Hey Guys,

Got a 12/2004 A4 B7 Avant 2.5 TDI. All the windows will stop working randomly at times then magically all working again. Doing this a few times so am changing the Comfort control module of BCM unit.

What are the differences between the model codes? I originally have 8E0959433BH. But can I use 8E0959433AJ? or 8E0959433AE or 8E0959433BJ?

What are the differences? does anyone know?

Thanks heaps
