2015 Engine Knocking/Pinging under load

[Jnemjo]

The Service Adviser at the dealership told me the pinging I was hearing was nothing like when you hear pinging from a gas engine. He said what you are actually hearing is rattling from one or more injectors. I did find lots of information on rattling injectors. Apparently it's not that big a deal. Their is a company out of Germany that specifically rebuilds injectors that don't rattle but they are pretty expensive.
