2015 c400 A3 service

How hard is the A3 service to do on a 2015 c400. Almost fell over when I herd how much the dealer wants just to install the spark plugs also what other services does this include. Can I also shut the A3 service light out Thanks everyone

C400
How could spark plugs be needed for a 2015 car? Isn't it more typical to do spark plugs well after 75k? I have a C400 as well and this sounds insane. These "services" are so cryptic and annoying. I am about to research this stuff because a lot of it seems so unnecessary. For my last service they changed perfectly good windshield wiper blades.

I believe that the 'hidden' menu allows you to reset the service code.

What were you quoted for the A3?

I don't know how much the C400 is tuned but I'm running about 20 pounds of boost on my R53 Mini and change my plugs about every 35k

I ran similar boost levels in my old SRT-4 Replaced plugs every oil change

my GTI had a few mods (Stage 2) and I replaced the ignition packs once w/ones from the Audi R8

Interested to see how the DIY C400 plug service goes
