The corrugated section is wiring harness (to the crank sensor) the dipstick tube is above the pillar that sticks out from the sump - check to see if the tube is in the sump and bolted in place, from the wiring it looks like it may have been disturbed.

Thanks for the information.
Will try and get it up on a ramp ASAP and take a look. It really isn't easy to get to to see though

Thank you very much for the schematic.
So looks like it could be the seal (no.5) that's the culprit unless there is a split/break in the pipe?
Should probably order items 5,6,7,10 and 11 then to be sure🤞
Hope Audi still have them.
Has anyone actually replaced this themselves?
No I haven't but I have done the dipstick pipe. I checked my manual for instructions on removing the oil filler pipe and found nothing other than pull it out at the top. I assume therefore it is an easy task.

It looks like the sump may have been off at sometime. The factory sump sealer is quite neat and consistent. Some unevenness on this car.

I would be surprised as it had one owner for around 10 years or so and with full Audi main dealer service history before we bought it 5 years or so ago but I suppose you can never be fully sure with any used car
