When warm on tick-over this car has a metallic screeching noise coming from the engine. Noise dissapears when revved and comes back strsight away on tick-over. When engine is cut off the noise takes a few seconds to dissapear. THIS is not a turbo related noise as the noise is heard from the front of the engine. All intercooler pipes and ancillaries have been checked to no avail. Engine management light indicated low inlet manifold boost pressure and the scanner indicates that the boost pressure is ok.
