Hi everyone,
I have succesfully swapped an M52B25 engine from 323ti (05/1998) into 316i compact M43TUB19 (1999).
I needed to make an EWS delete, the engine is working perfectly now but the rpm and temp. gauge isnt working but I have found a solution to that (3 wires from x20 to x16 and x17).

What bothers me now is that the OBC shows consumption 0.0 L/km.
Does anyone know how to make it show real consumption? (I know about the test functions and obc test mode but that doesnt help me currently)
It seems like the OBC isnt connected to the engine. The clock works, outside temp works, avg. speed works.
Thanks in advance!!!
