Normal behaviour, no malfunction
Turbocharger Minor uniform wear around the periphery of rotor components,
caused by slight local rubbing of adjacent components, is
permissible. The compressor blades and turbine blades are
then shortened somewhat. Certain tolerances must be observed
to avoid a significant loss of efficiency.

If there is any doubt about the extent of rubbing, then an ABB
Turbocharging Service Station must be contacted.
 Have a dimension check carried out by an ABB
Turbocharging Service Station.
