ACC sensor in Audi

Hello,

I'm looking for two radar sensors that have been removed from Audis. The sensors are made by Bosch, and one of them needs to be an LRR2. The Bosch documentation includes the CAN messages that the sensor should be sending, but it's not sending them. He sends other data, and that data only appears on CAN1 of the sensor, while nothing appears on CAN2, even though the Bosch documentation indicates that the measurement values should be present there.

Question: Does anyone know the Audi protocol for the ACC sensor?

Hello,

While I don't have any experience in this field, I find it totally fascinating.
Do you happen to have a link to the Bosch documentary?
And from which Audi models do these sensors originate?

Greetings.
Jens.

Sensor CAN channel 2 is likely a private CAN channel.
You'll probably have to "start" it first.

What kind of IDs are transmitted on CAN1?
