I don't know how much I'd trust a dealership diagnosis, they're not always the best at diagnostics. Not a bad idea to get a second opinion from a trusted independent shop.
It's not hard to rule out something like the timing belt tensioner with a mechanic's stethoscope or long screwdriver. Touch it to the area the tensioner sits in and see if you can hear the ticking from there.
