Following an oil change a few members noted significant amounts of water in the gearbox which found its way into the oil via worn seals in the gearbox tower.
Others have noted very low oil levels which is a risk on s/h cars where the oil slick has been cleaned up without checking the source.
Any oil does degrade over time due to oxidation and moisture caused by internal condensation
All good reasons why changing the oil after a few years is good preventative maintenance
Regarding problems after a gearbox oil change, the only reasons could be
(1) use of the wrong oil ( the genuine Audi oil is significantly 'thinner' than the majority of regular 75w90 oils specified on many other car models and can result in a stiff gearchange particularly in cold weather.
(2) difficulty removing / replacing the fill and drain plugs resulting in damaged threads and possible oil leaks
