Hello everyone,
An overseas client of mine has shortly ordered a spare part (Motor controller/ Interface Board) for his ETV216 2013 Model. Part number was 51169229. Now that he has finally received it and was trying to installing, he keeps receiving the above mentioned error (0802).
So he tried to get smart and removed same part from a similar Reach Truck and the machine worked without an issue. The part I have supplied him is brand new and doesn't have any issues.

Following that, he contacted Jungheinrich service who sent him a technician to do a diagnostic and again, his Judit (Diagnostic equipment) didn't read the part either. Adding to that, he mentioned that the Reach Truck has another similar part with the same number but installed underneath the Hydraulic. He finds it too weird that both parts have the same number, which is something I never noticed before and doubt is a manufacturing error.

Does anyone have an idea of what the issue could be and how to get around it? It is a hassle when a client orders something specifically and is half the world away, while we cannot review the real issue.

I appreciate your feedback.
