Phoenix L4 — John Deere 6850, 6420 and 6620
Phoenix L4 is a John Deere engine controller. This catalogue indexes 16 software versions from 2008 to 2022 — John Deere 6850, John Deere 6420, John Deere 6620, John Deere 6920, John Deere 6820, John Deere 6910S, with the 12.5 L, 6.8 L and 4.5 L.
On John Deere machines we solve AdBlue faults inside the engine ECU: AdBlue injection disabled, level and quality emulated, the NOx sensor emulated, the fault codes erased for good, and the torque, power and maximum speed limits removed — no countdown timers. This applies to Tier 3B and Tier 4 machines with AdBlue, from Tier 4A to Final Tier 4; on older machines without AdBlue each version page lists what can be done on that exact file.
Every software version below has its own page with the vehicle it belongs to, the solutions available for that exact file and a price calculator. Read the ECU, find your number, open the page.

Questions about Phoenix L4
How is the job done?
The workshop reads the fault codes that restrict power, torque and speed, reads the file from the engine ECU and sends it to our file service; the after-treatment program is corrected directly in the ECU.
Which fault codes are removed?
The AdBlue-related codes that restrict power, torque and speed on John Deere, including 3516, 3517, 3556, 3597, 3719, 3720, 3936, 4077, 4334, 4341, 4343, 4345, 4360, 4363, 4364, 4366 and 5298. If other codes appear, they are removed as well.
