Increase ratio for windscreen washes : headlight washes. 5 is default.

Variable is 730 days or 18700 miles whichever comes first. 18700 miles equates to 30000 km. The distance / time to next service can be viewed in the following infotainment menu from memory: CAR>>Setup>>Service.
However, a word of caution - of the 4 main dealer services (all variable) only one has been reset correctly to correct time / mileage (Bristol Street Motors, Darlington top of the class!).
If you want to see miles / time since last service this can be viewed via VCDS (note - distances in km to nearest 100 km). I only found this out recently after a nameless Seat dealer failed to reset properly on 2 occasions so managed to do it myself in under 10 mins.

Yes. Use a trim removal tool (or flat blade of knife / screwdriver wrapped in masking tape to avoid scratching plastic). Place tool in the gap between overhead console and the rectangular pice of plastic that contains the two circular clear lenses and the submarine LEDs. As you insert the tool the rectangular cover will prise apart from the console - try tool along the 2 short sides (left and right) first, then you should be able to pull down. If the car is cold inside warm the plastic with a hair dryer first so that it is not brittle. Once lenses are off, blow to remove spider so you don't leave scratches / finger marks.
If struggling try searching for one of the inerior LED threads.

CAR >> Setup >> Mulifunction Display. Then make sure oil temp is 'ticked'
