I got a powertrain malfunction the other day and my car went into limp mode. I guess this really saved the motor. Dealer calls me back and says that the EGR is bad and coolant was leaking, but it didn't do any damage. They told me that they can replace the EGR at a cost of $3,325. When I google EGR replacement, I get around $500 to replace this. Am I missing something?
