Hi 
 
	so i am new to the jaguar world and have had my XF-S a few weeks now and had the fuel filter and sensor changed as had the water in fuel warning light,   it is a 10yr old car 
 
	now the drivers door window is playing up.  goes down fully but is playing up and sticks going back up. is this a common thing,   the rest of them work perfectly 
 
	also its done aroind 65,000 miles do i need to chnage the belt/chain/pump at some stage ?
 
	and recommended gear box service ?
 
	cheers
