been confirmed, it is advisable to check the good state and
efficiency of the watertight joints and the hose joints in the
air filter and intercooler before carrying out the checks on
the turbocompressor.
• Also check the state of the air filter - replacing it if it shows
any signs of wear, or if any doubt exists to its correct working
• Check the hoses are not obstructed, deformed, bent double
or worn out.
• If the turbocharger damage has been caused by lack of
lubrication, check that oil conduct pipes are not obstructed,
deformed or flattened. Replace if any doubts exist to their
correct working.
