okay so I got my 2005 ba mk2 turbo about 2 weeks ago from the dealer it has 77,000 on the clock and the turbo is rooted already I haave really only gave it one good boot since having it racing a mate and since that it will now and the make a grinding noise after around 2500 revs, when shuting down the car you can hear it grinding and I have also took the inlet pipe off to find it has alot of play fowards and back wards and side to side, it goes in to the shop in aa few day to get looked at and then most probably fixed , by warrenty thank god. so iv been reading everything so far and all I can think it would be is the car yard has not changed or checked the oil lines and filter or they have used the wrong oil. so I was just wondering if anyone has had a problem with the oil lines once they have replaced them with the stainless steel braided lines at all? or did this seem to solve the blockage? of course with regular services on the filter . and is there anything else I should be changing or checking once I get it back after warrenty . thanks .
