S6 5.2 V10 Oil Leak???

Hi all, new to this forum as I have been having trouble with my S6 5.2 V10 avant recently  It looks like an oil leak has developed as once the car is warmed up and been driven for about 20mins, I get a burning smell and smoke coming from the back of the engine and from the drivers side wheel arch? The car still runs great no warning lights etc but I cant find the leak? A garage has looked and rekons it was a loose sensor at the back of the engine and they cleaned it up an re-tightened it but the problem is still just as bad? I dont suppose anyone has come across this on an S6 engine have they? or if anyone has an idea what the leak could be I would appreciate some advice.
Thanks in advance

Hi Glenn and welcome. If the garage is right, hopefully they are, then it might just be some oil left over from the leak dripping onto the exhaust or manifold burning off once it hits the heat.

Hi Colin, thanks for the reply and welcome, been out for a drive round today and think its still burning fresh oil? It seems ok as long as the revs stay below 2000rpm but above that the leak seems to rear its ugly head again! Bit sad having an S6 and staying below 2000rpm

Update on the oil leak, it turns out to be the gearbox sump gasket leaking, 370 quid to replace gasket and fluid, so hopefully this will resolve the issue fingers crossed

That's good news, nothing too major.
