Hello Everybody,
Bringing back the THULE step issue. In order to avoid any future headaches, I have removed the step from my 2024 GC600 right after getting the van from the dealership. Soon I have noticed that if the vehicle was not used for more than 3-4 weeks, it completely drain both batteries, to the point when you have to unlock the vehicle's doors mechanically (battery completely drained out, not even the key fob works anymore)
At first I have suspected issues related with vehicle's many ecu's and controllers, so I brought the vehicle right back at the dealership. In my country the VW dealers do not sell too many GC's, so their tech knowledge related with the camper part is limited. But they escalated the technical issue to the factory tech-support, so they made an online diagnosis together with the factory tech-support. The answer was that the discharge is related to an issue of the THULE step (the factory didn't knew the step was removed, so they asked the local technician to check if the step was damaged in any way)
To make the long story short, I have reinstalled the step and the discharge problem was gone. But still I would like to uninstall this garbage, as I don't see any benefit having it.
The VW dealer cannot "undo" the step, so they do not have a procedure to remove this as it was never installed from factory. Of course, it can be removed mechanically and just disconnect the plug, this is a 15' work, but this leads to the electrical issue, as apparently the ECU that controls the camper module will stay awake and keep trying to close the step.
This means a current consumption of about 0,12A that will go on until the battery is fully drained.
Any thoughts?
