So I found you . . . .

1) The fuel tank MUST be removed & completely cleaned before going any
farther. Both WH an MBDOC have stated that unequivocally.
2) The engine wiring harness MUST be replaced after cleaning the gas-tank.
3) Check the battery! A low battery will cause random DTCs to be set. If it's been sitting for 4 years, it may need replacement?
4) After those tasks are complete, you can read some stored DTCs and post them.

I would recommend that you reset all codes first and then read them after a few days.

If you don't attack this problem in the recommended manner, you may never solve it!
