Gentlemen,
my interest in these issues stemmed from the hydraulic pump 30Amp fuse blowing continously on my Ace, caused by a seized pump motor;
plus the problems people have with the ECU unit. I looked around for a new pump and found that Audi and Peugeot used similar
pumps for their 1990's models from Power Packer. Replacements are not cheap., so I stripped and cleaned the motor and that fixed the problem.
A few observations:
- When looking for parts for the Ace I usually find they have been sourced from other vehicle manufactures or their suppliers. I.e Peugoet/Citroen, BMW, Porsche, Ford Europe and North America etc.
- Looking at similar cabriolet solutions on other vehicles I found that Audi, Alfa and Peugeot models from the 1990's
had the same open and closing sequences and used ECU and hydraulic pump components from "PowerPacker".
- I found that the same roof operation sequences are used for the Peugeot 306 cab, Audi 80 cab and Alfa Romeo 916 Spider, and that they are illustrated in videos
on Youtube, e.g. search for "Peugeot 306 cabriolet roof problems", see one example
https://www.youtube.com/watch?v=0shorR_3JAw- I searched for a more detailed description of the system used and I found a high level description of the Peugeot 306 with schematics from an
Australian site Peugeotlogic.com, look under the Workshop page, then Body Work. There you will find a guide provided by the Peugeot Cabriolet Owners Club.
I'm not suggesting you can transplant another roof onto your Ace, but this at least describes the roof operation principles in more detail than any
other information I have found sofar.

P.S. The Alfa hydraulic pump appears to have a 12 pipe manifold similar to the Ace.
