If it be­comes clear that the tur­bocharger is not op­er­at­ing as it should be, a di­ag­nos­tic test should be car­ried out as soon as pos­si­ble. Early signs of trou­ble in this re­gard in­clude a lack of power from the en­gine, pos­si­bly ac­com­pa­nied by a high squeal­ing sound from the fail­ing tur­bocharger bear­ings.

If caught at an early stage, it’s pos­si­ble that a re­place­ment unit may be all that’s needed. If the prob­lem is ig­nored, the tur­bocharger can com­pletely let go, tak­ing the en­gine with it.

Tur­bocharger fail­ure is par­tic­u­larly com­mon in ex-fleet cars, which of­ten have doubt­ful ser­vice his­to­ries. As we have of­ten pointed out: skimped ser­vic­ing al­most al­ways re­sults in se­ri­ous and ex­pen­sive prob­lems fur­ther down the road.
