To keep it short I have no boost (targeting 20psi getting 0) it wasn’t overnight and I’ve been at 7 psi for around 6 months with no time to fix it, now it’s completely at 0. I have got codes 2C58 (Charge Pressure control: switch off as consequential reaction) and 2d55 (variable camshaft timing control (VANOS) intake, cold start: not controllable). I have also noticed my fuel economy is significantly worst and around my vanos harnesses it is caked with dirty debris. My question is, would this code cause me to have 0 boost psi?
Anything helps thanks guys
