C5 Break III Steering faulty + Parking break faulty after valve block change.

[Coney]

Hi all,

these past 3 months I have been trying to fix my automatic transmission which suddenly turned weak in reverse.
Changed solenoid valves, cleaned block, been in and out of it quite a few times and have some routine by now.

Got a new block from China now, put it in, and am now facing the above messages upon turning on the ignition.

Lexia simply says:

- gearbox communication error
- power steering electric pump unit communication error

The only thing I can think of that these two have in common is the connector holding several plugs but it appears okay, and I hadn't disconnected it.

Can anyone think of something else that I may have touched that these two have in common?

Think I just found a likely candidate myself just now:
