Turbocharger: compressor/turbine
During operation, a fine adhesive dust is deposited on the inner air-carrying parts of the turbochar-
ger and this can progressively lessen the performance of the compressor. For cleaning the compres-
sor, see the operating instructions of the turbocharger in book C.
• Daily cleaning of the compressor end
• For periodic washing of the turbine end, see A5.05.06.00.nn.

Charge air cooler
• Check the permanent drain of the charge air manifold
Note:
A manual correction of the charge air temperature control is only necessary in speci-
al cases.
If there is water in the charge air manifold raise the charge air temperature until wa-
ter condensation is stopped.
• Electronically controlled thermostat valve: raise the temperature by adjusting the controller.
• Diaphragm thermostat valve: raise the temperature of the water or reduce the flow in the low-
temperature circuit by opening an external bypass.
• Observe the maximum permissible exhaust gas temperatures after turbine, see exhaust gas
temperatures after turbine.
• If the quantity of emerging water is not reduced despite the temperature rise, check the
charge air cooler for leaks.
