Too short service time

[Sipos]

My A6 was serviced one month ago with 135.000 km using long life 2 oil and now after I drove 1100 km is showing already that I have only 9500 km to go till the next service. Started counting downwards from 15000 and now is showing already 9500. (driven only 1100 km in normal way).
Any idea why could be this?

Think it sorts itself out after a while. My new A6 (6 weeks old) is set to variable servicing and was suggesting a service in 7200 miles when it only had 1000 on the clock.....it's now 9600 miles and is creeping up.
