i have a question.. what is the best way to take care of an 2001 audi a6 that has 140,143 miles? Or should I say what is the minimum recommended maintence I have to do in order to survive a christmas trip to new york?

140,000 and it still runs? nice! I hope mine will

140,000 x2 before expected death...Change the oil, make sure all your fluids are topped off, check tire pressure, flush radiator and replenish coolant...with that you are good to go. AUDI's break because they are not maintained properly. Take care of the car and it will take care of you..There are plenty of older model AUDI's on the road pushing hundreds of thousands of miles. You should have no worries!!

thanks for the advice, now how do i need to know when to do that?

Follow the link in my signature to my registry page. There, you will find a link to the official Audi maintenance schedule.

140k is just run in there is no limit on how long it will last if you maintain it well
