Work Order Description

Nominal Value

Preliminary Diagnostic Check (Visual Inspection)

The following test steps must be performed in the given order. If a fault is found in one test step, the subsequent test steps can be skipped.

Function Checks

• Verify mechanical system functions/components
  Vacuum supply system
  (leakage, blockage)
• Check intake system/charge air hoses for leaks (secondary air, porosity and blockages)
• Check charge-air cooler for leakage.
• Check the hose clamps at the intake-air system / charge-air system for correct fitting.
• Check connected hoses and tubes for kinks, damage etc.
• Check air filter for fouling and correct mounting.
• Check air mass meter for fouling.
• Verify mechanical system functions/components
  Exhaust-gas turbo charger
  Exhaust system

After successful test/fault repair proceed to the next test step

Check: Pneumatic Components

• Ignition OFF
• Disconnect vacuum hose from following component:
  Vacuum pump
• Connect vacuum pump MKM-667 (component side) to:
  Vacuum pump
• Engine idling

Indicates the vacuum pump a value between -70 kPa ( -0.7 bar ) and -100 kPa ( -1.0 bar )?

Check: Pneumatic Components

• Ignition OFF
• Connect vacuum hose to:
  Vacuum pump
• Disconnect vacuum hose from following component:
  Vacuum Actuator - Boost Pressure Control Valve
• Connect vacuum pump MKM-667 (hose side) to:
  Vacuum Actuator - Boost Pressure Control Valve
• Engine idling
• Select the following Functional System on the diagnostic tester:
  Electronic Diesel Injection System EDC 16C9/16C39, Z 19 DT, Z 19 DTH, Z 19 DTL
• Perform the following Actuator Tests:
  Boost Pressure Control Solenoid Valve Test
• Press soft key ACTIVE

Indicates the vacuum pump a value between -50 kPa ( -0.5 bar ) and -100 kPa ( -1 bar )?

Check: Mechanical Function

• Use the vacuum pump MKM-667 to check the following vacuum-operated actuator for proper operation:
  Vacuum Actuator - Boost Pressure Control Valve

Test okay?

Check: Mechanical Function
