Hey,
Few days ago I have swapped the engine in my late 99' E36 Compact. The orginal engine was M43TUB19 which has been swapped to (ofc) M44B19
However the mechanic wasn't able to get the instrument cluster to be fully functional. In the orginal (99') cluster the tachometer is not working anymore as well as the temperature gauge. Because of that he has mounted the older instrument cluster into my car that was working with M44 engine before. The tahometer is functional now but the ASC, ABS and AIRBAG lights never appear (even during the startup of the engine or when holding down ASC button).
The reason for that is probably the difference in construction of both instrument clusters. In my old (99') cluster, the tahometer was controlled by CAN bus while in M44 engine its controlled directly from ECU, on the other hand probably because my compact is so "new" the airbag and asc module is E46 type and they somehow can't communicate with older type of instrument cluster.
Have someone found any solution to that problem? I have both instrument clusters..
