3315419 - 1064AA Check turbo presure

Connect the pressure transducer between the intake air chamber and fuel pressure regulator.Position the Examiner/SDC diagnostic instrument in the interior compartment and make the connections.On the Examiner/SCD, select the 'pressure gauge' instrument and set it to acquire data in 'intake pressure' mode with full scale 2000 mmHg and time selection 10 seconds.Go out onto the road (observing the legal speed limits) and carry out the following test. On a stretch of motorway, drive the car at 2800 rpm in 5 ^th gear. Start graphic acquisition by pressing 'start' on the diagnostic instrument, and after about 2 seconds press the accelerator pedal fully until 3800 rpm is reached.After reaching this speed, release the accelerator pedal fully.Display the resulting graph and in the pressure constant part (*), excluding the initial peak, the reading should be about 2000 mbar corresponding to a turbocharging value of 1000 mbar.
