AL4 Automatic Gearbox Software
 

Hello,

I will be changing the two Electrovalves within the AL4 Gearbox on my 2003 Citroen C8 2.0 HDi Auto to the Borg-Warner PE257416. This requires the upgrade of the Gearbox's ECU Firmware (software) into a newer version. I don't know if my current Firmware is compatible with the Borg-Warner solenoids or not.

My current firmware details are:

Supplier: Siemens
PSA Reference: 8200302005
Software Reference: 9654868580
Supplier: 04
System: 92
Application: 08
Version: 1A
Version: 1701
Message System Number: 00

I have a Lexia (clone), I know if I have a dealers log-in access I would be able to update all the firmware on my car, but I don't.

What is the latest firmware for this gearbox and how/where can I download the various firmwares?

Simple.

bonjour si du a la valise lexia tu peut vérifier si ton firmware est compatible avec ta boite al4 pour des électrovannes borg-warner normalement il est bon si ton c8 est de 2003

si tu change les électrovannes .change aussi les 2 joint noir qui se trouve derrière le blocs hydraulique en bas sais impératif pour un bon fonctionnement de ta boite

Thanks olivier plusquellec and kitty-hawk, After posting the issue, I realized that I placed it in the wrong section, hence posting it again.

However, this was an issue that took a long time to solve. At the end, a little extra oil (250 ml overfill) seem to have solved it..

Thank you for your advice and help.
