Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Hello folks, Just got a 07 Cayman few days ago and now I need to go through some of the issues it has and one of them is a buttons by the drivers door for the front trunk and rear trunk The issue is - they doesn't work. And while I'm pretty certain why the button for the rear trunk doesn't work (I need to replace the rear control module under the driver seat, and if you are selling one - let me know ), I can't logically describe why the front button doesn't work. Here is a dilemma - button on the keyfob opens the front trunk. Lever in the front trunk boot - opens the front trunk. Based on the schematics the front trunk release button is connected to the network control module, which is connected via CAN to front control module. I did go ahead and connect the diagnostic tool. Besides the scanning it has some actuation tests. When I connect to the central network module and read the status of the button - it changes from inactive to active when I press the button. So the button works and definitely send the signal to the network module. When I connect to the front control module (in the front trunk) and send the command to open the latch - it opens. When I check the status of the button in that module - it always shows inactive. So it kinda doesn't receive the "open" signal from the central network module. But it receives the signal from the keyfob and opens the front trunk. Ideas - it is a central network module that doesn't send signal to to the front control module or it is a front control module who doesn't "hear" the signal from the network module? Or is it somehow related to the rear module (that I need to replace) that technically have nothing to do with the front trunk latch? Ideas?

Read through this thread from another board - I think you’ll find some useful info in this thread as the OP seemed to be pretty technically inclined. https://********.com/forums/987-981-forum/1110823-dead-battery-help-up-creek.html Hope it helps.

POST 3Original post

Ended up replacing the rear control module with a used one from Touareg (20 times less expensive than Porsche ) and the button started to work. Apparently the rear module is necessary for the front button to operate for some reason.

Care to share the part number for future reference?
