Hi Stevey,
Yes it is where the engine connects with the gearbox. I have a 6 months gold warranty with warrantywise so hoping they will cover this work if it is the crank seal. If anything i will get a full report after the check from audi to confirm where the cause is. Then make a decision after speaking to warranty bods. Also do you have any contacts that have done this sort of work at a reasonable price incase i end up getting fobbed off?
