2012 audi a6 timing chain replacement cost

The kit itself doesn't cost that much, but I believe its the labour that will rack up the majority of the bill
Timing chains usually last longer than belts do in most cases (Damn you, B6 S4!)
Also, see repair breakdown by problem area and cost
2L V8 gets a bad reputation for reliability primarily because of the commonality of timing chain failure as well as the cost to replace the timing chain components
