How to Remove the EGR on a Mercedes 300D

Mounted to the intake manifold on the back of the Mercedes 300D engine, the EGR valve is responsible for recirculating any exhaust fumes back through the engine to be burned a second time before being sent through the exhaust pipe. The Mercedes 300D EGR valve is connected to the engine with two bolts and can be removed in just a few of minutes. You can save time and money by removing the EGR valve yourself.

Instructions

    Unfasten the two bolts on the sides of the EGR valve with a socket wrench that secures the part to the engine.
