I am trying to help a friend diagnose a fault with his car. In the last 4 years it has been running fine with the last issue being a coil pack failure in 2014. Issues: EPC Light on: Check engine light comes back on after clearing codes. (EPC Light never goes away) Car has no power, won't really rev, no boost. Idle is fine, MAF seems fine (readings look normal on Live Data). The following codes come up as soon as you start the car after clearing the codes: P0444: - EVAP Purge Control Valve (N80): Circuit Open P0033: -Turbocharger or Supercharger Bypass Valve Control Circuit P0243 :- Wastegate Solenoid A - No Signal P2295: - Fuel Pressure Regulator 2 Control Circuit Low P1573: Left Engine Mount Solenoid Valve Open Circuit Its almost like the N75, DV etc are not getting power.. (Replaced the N75, but no change) Has anyone come across this before? These faults all occurred at the same time and constantly come back as soon as the engine is started.
