Im about to do my timing belt with almost 90,000 miles on my 2002 a6 2.7T. Wondering if there are any other problem areas or common maintenance that I should consider doing now while I have everything torn apart. Im thinking of getting the timing belt kit off ecs tuning called ultimate plus... heres the link... Audi C5 A6 Quattro 2.7T > Maintenance > Engine > Timing Belt Kit > ES#2569851 ECS Tuning Timing Belt Kit - Ultimate Plus With Gates Racing Timing Belt - 078109119JKT2
