Intermittent Engine Management Light

2003 Vauxhall Vectra 2.0 TDI
Car: Vauxhall Vectra
Year: 2003
Variant: 2.0 TDI
Categories: Running Rough, Starting & Power Loss
The Engine Management Light comes on intermittently. Therefore putting the car into "limp" mode. The light does go out by itself or if your turn the ignition On and Off.

Garage charged me £45 to tell be it was either the Intercooler or Turbo. Not cheap items and with no guarantee of fixing the problem.

Starting with the cheapest solutions my thoughts are hoses, sensors, wiring.

Any input gratefully received.

cold weather will have affected the small rubber elbows that connect the vacuum pipes on the front near the radiator. These pipes give vacuum to the boost solenoid. Common fault on the vectra.
Change the small rubber elbows and the solenoid should get vacuum again, thus making the turbo operate as before.
