Hi everyone, new to the forum. I bought my 2015 xc60 in January and it has 52k on the clock. It's due a service and booked in with the dealer on Monday but the discs and pads were looking worn so I've replaced them myself rather than paying dealer prices. When underneath I saw oil all over. After cleaning it best I could and then taking it for a run, it looks like it's coming from the front crank seal. Is this a common problem with these engines? And any ideas how much I should expect to pay for it sorting? The 2 year service alone is just shy of £500.
