When i got back i lifted the bonnet and noticed fresh oil had come out from beneath the cap!
Having searched through posts on here i checked the O-ring to find it had kinked and split where it wasn't seated properly
I'll be off to the dealer in the morning to hopefully get a new seal. Beware in future that you should always check the O-ring is seated correctly before refitting the oil cap. Must be a common fault that they can work loose whilst the lid is being removed.

As for the level indicator??? Hopefully I've not over-filled it. I just put in about a quarter of litre as it was reading a little below the mid point of the level indicator.

If only 1/4L, you are give even if it says above max. Not enough to do anything, plus mine went back down to OK level after a bit
