Customer Question

Hello, I have the Mercedes W220 S 430. It does not start the engine.
The car was about 14 days without a battery. After the new starter is purchased, it rotates the engine but does not start. Only the P1605 error code is displayed on the original diagnostics.
The actuators indicate: Engine control blocked - Yes
how should I proceed to unlock the engine control unit?
Thanks for every advice.
Yours sincerely, Radek
