If I remember correctly, someone also mentioned bad fuel as his cause for seal failure (which usually would be taken care of by a knock sensor and should not cause any parts to melt away).
Anyway, I guess one question would be if there was a single case of seal failure after they installed this ROM revision?

However, since most people have this ROM revision not installed, the probability of finding one with a seal failure would be very slim, even if there was still a chance of dealing with detonation after installing this ROM revision (since so far much less than 1% of all cars seem to be affected by this problem).
Btw, how would one get to this ROM revision anyway? Does one need to go to a dealer and specifically ask for it? Do they even know about this problem on a global level?
PS: Increasing power requires an increase of pressure in the combustion chamber and since p*V = n*R*T, going FI does at least increase the risk of detonation.
