Default 2004 D3 ABS issue from bad to worse

Some of you know from another thread that for sometime now my D3 has had issues with the ABS controller ECU and a single wheel speed sensor failing to report once the car warms up, and generates an electrical fault in circuit error.

So today, I dove the car to an as yet unnamed establishment although at least one forum member knows where to get the ABS ECU removed and repaired.

Fast forward a couple of hours and the car is started in the workshop having been put back together but its obvious something is wrong. They then spend at least two more hours taking things apart and rechecking.

Things are now a lot worse than before, I've gone from having an intermittent (the car needs to warm up) ABS wheel speed sensor fault to a hard ABS error as soon as you start the car.

I've now got this error

along with

Invalid being reported against all the wheel speed sensors in VCDS

The ABS, traction control light and a flashing red (!) in the speedo and one flashing in the top left of the widescreen DIS

plus when I get to 20mph I get a parking brake error which remains on until I slow to a stop only to beep and return again at 20mph.

I've not named the establishment yet as they are working with me to fix the issues. As they are 1.5 hours from me, I needed the car to get home otherwise they would have carried on working on it tomorrow. They are going to call me when they have some news to get the car back in, but they are currently saying the electronic module may need replacing but they did not know about the parking brake error.

I'll attach a VCDS scan once I have redacted the VIN number. I have cleared all the faults from this scan, only the ABS fault and parking brake return.

I drove the car home, leaving them at 5.30pm.
