One customer gave feedback about his Autel Ultra Lite:
Mercedes C63 2008 (w204)
I tried to program new ECU (MED9.7) and during the flash I got write error. After that I managed to flash if with a different tool but then I got another error when trying to “teach-in drive authorization” with Autel.
Mercedes E220d 2017 (w213) – Initial start-up of 9g tronic gearbox was not successful. Programming and coding was successful but the last step (drive authorization) failed.
Here is the Answer:
After Unlock Transmission Protection, when it comes to Personalizing, you need to start the engine quickly and keep engine idle for 30 seconds, Ultra Lite will automatically go to the next step.
Done! Hope this could help!
