HI, I just wanted to add to this thread, as I've had problems also with the ecall feature on my 2020 Scala. When I did a scan I had the following codes:
1)
2566
HEX(A06)
B105413
000
VAG-Text: GPS antenna Open circuit
DTC-Text: GPS-Antenna - Interruption
Fehlerart: Circuit Open
2)
13631561
HEX(D00049)
B200049
000
VAG-Text: Ctrl. module faulty
DTC-Text: Control unit defectiveAnalog circuitry
Fehlerart: Internal Electronic Failure
The open circuit fault triggered at the same time that I saw the yellow warning on the dash. The open circuit fault is now passive and the e-call button has the green illumination so appears to be functioning. I always have the "ctrl module faulty fault" in the memory, I asked the dealer and they said that there was no fault which puzzled me!
In case anyone has something similar here are the ECU details:
SW-part number: 5WA035282
HW-part number: 5WA035282
SW version: 0083
BL-version: 0025
HW-version: H14
