When throttle is released: rasping noise from the engine compartment

If the above-mentioned defect is detected, it may be related to a defect in the vacuum system responsible for controlling the turbocharger. If the test shows that the vacuum is leaking of its own accord, the defective components are to be replaced.

IMPORTANT

This defect may also occur in other models with the same type of engine.
Please always follow the repair instructions from the vehicle manufacturer when carrying out such work.
