I've been going through all the work orders from the previous owner today and I would like some help in knowing what exactly was done in this specific service.

It seems relevant because ever since I've owned the B7, it has this loud ticking sound in the engine, and it looks like this may have been diagnosed in the service on this receipt for 9/22/15 which was less then 1 month before I bought it. Here's the work order.
