Hello Alan,

Not sure if its applicable to yours but was the software updated after the solenoids were changed? I wasn't brave enough to tackle the gearbox dismantle so not sure of the wiring routing inside the gear box. is the control box on top of the gear box still aligned as I understand that the "fingers" that select the gears can be misaligned. Are all the other leads in proximity to the gearbox securely connected?

Had the same gearbox in a Citroen Xantia 1.9td was beautiful until i got snow and sports lights flashing together! didn't get around to swapping the solenoids as it spent more time in limp home mode. Apart from which if I had swapped them for new ones, I told that only the dealer could put the software on or a gearbox specialist.

Only know about the "black box" gear selector as mine had one installed before I purchased the car.
