Hello guys, I used DIS and got some error codes from the controllers.My check engine light is not on but i have these codes in the memory.Can this 4CAE EGR position sensor code effect the fuel economy.Should i take it to the dealer to fix this error.Wondering why this code didn't trip the check engine light.

Need advice please.Thanks

vehicle is E70 2009 X5 35D with 76000 kms
