The site is basing the recommendations on the standard VW specs for those years and also where the car might have a DPF or long life servicing. As far as I am aware, the Ibiza won't have a DPF, so the site is recommending a 507.00 oil as it may be on a long life service schedule. If it's not on a long life schedule, there would be no issue in using one of the 505.01 oils in that as well.
Hi Tim, I'm due an oil and filter service on my seat leon FR TDI 2004. I'm going to go with the millers XF as recommended above. I seem to remember that you used to do a filters service pack for these, but they don't appear to be available on your website, but the filters are available separately. Any chance you could do a forum deal please mate?Hi
That is a good oil for them.
