EGR Valve for TDV6 Engine of Discovery 3/4 and Range Rover Sport
One of the common problems we fix with the TDV6 engine from Discovery 3, Discovery 4, and Range Rover Sport as the vehicles get older is EGR valves – Exhaust Gas Recirculation Valves.
The EGR system is a method that has been developed by engineers to reduce emissions from engines. They open only at idle, and at full throttle, to allow some of its exhaust gas to be diverted into the intake manifold.
When the valves fail, they stick open, and are open at other times the engine and management system are unable to work properly with. The symptoms are that your car loses power, and blows black smoke. The vehicle will register an EGR fault as well when this happens. We keep EGR valves in stock so we can get customers on the road the same day they strike a problem – we change both valves. There is some wrestling to be done working with a complex layout in a tight space, but it is a relatively quick job.
