Yes, as with any car. But you only need the service done there. Any fault finding or rectification work that they feel needs doing, and you need to pay extra for, can be done elsewhere.
I get my Audi serviced by a Skoda dealer. I have found them very good as they are Volkswagen Audi group authorised and half the price on labour. They only use genuine VAG spares and oils. However, I would think twice if I owned a Quattro although Skoda now have a four wheel drive car. I will have to ask them in 1200 miles time!
