What does it cost to replace a timing chain on a V6 GLX Jetta Wagon

There is 115,000 miles on the car. After I got the motor mounts redone and the noise in the engine was the same as it was prior to the motor mounts being replaced. I replaced the motor mounts as a preventative measure. They hadn't failed, but the mechanic said it was time to have them replaced.

"the noise in the engine was the same as it was prior to the motor mounts being replaced" They are 2 entirely different problems , however , I would ask for a WRITTEN guarantee for the 'noise' diagnosis , make sure ALL needed components are replaced while it's apart!
