Timing belt Replacement (tensioner stud)

[VagCabby]

Posted this in the C6 section but got no response

I'm going to be replacing my timing belt in the coming weeks on my 2010 A6 C6. Engine is a CAHA common rail 2.0tdi 170. I'm not shy about carrying out my own work on my cars but the amount of posts i read about the tensioner stud snapping after the belt being replaced.

I've got a genuine Audi timing belt kit and water pump, the kit doesn't include the stud for the tensioner, just a new nut. Question is should i buy the stud and replace or just fit the new nut and torque up as per spec? So many mixed answers on forums, some say leave it some say change it, nearly every post i come across is a failed PD tensioner, never the CR engines.

I replaced the wife's BKD PD 2.0tdi timing belt 2 years ago without replacing the stud(hadn't read the horror stories then) its running fine with no issues!

I don't normally replace the stud when doing timing belts. I do torque every nut/bolt to spec that has anything to do the timing belt just in case. Haven't had any issues so far.

Thanks. I think I'll leave it then and just torque to spec. At least with me doing it myself i know that it's torqued up properly and not under strain. Just so many threads about them snapping after a 2nd or 3rd belt change, although most of these are from people using garages to replace the belt so no idea if they had been torqued up correctly

I think if I got to the 3rd belt change I would consider replacing it. Certainly not for the first.
