Blank plugs for the exhaust flaps?
 

I need to get a couple of blanking plugs for the connector which usually plugs into the actuator controlling the butterfly valve in the exhausts.
There are some available in the UK but seemingly for other models - are they a universal fit does anyone know?

Not an exact answer to your question, but this may help. The actuator used in the D4 A8 is also used in the following cars (over a period of different years), and has a 3-pin connector. I'm assuming these 'blanking' plugs have some sort of electronics in them so they don't throw an error code, so one specified for any of these models should in theory work. Have you tried asking the seller if they work for the A8, or if you could return them if they don't? If they do work, it also means the seller has more opportunities to sell them.
