Brake Fluid change - cost ?

Hi,



I am coming up on my first Brake Fluid change.



Does anyone have an approximate cost for this?



I can see some old E60 postings on BMW land, quoting around £110 ... I figure it will be higher now though.



I have an F10 520d. I will probably be having this done at a BMW Sytner garage.



Thanks for your time - cheers
