Sorry mistake my end. the VIN is SALLTGM873A824162
The reason the ECU is hard to remove is that I cannot see the two nuts to release the frame that holds to BCU and ACE to the body. I think I see one "mounting" JPEG. but cannot get above that as the two ECUs are bolted together. There may be a bolt to the lower left of the BCU that releases it. As I say nothing like the RAVE picture where the two ECU are apart by 3-4 cm.
I have taken a punt and ordered a cheap 2nd hand RQT 000030 ACE ECU off E bay. Nothing ventured nithing gained as they say
 
I've now flushed abut a litre of new green PAS/ACE fluid through the system. The reservoir is more green than black now.
Cant really do much more..........

Not really, however I am unfamiliar with this filter and as such unsure what consititutes dirty. Anyway it's very clean now.
Just reviewing what we've done that may have influenced the ACE system:
1. Swapped R13 and R14 relays.
2. Unplugged and pluged the ACE ECU main connector.
3. Cleaned the ACE block filter
4. Flushed through 2 litres of clean PAS/ACE fluid.

Update:
Did 400 miles over the last week. The ACE light came on 3 times during a period of 7 days. Various codes which when cleared took another 100 or so miles to bring up the ACE light again. Absolutely no change to the handling with the ACE light illuminated. I now have a replacement ACE ECU which looks in very fine condition and as such when I can find out how to remove the ECU cradle I will change them over.
More info as and when I get round to this.

So all I have done is change the ACE oil and cleaned the filter on the solenoid block and after a couple of hundred or so miles (in which the Amber ACE light came on a couple more times) the system settled down and now after eight weeks and 1200 miles the light no longer comes on.
Maybe it was because I bought a replacement ACE ECU ready to shove in that the system decided to behave itself? Or maybe it just needed an oil change?
