Hey guys, question? I was driving my 2007 ram 2500 yesterday and at 67,500 miles the perform service light came on in the overhead console. Now I know that the EGR valve and cooler and all is to be serviced at this mileage . Now back at 56,000 and some the turbo blew and all the EGR stuff was clogged and all that was serviced. My question is would the light come on automatically at 67,500 miles or is the egr crap really need to be serviced with just about 12,000 miles? Thanks
