Should be £199 at a SEAT dealer now. They introduced a fixed price for this a while back.
Interesting that the servicing costs differ between VAG brands. The servicing costs are obviously part of the overall brand position and value metric for each individual brand in the group.
£175 at Skoda, £184 at VW and £225 at Audi
I'd just take my car to Skoda and tell them to do it!
