dippy_x: Only 1 of my 7 TDIs have ever used an appreciable amount of oil between services, and that was a 2005 MK5 GT 140TDI PD. It was run in by driving it down from Lookers in Burnley where I bought it (broker buy), to my dad's house in Southampton, where we went on the Southampton to Le Havre ferry. As soon as we were on French soil, I had the amber warning for low oil. The oil was on the bottom of the dipstick and took a full litre to get to full. A few days later, the car was driven back up to Newcastle. So the car spent its first 700 miles on the motorway, sitting at 75mph in 6th. Not ideal running in conditions.
That car used a litre every 2k miles.
As far as VW are concerned, unless the car is using more than a litre of oil every 1000 miles, they don't see an issue.
How was yours run in?
