In the workshop the state of the turbocharger can be checked briefly.

Of course, one should begin by checking current data read during a road test

Derived boost pressure control, pressure control solenoid boost, etc

Of course you can check the status of the compressor wheel after dropping air duct.

Once the turbine is a little more difficult, because little can be seen without dismantling the housing.

You can also assess the impeller clearance, but his assessment requires some experience.

Besides, you can check the operation of a relief valve or the variable geometry - if it works smoothly and in a full range of motion.

Next - oiling the compressor or turbine.

The problem is that very often occurs, and not always accompanied by damage to the turbocharger :)

In fact, only a verification of the turbocharger is its demolition "to smithereens". The problem lies in the fact that when these turbocharger needs to

be regenerated or scrap :)

I like 1.9 Diesel engines, better than 2.0
Never let me down
I do prefer classic cars
Less stress and cheap to maintain
