Checking Boost Pressure With Manometer While Test Driving the Car: Repairs

WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.

If the test values differ from the above values, read off the DTCs from the EMS 2000 system.

NOTE: Fault code ECM-2D will be stored due to the disconnected turbo control valve.

Check the turbocharger inlet and outlet system for leakage, blockage and unusual noises.

Check that compression, spark plugs, timing, fuel pressure, lambda, CO content, etc. are functioning correctly/are correctly adjusted.

Check that the correct fuel octane is used.

If the boost pressure is correct and well adjusted but there is still power dissipation, first try a new EMS 2000 ECU and check the performance again.

If the result is the same, there is an internal fault. Replace the turbo charger.
