You need fault codes to be read.
As you know the DPF fill level it will have been on diagnostics.

It's not limp mode if there is no fault. Something may be broken/not working properly which means you are down on performance but that isn't limp mode.
No one can help remotely, so I suggest you find someone that knows how to diagnose and test. Just blindly fitting new parts isn't the way to go.

That isn't a Mercedes specific fault code.
You need to Google the code for whatever reader you are using for a description.

Better still, find yourself a Mercedes specialist with STAR diagnostics which can pinpoint the exact problem.
Generic code readers cannot always do this.
