That's interesting....
Based on that answer, the RBF600 is fine. And their last response just means to change more frequently with a racing BF. If it was incompatible with Mg., it wouldn't matter how frequently you changed it.
This issue has obviously created a lot of confusion and know one seems to know for certain. The only way to find out the real facts would be to speak to a Motul chemist and varify that it is incompatible with Mg., as well as confirming with Audi that Mg. is in the brake system.

Well, it helps when you speak the language ;)
And your travels abroad sure come in handy, don't they? You can go straight to the source if needed... Next stop, MTM 
Still no reply from Benoit.

These are borate esters and very inert.
Actually, it was the addition of borate esters to the "normal" glycol ethers in DOT 3 fluids that allowed the higher boiling points of most DOT 4 and DOT 5.1 brake fluids.

Anyone want to buy three bottles of RBF 600? :-) j/k, I'll wait this one out.
In any case, it is indeed a pleasure to be part of a knowledgeable forum such as this to assist with questions like this.
Almost every week I learn something worthwhile from this forum. I just hope I can provide something in return now and then.

Not knowing what exactly's the borate ester in the fluid...
I won't say how reactive it is towards Mg compared to simple esters. Granted, it may be inert to heat, but towards reduction by Mg, need more info. Judging by what's classified as borate esters though, I think it would still have some reacitivity towards Mg.
