engines will tend to use oil when they are fresh, oil consumption will fall right off for most of the enignes servicable life then when it's knackerd it'll burn oil again.
it's not uncommon to get engines that haven't setteled during there initial running in period
this is basicly where the roughness on the bores has been polished off by the rings without wearing them enough usual culprit is engines not been worked enough to get enough cylinder pressure for long enogh to force the rings into the cylinder and make them wear, once the initial roughness is gone this wear still happens but at a much reduced rate higher cyl pressure encorage it to happen faster.
the mk5 thats sat outside used to use a littel oil when it new, think it used a couple of liters in it's first 10 - 15k it's never needed a top up since it's done 140k now
my old 1.8T passat had done 220 k when it died it didn't use oil
my mk2 golf has done 180k it dosent use oil ( used to when i got it )
the vans show it best of all tho. all of them that have been used for short trips and bimbeling around need oil toping up between services, the vans that do the rough heavy work and hard towing don't need topping up between services.
genorators also show the same trend. i've got a genset here admitedly it's about f**ked it's done 10,000 clock hours, in the last 500 hours it's started to use oil ( as it's dyeing ) it used to use a bit of oil but after about 200 hours of hard work it stoped useing oil and never need oil topping up between changes for over 7000 clock hours.
new ones never done any hard work ( standby genny ) it burns about 1ltr a day atm so it's ether knackerd @ sub 500 hours or going to stop useing oil at some point.
sounds like your audi was fit for scrap burning 1ltr ever 200 miles. i don't tolerate oil burning much it gets a chance to stop or it gets rebuilt
