B7 Timing chain

[harley141213]

Hi

I’m currently looking at B7 rs4 and have been reading as much as possible re potential and costly problems, DRC, discs/brakes, oil cooler etc but haven’t found anything about timing chains.

Is there a recommended interval for changing the chain? What sort of cost is it?

most of the cars I’m
Looking at are around 90k miles so it would be good to know if a chain change would be on the horizon.

thanks
