Title: help apx wb conversion
Post by: Anto97 on June 14, 2022, 12:40:25 PM
hi boys
i am trying to do a wideband conversion for my audi tt with apx engine
I remedied the collapse of an ecu 8E0909518AA
with immo off the auto part but does not accelerate
it only keeps idling but if I press the accelerator it does not respond and with the engine off if I press the accelerator the throttle body "click" is not heard
having said this, how do you think I can solve the problem?
forgive my english :)

8E0909518AA is a A4 ecu, are you sure it will work with your engine?

Usually, if you have a APX/APY you would use a BAM or AMK file one BAM/AMK/AUQ/AUM something ecu.
Some of the longitudinal ecus will work but im not sure of your 8E0909518AA

Describe what you did, step by step to help you.

in practice I took this ecu I made it immo off and I tried to turn it on with the lambda probe disconnected and the car starts but if I try to accelerate it does not respond as if the accelerator was disconnected in diagnosis it gives me 4 errors on the can line that if I'm not mistaken the apx does not have and gives me an error on the throttle body

And what about ECM relay that give power to TB?

Why you dont read forum little more?

sorry I thought that all the ecu wb were quite equal to each other. do you think there is a way to get this blessed throttle body going or not?

You need ECM relay that will send power to 121 pin on ECU
It must be correct conected, otherwise it will not work.
Look at any shematic of WB ecu

is it possible that I have damaged the ecu wd after trying a start with the old probe nb attached?

thank you very much for the tips i added pin 121 with 12 volts under key and now the tb works all that remains is to do all the electronic adaptation ::)
