Nissan

Dealer scanned my car and found that i need two items replaced (egr solenoid valve and egr bpt valve). i checked the hood diagram and discovered that the car has three egr components. ( egrc solenoid valve, egr- bpt valve and an egr valve). after one month of check engine light being on, it shut off on its own, and has stayed off for two weeks.should i try to repair only one of the two components suggested or should i look into repairing all three?

The most common problem is the bpt (back pressure transducer) hose look for a hose off the bottom of the egr valve leading to a metal tube the hose rots from heat.nissan master tech.
