Query maintenance intervals for VW T5/T6 via CAN-Bus

Hi,

I'm looking for a way to find out the maintenance interval, i.e., the mileage until the next scheduled maintenance, for a VW T5/T6.

Ideally, someone would know the CAN ID and the specific bit.
It would also be helpful to know whether this information can only be read via OBD, or whether it is also available via the comfort CAN bus.

It should be the case, as the display needs to provide the information for the "Service in xxxx km" message. However, it's possible that the values are only transmitted for about 20 seconds after the ignition is turned on, since the message on the display disappears after about 20 seconds.

Thank you in advance to anyone who can help me here .

Hello Rapha,

The value is not transmitted via CAN, because, as far as I know, the instrument cluster itself calculates or stores the maintenance intervals.

That's why he's also being reassigned to the service department.

Will the value then be output via OBD?

He is queried at the combination instrument, and the method of querying varies depending on the vehicle model.
