I’m starting this thread because the current configurator logic around the MY26 electrical options is no longer self-explanatory and may even be inconsistent.
As of 23 March 2026, my saved Utility configuration still showed these three electrical items:
• High-load auxiliary switch panel with roof sockets
• Additional power points
• Power Take-Off 400 W
A separate “Winch preparation” did not yet appear in that configuration.
Now, in the current configurator, the electrical section is presented differently:
• Additional power points = standard equipment
• High-load auxiliary switch panel with roof sockets
• Winch preparation
• Power Take-Off 400 W
The description of “Winch preparation” now reads that it includes front and rear high-current pre-wiring plus the rear NATO socket, and that control and power supply are provided via the high-load auxiliary switch panel in the roof console. That is where the confusion starts.
According to Rok_Dr’s manual supplement, EXT4 on the optional high-load auxiliary switch panel is the circuit for the rear NATO socket and the winch. It also states that from MY26 onwards, the rear NATO plug and front winch wiring preparation connected to EXT4 are now a separate option. So far, that still sounds logical: Before MY26, NATO/winch were apparently included in the high-load option, whereas from MY26 onwards, they are separated out as an independent option.
But the current configurator behaviour is what I cannot reconcile. In some configurations, if the high-load switch panel and PTO 400 W are already selected, “Winch preparation” cannot be added. In other cases, selecting “Winch preparation” leads to a warning triangle on the high-load switch panel, and clicking it opens a dialog saying: “Deselection required. The following option needs to be deselected: Winch prep.”
That is hard to square with the technical description, because the winch/NATO function is explicitly described as being controlled and powered via the high-load auxiliary switch panel. So my question is whether the configurator currently shows a dependency incorrectly or not? Is there an actual technical incompatibility with another option, possibly PTO 400 W?
At the moment, my working assumption is this:
• pre-MY26: NATO socket and winch prep were bundled into the high-load setup
• MY26 onwards: they are formally split into a separate option
• the current configurator may not yet reflect that split cleanly
TL;DR:
Since MY26, the rear NATO socket and winch preparation no longer seem to be automatically included in the high-load auxiliary switch panel package, but are instead listed as a separate option.
The problem:
The configurator behaves inconsistently. Sometimes “Winch Preparation” can be added on top, sometimes the system tells you it must be deselected again, even though the option text itself says that control and power supply are provided via the high-load auxiliary switch panel.
My open question:
For MY26, is “Winch Preparation” partly already contained in the high-load switch panel, or simply mapped incorrectly in the configurator?
If anyone has a solid dealer explanation, order logic, or technical documentation on this, that would be very helpful.
