That's the fixed service schedule version. The VIN stickers of all 3 of my Octys specified variable service. The dealer changed it programmatically to fixed for the MKI but Gretta and the MKIII were programmed to match the spec on the VIN sticker. Once you change the oil the car tells you when it wants it done again. I always done both at 20,000 kilos and generally reset it but I let the MKIII run on once and it asked for oil somewhere between 25,000 kilos and 30,000 kilos, I can't remember the figure now but it didn't get to the specified maximum of 30,000 kilos. However, I have reduced it lately to every 15,000 kilos because it's regenerating the DPF far too frequently and I read on one of the fora that can cause the oil to get diluted with diesel. Greta has always been done on 20k intervals and doesn't consume more than 0.27L between services. The MKIII does consume oil and always has, probably over 2L between services, that's probably down to the heat required to regenerate the DPF, seemingly all VAGs with DPFs consume a bit.
