Why Does the EGR Valve Need to Be Replaced?

The EGR valve directs a portion of exhaust gases back into the combustion chamber. This lowers the combustion temperature and thus reduces nitrogen oxide emissions. Over time, however, the valve can become clogged or stick due to deposits. Then it needs to be replaced.

How Do I Replace the EGR Valve?

The exact procedure varies depending on the vehicle model. In general, however, you must first disconnect the battery and expose the access to the EGR valve. Then you loosen the bolts and connectors of the old valve and remove it. The new valve is installed in the reverse order.
