I had similar issues with my 1.9. It was full when it was at the garage following some damage work), then after driving home, it was about an inch below the 'min' level, I took it back, no leak detected. Was fine at this level for about 6 months, when it got topped up again.
As long as it doesn't drop any further, you should be ok, but keep an eye on for a few weeks.
