I removed and replaced the J605 module on my Phaeton today, this is the slave controller that operates the trunk opening and closing mechanism on Phaetons that have the hydraulic servo operated trunk opening and closing feature.
I could not find any information in the existing Phaeton CD about this controller. No luck doing a search on the controller number (J605). Also, I think you should include adaptation instructions. When this controller is replaced, it needs to be adapted. This is a pretty simple process, but it is not documented.
