Hi!
Unfortunately, the script for resetting the service interval, which is included in the current version of VCDS 17.1.3.0, does not work on my Octavia 1Z either.
Therefore, I manually reset the settings in the instrument cluster menu and then it displayed 372 days or 15,000 km until the next service.
Resetting via VCDS (select control unit 17, then adaptation 10).
IDE00342-WIV: Resetting the WIV: The reset did not result in any changes.
The relevant values:
IDE00512-WIV: Minimum Km for Performance/Inspection.
IDE00513-WIV: Maximum value for Km/inspection interval.
IDE00514-WIV: Maximum value for the time interval between inspections.
were grayed out and "not functional."
Switching to SIA or WIV: IDE00492-MAS02003-WIV: Coding for maintenance interval extension status. WIV or SIA = SIA or WIV enabled.
and switching between SIA and WIV: IDE00492-MAS02006-WIV: Coding for maintenance interval extension - selection of WIV or SIA = WIV.
It also didn't achieve anything.
I noticed that the oil quality automatically resets to "bad" after a reset: IDE00492-MAS02012-WIV: Coding for maintenance interval extension - oil quality = bad.
The solution is simple:
1. Reset (IDE00342) or directly via the control panel interface.
2. Change the oil quality to "good" (IDE00492). Of course, only if "good" VW 507.00 oil has been filled...

)
The values will then be automatically generated.
IDE00512-WIV: Minimum Km for performance/inspection = 15000 km.
IDE00513-WIV: Maximum mileage for maintenance/inspection = 30,000 km.
IDE00514-WIV: Maximum value for the time between inspections = 744d.
active/editable
Possibly add more...
IDE03351-FIX: Distance traveled since the last maintenance inspection based on mileage: 0 km.
IDE03352-FIX: Time since last time-dependent inspection: 0 days.
In the instrument cluster menu, the value "---" appears (for the first few hundred kilometers) for both the time and distance until the next service.
