I am looking for a quick answer about my EGR
shows me on the dashboard icon check engine sometimes
I checked with two computers, delphi and snap on
it shows egr fault but it does not show which one, but it shows the error of the egr sensor
I need to know if rd tdv8 is an option regeneration repair of these EGR Do I have to buy new
Thanks for help

If I'm understanding your post correctly,,, repairing egr valves,, never heard of this being done before always been a case of replace, unless it's the 2.7 engine and most people have them blanked off. Egr valves on the V8 are not so much of a problem as the V6 but whatever you have done bite the bullet and do both valves as if it's only one causing trouble now the other will follow suit not long after. 2010 RRS, TDV8

thanks for answer
whether the symptom of a broken EGR can be Black smoke under acceleration
or sometimes engine vibrations??

Black smoke when accelerating would be a split intercooler hose,, ( two big hoses on top of the engine) if you were to see excessive whitish smoke and / or lumpy idle on startup then I would suspect egr valves 2010 RRS, TDV8
