I would be surprised if VW understood what you meant if you asked them to do this job. It's relatively easy if you follow the how-to guide on here, saves paying an hour of labour and a good way to get to know your engine. But I appreciate that not everyone wants to get into the engine bay with tools.
Have you considered using a local VW specialist rather than main dealer? For example, I live near AMD Tuning in Essex, they do all the same level of work (if not better) than a main dealer but it costs less. Plus they know most of the other things to check for whilst working.
