Diagnostic tool for turbocharger and crankcase pressure for VW vehicles

Description

• Diagnostic quick test of crankcase pressure, exhaust back pressure and pneumatic boost pressure control possible without OBD tester.
• Measuring the crankcase pressure
  • The Leitenberger diagnostic tool for turbocharger and crankcase pressure measurement offers you the opportunity to measure the crankcase pressure in a simple way. Increasing requirements and increasingly complex vehicle technology in particular make it essential to check the pressures while driving. Our diagnostic tool is able to measure the pressure in both the negative and positive ranges to an accuracy of one millibar. The supplied adapters for the oil filler neck allow the pressure measurement to be carried out in almost all cars. Additional special adapters can be ordered without any problems.
  • Problems with the crankcase pressure are often manifested by oil loss at the turbocharger. The increased pressure causes resistance in the oil drain line of the turbocharger, which means that the oil can no longer drain freely back into the oil pan. The oil is then forced through the turbocharger into the exhaust system or intake line, even if the seal is intact. If filter elements are fitted, oil mist can enter the intake upstream of the turbocharger via the exhaust hose of the crankcase ventilation system.
• Measuring the exhaust back pressure
  • You can also use the turbocharger diagnostic tool to measure the exhaust backpressure during operation. This measurement is very important, as you often cannot rely on the values read out in the engine control unit. Due to the design, the differential pressure sensor may display a value that is too low, which is unfortunately incorrect. This is precisely why it is very important to determine the actual pressure again with a special measurement.
  • Excessive exhaust back pressure can cause damage or even failure of the turbocharger. Excessive exhaust back pressure causes temperatures in the turbocharger to rise, which puts enormous strain on the turbocharger material. This also increases the risk of coking oil and an oil fire in the bearings. Furthermore, axial thrust occurs on the turbine shaft, which results in increased wear of the axial bearing in the turbocharger, up to bearing damage or total failure of the turbocharger. Oil leakage can also occur on the compressor side due to the uneven pressure conditions. This results in unclean combustion and a very sooty engine.
• Testing the pneumatic boost pressure control
  • With the turbocharger diagnostic tool, you can not only measure the crankcase and exhaust back pressure, but also check the function of the pneumatic boost pressure control. The hose is disconnected from the turbocharger control box and the pressure gauge is inserted into the system using the T-piece supplied. The control pressure of the control box and the function of the vacuum pump or solenoid valve can then be checked. This check is also possible while the vehicle is in operation.
