As i mentioned in the other thread, knock during commute-type driving isn't really cause for concern. The DME is working to optomize fuel economy; AFRs are leaner, load is lower, timing is more advanced, etc.

The knock during WOT pull could be a sign your fuel isnt high enough octane. You can always try a 91 map.

It would also help if you posted your exact car specs (beyond 2014 335i), mods, fuel, etc.
