Door locks are another weak point, often freeze so you can open the door but they wont stay closed when you want to drive off until warmed up, certainly a characteristic 😆
I have just fitted a full set of EBC RedStuff pads to my 2012 XF-S using Pagid solid discs and there is definitely less brake dust and a much better bite when the disks are cold (a disappointing side to the OEM pads)
they were £150 for all of the pads with next day delivery
