Title: Can i swap ecu's over 96 16v
Post by: mat-ryder on 01 June 2009, 13:14
I think my ecu on my abf is shot and i wanted to know if its possible to swap the ecu and key over from my other abf. do i just need the chip from the key and the ecu?

Yes plus I think you will also need the ring around the ign. switch.

You can swap just the ECUs but it will need adapting using VAGCOM or other.

Could swap it over, wth the ign ring and key.

Why do you think its your ecu? Have you had it looked at?

I have tried everything, its really starting to p!ss me off now. I replaced the crank sensor today cos the wiring on it was shot. i need someone with vag-com to plug it in. i did buy a lead but i can get the drivers to work on it, tried everything once again. when i swapped the ecu before without the ring it would fire up for a second so it makes me think its the ecu....

Might go and buy a vr6 lump and be done with it

you need the transponder box, key and ecu. ring doesnt hold anything special so that can be left alone.

don't think you need the transponder box.i have 3 diffrent ecu's and they all work through the same loop and transponder box  just the rfid chip in key that matters

if you swap key and transponder box along with the ecu it doesnt need recoding with vagcom, mat says he cant get it vag-com cable working so needs to do it this way ;)
Also says with ecu swapped car starts then dies which is an immobilisor fault.

I beleive if you just swap ecu you can recode the matched key and transponder box to the new ecu as cs98sss4 said :)

edit: I saved this text from clubgti somewhere, this is how you adapt a transponder box to an ecu apparently:

Quote
To Adapt Immobiliser:
Go to 'Immobiliser' Module in VAG-Com,
'Adaptation'
Then 'Read'
Wait a few seconds, and press 'Save'.

To Adapt ECU:
Go to 'Engine' Module in VAG-Com,
'Adaptation'
Then 'Read'
Wait a few seconds, and press 'Save'.

Do both...and all works well.
I've swapped them about many times. Never a problem.
This just seems to mate the immobiliser to the engine ECU.

Cheers guys. Im gonna have one last attempt at sorting it out this weekend and if it doesnt work i willbe ripping the whole lot out and dropping in a vr6. Any one know what i need to run an OBD2 VR6 engine. Obiously the engine, ecu, loom and coilpack but is there anything else, i.e will i need the part of loom that runs from the obd plug socket or will this be attatched tothe engine loom?
