• Leak in exhaust system (exhaust-side cylinder head to post-catalyst oxygen sensor) Fuel presupply pump
• Rail-pressure sensor
• Camshaft position sensor
• Intake-air temperature
• Poor-quality gasoline

Terminal condition: none

Voltage condition:

• Onboard electrical system voltage between 9 V and 16 V

Temperature condition:

• None

Time condition:

• None

Other conditions:
