	DQ250 (MQB) Wakeup « on: October 21, 2021, 01:17:24 AM »

Hi,

I'm trying to access to a DQ250 with VCDS. I connected the ECU over "Antrieb-CAN" with a MQB Gateway and the Gaeway with OBD. All Power Supply is on (KL15, 30). I send the KL15 Wakeup on "Komfort-CAN" with ID 0x3C0

I can access the Gateway and see that Klemme 15 over CAN is "on". But the DQ250 does not response. Any clues?

Thanks.

Check CAN termination (i think DSG does not have resistor inside) or make direct conntect with VCDS to DSG, then you also check termination.

Hi,

thanks for your reply. As I connected TCU to GW there should be a termination inside. But anyway - I added a Termination Resistor but no change.

- Check AntriebsCAN at TCU at all: are there any IDs
- Check Klemmen_Status_01
- Check Network-Management

But also, TCU should be reatchable, if you connect VCDS directly to AntriebsCAN
