Hello! Having problem with my audi a4 1.8t 2002, i have changed oil and external oilfilter. The problem is that when i accelerate the gears are slipping a little while it doesen't matter if i have D in or are changing gears in manual mode. Otherwise the multitronic runs well, i have no faultcodes have checked with vagcom. (oil have been changed at 60000km,120000km and now filter and oil at 145000km)
