Just blanked off my egr valves, was having restricted performance on dash, and loss of power, and was told it was egr valves.
Car is a high miler, 2006 2.7 diesel, but still goes like a rocket, and i love driving it.
The only downside is amber eng. mgt. light is on now, but car is running great, been quoted £220 plus vat to remap and put light out, considering age and mileage, wont bother, will put up with the light.
Anyone else had any dealings with egr valves ?.
