Just noticed slight hesitance at around 5k rpm when giving my E39 530i auto the beans, either in high gears or lower gears going up hill. Could it be due to me filling the tank with 99 RON this morning when the last two tanks were 95?
Got the VANOS seals to do, but I don't think it's that. Any ideas?
