhaust gases. Remove the engine cover and locate the valve, then disconnect the connecting pipes by removing the hose clamps. Using a socket spanner, remove the securing bolts at the base of the valve. Carefully remove the valve from its housing by rotating it back and forth until it comes free. Once extracted, you can either replace it or clean it using a brush and appropriate solvent. After cleaning, refit the valve.

Replace the damaged bulb with a new one (same size and voltage). Refit the light into its housing (push it in with your hands until the metal clips are fully locked). Test the light's functionality before completely refitting the piece.
