First of all, my brothers and sisters ... As it is known, I am a 2006 model x-design 206 user .. even though my car is gasoline, it sounds like a diesel ... I took it to the master, it said that the valve's setting has escaped. He pulled out a cable with a blue cap under the air filter in it, and he recovered, the car came to himself, because he could not send information to the ECU, and he said it was defective in the pressure sensor. Does anyone know about this sensor. Good night again?

The valve can be adjusted to the coverers in unfailingly 25 25 lira last year, it is the same now.

They told me about 60 liras in unfailing manner and is it reliable or not, what is the reason of the person?
