NOTICE
Whether or not cleaning has been successful can be seen from the char-
ging or flushing pressure and also from the exhaust gas temperatures.
If the cleaning process is unsatisfactory, it can be repeated up to 2
times.
If the cleaning result is still not satisfactory after three attempts and
the engine values are also unsatisfactory, we recommend that you have
the turbocharger inspected and cleaned by an official ABB Turbochar-
ging Service Station.
