Measurement Block 13, 09 Central Electronics

Hi,

"Recently, I've been having a problem where my engine's idle speed sometimes goes up to 1000 RPM and then drops back down after a while..."
The error codes all indicate that there is a problem with the voltage. So, I checked it out, and the voltage is all within the normal range (approximately 12V without the motor running, and approximately 14V with the motor running).
Another symptom is that the rear window defroster is no longer working (it's blinking), and the seat heaters are not getting warm.
It is supposed to be the case that non-essential consumers will switch off starting at 12.3V.

Okay, I've done some more digging, and then I saw the following in the "Central Electronics (09)" section, specifically in the measurement data block. (see attached Screenshot)

Ah, I thought so... Thank you!!
That means there's a mass airflow problem with my control unit, right?

Best regards.

Wait a minute, there's an inconsistency in the label file. Either the STG isn't seeing the reference mass, or the setpoint range is incorrect...

I'll check my car sometime and see what information is displayed.

Okay, in my label file, it states a voltage range from 5.00...17.75 V.

Best regards.
