20k miles, 4 year service requirements

About to get my GTI serviced tomorrow and want to confirm what actually needs to be done (since it's low mileage)? VW said the spark plugs but from what I can see that's not accurate? Especially given it has such low mileage? From what I can see, it's supposed to be every 6 years? https://static.nhtsa.gov/odi/tsbs/2019/MC-10164263-0001.pdf
