It’s a service report from January this year of a 2016 1.8 Audi TT TFSI sport that I’m looking to buy, however I’m not sure about the wording of this report in terms of the ‘front brake discs slightly lipped’ and ‘rear discs corroded’, as it then goes on to advising changing at 100,000 miles (car is currently at 74k) - but is this just referring to the screen wash and spark plugs?

Should the discs be done much sooner? I’ve read that brake discs can be slightly lipped and cause no problem until they begin nearing their minimum thickness, as well as rusted discs not being a major issue and can be rectified with more frequent car use? But I really don’t know anything about this myself, so just wanted some clarification before potentially buying this car
