Trying to determine small oil leak

[LexFire]

Hey you wonderful lot!
I've been lucky, the A2 has given me barely any issues, however...
Last time I got under the car (after an oil change) and after cleaning, I noticed a small leak coming from what looks like the join between the dipstick tube and sump. From memory it looks like a black plastic bit (dipstick tube?) and the silver metal sump.
Does this ring a bell to anyone, and if so is there a fix?
Looking at a few threads I've noticed people have replaced the dipstick tube, was the symptoms the same as mine?
Any help would be appreciated!
Cheers

The dipstick tube seals to the block with an O-ring I believe, replacing this would probably be easier than sourcing a new dipstick tube.

Alternatively, as you say it was after an oil change, it may just be drips from when the oil filter was replaced, this tends to dribble oil down the front of the engine when removed in my experience.

Cheers Indi,
My first thought was if an O-ring had perished/failed, just didn't think to check at the time.
I am almost certain it wasn't caused by excess oil from the 'outside', I have noticed a few drips on the driveway after i have topped up oil through the front access panel, but did couldn't trace any leak from that, only from the dipstick join.
I will get under and have a loo and feedback. Hopefully i have a correct sixed O-ring lying about!
