Hi, wonder if any body can advise I lost some oil while recently changing my cv boot on a 2008 hdi manual 6 speed not sure how much, it was raining while I did the job and still is. I can't seem to find definite answers some say empty it and replace but that won't work also lead to believe they don't have a filler level. So how much of what oil and where to put it in would be very helpful. Ps car is at garage I asked them to do it but they haven't got time. :(
