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
