Ok have a issue that I think may be the transfer box on my 2014 X4 F26 3.0d, theres a knock, knock on acceleration and same again just as pulling up. its also happens on hard acceleration. as though the chain in it is taking up slack trying to catch up if you see what I mean. cruises just fine and the gearbox is smooth as, ive check obvious things like drive shafts and joint and cant see anything there. but it bloody anoying and spoiling the car
I now have got into the habit of trying to drive around it. it need a experts to look at it to confirm and to get it done.
Can anyone surgest someone cluded up with the X drive in Yorkshire area.
Thanks in advance and be gentle with me, im new to this "Forum" lark

Hey did you ever get your transfer case handled? I have the same exact issue on my x4. I want to know if I should get the case changed or not, or just change the fluid.
