Hi.
My wifes Renault scenic 1,9 DCI year 2008 is very slow at low speed, bad acceleration.
After nearly 1800 rpm the turbo kicks in and manifold pressure increases to up to 35 psi.
I have checked the vacum pipes for the waste gate.
I have replaced the MAP sensor and the pressure regulator valve for the wastegate.
The MAF reads 13-50 g/sec at 800-2200 rpm.
Engine load reads 80-100% in idle speed and I don´t know why.
Any good ideas?
