Motor swapped but wont start and electical error
Old motor had rod bearing failure
New motor has 77k on it. I installed it and used the engine wiring harness from my old motor as the new motor came from an auto e92. I did not touch anything on the inside of my car, only the engine wiring harness. Everything is plugged up and all bolts are torqued. When I open the door I hear a chime and I see the red car inspection image on the dash. If the car is on but the ignition is off, I get the following errors: A0B5 E5C4 A3AC A3AD A3AE A3B9 A550 With the ignition on, I get the following errors: A0B5 A118 E5C4 A3AC A3AD A3AE A3B9 A550 E597 A8AE A8AF E59A E599 E59C E594 E717 E71A E71B E71C E720 C90B C918 93FB What electrical error could be causing all of this? Also, my wipers come on as soon as turn on the ignition, I pulled the fuse for them for now. I hear what I think is the fuel pump when the ignition is on too. I am confused. |

If the wipers are going crazy and you are getting codes like that, its most likely you do not have the pins to the DME connectors lined up properly. They are small and the plugs can be installed a hole off without noticing.
