I was wondering if 2002 2.7t a6's have the dreaded oil sludge problem. Also, my car is at 58,700 miles and i know youre not supposed to do the TB replacement until 70 but i heard that the timing belt in these cars can snap going down the road just from being 6 years old? Anyone heard of this?

 

sometimes it can go at anytime i know that from my friends having a tt's and a4's and one of my teachers has a A8 and his snaped at 50k miles but i mean i would get it done asap.. im getting mine done this thursday and im just getting to 160K..best car ive owned yet.. and maintainence is worth it.

 

never heard of many sludging problems but timing belt isnt necessary until 70+k ... if you have the money to get it done then i guess do it but ur 99.99% ok at under 60k unless you have been beating the car since it was born

 

got her at 58k so who knows :-[

 

id say ur good to wait a lil but if it snaps dont ask me to pay for it lol

 

how much to change TB?

 

looking at about $1200 to do the TB and water pump. The pump also goes bad causing leaky fluid. Its just another thing to do. I would recomend getting them both done, but if the pump is ok then I guess you could wait.
