I also recommend searching for local independent for alternative quote,
I was quoted £360 for a major service by my local dealers, car is a 2014 gti pp with 41,000mls, the car has always been serviced by vw previously, I’ve just had it serviced by a local independent ( autohaus Dolby ) in Sheffield £219 including pollen filter, great customer service, the car won’t be going back to the main dealers again.
