I was thinking of getting my auto gearbox oil changed, I have a 3.0TDI avant 2005 with 76,000 miles on the clock and I find conflicting info. Some say it is lifetime...and some say change around now. Lifetime seems to still mean a time scale but keen to know other peoples stories and if there is anything to watch out for when doing it as the garage I'm going to use it not an Audi specialist.
