    Channel Not Available Error

    I was trying to compare the adaptation channels of the MIB2 (5F) module of 2 Audi when I found some channels value shows the "ERROR: Channel Not Available" message on one of the car.
    Granted the firmware of the MIB2 are different. But is there a reason why is the channel name available but not it's value?

    Here are the autoscans of the two 5F modules:

    An adpmap of the 5F on both cars would probably be useful?

    Not all channels defined in a particular ASAM data set will necessarily exist in every module covered by that dataset. Think of it in the context of pre-UDS modules; they had a fixed set of 256 possible adaptation channels and many modules had most of them "Not Available".

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
