^thats extrmely rare and extrmely lucky to have a warning like that.
I’m sooooo glad I’ve had this done already…and not on my dollar. But if you check out this thread a lot of you guys should breathe easier http://www.audizine.com/forum/showthread.php/475041-Who-has-the-highest-mileage-S4-(2012)! I wouldn’t replace unless there is a failure or if motor is pulled anyways.
I hope JHM has their built motor program together within the next couple years. I’m not going to do much else until they get that rolling. Replacing the timing set would be a good excuse to get your motor pulled and oh might as well do headers and get it built and get s/c… 
Anyone with the RS4 having timing related failures?
^^^hope not!
Many components on the B6 were improved upon in development of the RS4, then implemented on the B7 S4. i.e. 2006-2008 S4s get a bunch of stuff earlier cars didn’t. Some 2007 cars got stuff 2006 cars didn’t. Etc. Hopefully the updated timing components from the B7 cars prove stronger.
I have a pricelist for all of this stuff from an Audi dealer here in Canada if anyone is listed. He basically took 20% off retail on every part.
