P06F1

Symptoms

• Check Engine light on
• SCR/AdBlue system indicator
• Unstable dosage of AdBlue reagent
• Overheating or underheating of the SCR control module
• Increased NOx emissions

Causes

• Faulty internal temperature sensor of the SCR module
• Loss of thermal contact between the sensor and the module body
• Contamination of the module housing, interfering with heat dissipation
• Internal changes to the SCR module electronics
• Incorrect sensor calibration

How to Fix

1. Read current temperature sensor data via diagnostic scanner
2. Compare readings with expected values under given conditions
3. Check if there are any foreign contaminants on the module body that impair cooling
4. Check the connection and condition of the module connector
5. If the readings differ from the actual temperature, replace the SCR module
6. Perform a post-repair SCR system check
