Hello all
Sorry if I did not search for an answer properly but this is breaking my balls..
Here it goes. On my m50b25 coils 1,2,3,5 and 6 will spark coil 4 does not swapped coils from cylinder 4 to cylinder 1 and it worked but the coul from cylinder 1 on cylinder 4 did not, checked with a multi-meter and all wires going to the coils have a 13. something voltage. Any ideas on what to check for next?
Some one told me is the ecu. Found one a 405 but mine is 402
This is the info on the 405
Years Body Model Motor Bosch HPN DME Version
8/91 E34 525i M50/B25 0-261-200-405 M3.1
and this is the info on the 402
Years Body Model Motor Bosch HPN DME Version
9/91-8/92 E36 325i/is M50/B25 0-261-200-402 M3.1
looks about the same can I try that one? what other things could be the problem here?
