While doing a scan under INSTALLED modules I get message during the scan stating:

Address 28: Failed to respond

This is the rear HVAC which I do have on my 2008 Touareg T2 with the 2+2 HVAC system.

I noted that under address 8 I can preform all the tests (fan motors and servos) for the rear HVAC there so thing seem to operate but find it rather curious that the address 28 is present but not accessable. With the recent repair of a servo back there the DTC related to that servo disappears from address 8 and was never mention in address 28...cause it was never accessable.

Mind posting the scan? Even if you didn't explicitly save it, if you're using a current version of VCDS, it will be in your Scans sub-folder.

I'm using VCDS-Mobile so I'm not sure if this impacts the question. I don't know what a "Scans sub-folder" refers to but if you you mean deeper into the system for address 28 it fails with a time out error. YOu'll see in the gateway it seems happy but in the detail of the scan you get the communcation error.

28 is a slave of 08 on this car (you can see "Climatronic Fond" there), so no issue with the car. We should look integrating the "skip address" function into vcds-mobile at some point.
