Diagnosis on the Mercedes Viano turbocharger

The diagnosis of turbocharger faults is expensive. With a few tricks, you can do most of the tests yourself.

  • The most complex but also the most important test is the preassure test of the entire boost pressure system. In this case, a pressure of approx. 1 bar is built up via the turbocharger intake by means of a adapter. Leaks can be localized mostly directly and safely.
  • Checking the shaft play and visual inspection of the compressor wheel. To do this, the intake must be removed in front of the turbocharger. Then you can easily move the shaft of the turbocharger in the radial and axial direction with your fingers. When the compressor wheel touches the housing, the shaft play is already considerably too large. The blades of the compressor wheel must be complete and without any damage.
  • Checking the boost pressure control system. If the turbocharger is equipped with a pneumatic actuator, the actuator must be checked for leaks to ensure the function of the diaphragm. For this purpose, a vacuum can be applied. For electric actuators, we recommend an actuator test on a motor diagnostic device.
