Electrical error on additional fuel level sensor. Voltage is to low.
â–¶ How to fix
* Check wiring (to additional fuel level sensor) * Check connectors (to additional fuel level sensor) * Check additional fuel level sensor * Measure the sensor voltage between signal (pin B17) and ground (pin B11)
What you'll see
No driver-visible symptom recorded.
System reaction
Functions dependent on the signals might be degraded. Examples listed below. -Fuel Level Display -Display instrument and simulated tachograph signals
Diagnostic depth
Detection
Impermissible signal from the additional fuel tank sensor. The sensor is faulty or voltage level is too low.
Possible cause
* Defect wiring - open circuit on pin B17 (signal) or pin B14 (sensor supply) - short circuit to pin B11 (ground) * Defect connectors * Defect sensor
