With our new L33 construction delete version, the DPF display error as well as the DEF system error are fixed.

If the soot level was already high, it must be reset with service advisor.

You must disocnnect the DPF fuel dosing valve as shown in this manual: John Deere DPF fuel dosing valve
You can disconnect the DEF pump, but it's not mandatory.


After making sure everything works fine, the DPF has to be drilled/removed.
