    i put the 92 403 motor in and got a loom off a 92 403 auto and used my ecu out of 92 403and got a 92 auto computor 2

    i got it all going but the auto wont shift and the light on the dash comes on and it goes in to limp mode.

    the 2 plugs next 2 the fuse box both 25 pin dont match up

    the female plug off 94 has 9 pins in use but the loom i have the male plug has 13 on it

    would this be the reason the auto is not changin or will it be that im using the ecu motronic out of the 92 manual

    everything else is fine is there any 1 that has herd of a non vanos motor being used with a 94 vanos auto b4

    im new 2 all this so im sorry if i havnt worded it all right is there some way i can ad wires 2 the plug or something its doing my head in tryin to work out why its not shiftin and limp moding

    please help if u can shed any light on this for meee thanks in advance.........

    i have a whole e36 320 im wrecking 2 so any help and ill give u any of the parts u want 4 free i just wont my baby back on the road!!!

    Lets try a bit of text formatting!

    So which bit have you changed? just the autobox or the whole engine?

    I guess the N/V 320 manual was trashed, and you are reshelling this into a vanos auto

    There are some wiring diagrams there if you need them

    403 btw is the ECU code for a non vanos, and 413 is the Vanos ECU, but the 413 brother is only used on the 325. The 320 vanos used a Siemens ECU and a whole bunch of different sensors.

    het mate well i got the 94 320 single vanos but the motor in it was cooked so i pulled it out and put in the motor out of the 92 n/v,i changed both the computors and the loom 2 suit the now 92 motor.But the auto is the 94 model so the loom doesnt match up at the plugs next to the fuse box on the auto plug the the 92 loom has 13 pins in use but the the other half of the plug that runs into the fuse box witch is the 94 only has 9 pins in use..wen i go to drive the car the switch next 2 the shifter sport,econ and snow the econ light doesnt come on and it just stay in 1st gear but then i flick it in to snow and it shifts 2 second an thats it then the light on the dash comes on and it goes in 2 limp mode the red light on sports and snow comes on

    The way i see it, you have 2 options, one is swap the new car to manual, you certianly won't be the first doing an auto to manual swap.
    The other option is go through the wiring diagrams, and locate the differences between gearboxes.
    I imagine it might be a different gearbox / ecu that was expecting the Siemens 320 ecu on the other end, and the change is a bit too much for it.
