Just posting the pictures I got from my mate on the french audi enthiusiast website.
This took plce in the office car park. Apparently fire started from the A3, burnt 6-7 other cars round it. Note the alloys melted!!!!! Battery exploded in A6 (note bonnet)
Was on an 03 plate. Scary. Hope mine never goes up in flames. Shouldn't do its 3 years newer!
